Filters

Filter objects intercept requests and responses during processing, and change them as follows:

Leave the request, response, and contexts unchanged. For example, the filter can simply can log the context as it passes through the filter.
In the request flow, change any aspect of the request (such as the URL, headers, or entity), or replace the request with a new Request object.
In the response flow, change any aspect of the response (such as the status, headers, or entity), or return a new Response instance

AllowOnlyFilter

Authorizes a request to continue processing if it satisfies at least one of the configured rules. Otherwise, passes the request to the FailureHandler or returns an HTTP 401 Unauthorized, with an empty response body.

This filter manages requests from the last request sender, otherwise called the request from the last hop, or the request from a direct client.

For debugging, configure the AllowOnlyFilter name, and add the following logger to logback.xml, replacing filter_name with the name:

org.forgerock.openig.filter.allow.AllowOnlyFilter.filter_name

For more information, see Managing logs.

When this property is configured, the destination path must match at least one path in the array.

Default: Any path is allowed.

"when": runtime expression<boolean>, optional

A flag to indicate that the request meets a condition. When true, the request is allowed.

The following condition is met when the first value of h1 is 1:

"when": "${request.headers['h1'][0] == '1'}"

Default: ${true}

"failureHandler": Handler reference, optional

Handler to treat the request if none of the declared rules are satisfied.

Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.

Default: HTTP 401 Unauthorized, with an empty response body.

Examples

In the following example, a request is authorized if the last request sender satisfies either of the following conditions:

Certificate subjectDN matches .*CN=test$ or CN=me, and the IP address is in the range 1.2.3.0/24.
IP address is 123.43.56.8.

"from": [
   {
     "certificate": {
          "subjectDNs": [".*CN=test$", "CN=me"]
     },
     "ip": {
       "list": ["1.2.3.0/24"]
     }
   },
   {
     "ip": {
       "list": ["123.43.56.8"]
     }
   },
]

In the following example, a request is authorized if the request destination satisfies all of the following conditions:

The host is myhost1.com or www.myhost1.com
The port is 80.
The method is POST or GET
The path matches /user/*.

"destination": [
  {
    "hosts": ["myhost1.com", "www.myhost1.com"],
    "ports": ["80"],
    "methods": ["POST", "GET"],
    "paths": ["/user/*"]
  }
]

The following example authorizes a request to continue processing if the requests meets the conditions set by either rule1 or rule2:

{
  "type": "AllowOnlyFilter",
  "config": {
    "rules": [
      {
        "name": "rule1",
        "from": [
          {
            "certificate": {
              "subjectDNs": [".*CN=test$", "CN=me"]
            },
            "ip": {
              "list": ["1.2.3.0/24"]
            }
          }
        ],
        "destination": [
          {
            "hosts": ["myhost1.com", "www.myhost1.com"],
            "ports": ["80"],
            "methods": ["POST", "GET"],
            "paths": ["/user/*"]
          }
        ],
        "when": "${request.headers['h1'][0] == '1'}"
      },
      {
        "name":"rule2",
        "when": "${request.headers['h1'][0] == '2'}"
      }
    ]
  }
}

AmSessionIdleTimeoutFilter

Forces the revocation of AM sessions that have been idle for a specified duration. The AmSessionIdleTimeoutFilter issues an authenticated and encrypted JWT to track activity on the AM session, and conveys it within a persistent cookie. The tracking token contains the following parts:

The time when the user was last active
A hash of the AM session cookie, to bind the tracking token to the AM session cookie
The idle timeout

Multiple filter instances can share the same tracking token, for example, in a clustered IG configuration, or when a federation of applications protected by authentication filters need to have a flexible idle timeout strategy.

AmSessionIdleTimeoutFilter requires the following configuration:

In AM, client-side sessions must be enabled for the realm in which the tracking token operates. See Configure client-side sessions in AM’s Sessions Guide.
In AM, client-side session denylisting must be enabled. See Configure client-side session denylisting in AM’s Sessions Guide.
The AmSessionIdleTimeoutFilter must be placed in a route before a filter that uses the AM session token, such as a SingleSignOnFilter or PolicyEnforcementFilter.
In production environments, and when multiple AmSessionIdleTimeoutFilters use the same tracking token, the encryption must not rely on the default configuration. It must be configured identically on each filter that uses the tracking token.

The following image shows the flow of information when an AmSessionIdleTimeoutFilter sits in front of a CrossDomainSingleSignOnFilter, to manage AM session timeout.

[1-5] When the AmSessionIdleTimeoutFilter receives an unauthenticated request, it passes the request along the chain, and the CrossDomainSingleSignOnFilter manages authentication.

[6-8] When the AmSessionIdleTimeoutFilter receives an authenticated request, it checks that the AM session token is valid, and then passes the request along the chain.

[9-10] If the AM session was valid, the AmSessionIdleTimeoutFilter issues a tracking token on the response flow, containing the following information:

Hash of the AM session token
Current timestamp
Idle timeout of the current filter

If the AM session was not valid, the AmSessionIdleTimeoutFilter does nothing on the response flow.

[11-12] The AmSessionIdleTimeoutFilter places the tracking token in persistent tracking cookie, and sends it with the response, to be used in the next request.

[13-15] When the same or another AmSessionIdleTimeoutFilter receives an authenticated request with a tracking token, it checks that the AM session token is valid, and checks that tracking token hash is bound to the AM session.

[16] Depending on the strategy set by idleTimeoutUpdate, the AmSessionIdleTimeoutFilter selects the value for idleTimeout from the tracking token (set by the AmSessionIdleTimeoutFilter in a previous request) or from its own value of idleTimeout (if this is a different instance of AmSessionIdleTimeoutFilter).

The AmSessionIdleTimeoutFilter checks for AM session timeout. If the last activity time plus the idle timeout is before the current time, the session has timed out. For example, a session with the following values has timed out:

last activity time: 15h30 today
idle timeout: 5 mins
current time: 15h40

[17-21] The AM session has timed out, so the AmSessionIdleTimeoutFilter does the following:

Forces AM to revoke the session.
Passes the request along the chain.
Expires the tracking cookie on the response flow, and sends it with the response.

[22-26] The session has not timed out, so the AmSessionIdleTimeoutFilter does the following:

Passes the request along the chain.
Updates the tracking token on the response flow, with the current timestamp and the value for idleTimeOut, using the same value for that was selected in step 16.
Places the tracking token in a persistent tracking cookie, and sends it with the response, to be used in the next request.

Usage

{
  "name": string,
   "type": "AmSessionIdleTimeoutFilter",
   "config": {
     "amService": AmService reference,
     "idleTimeout": configuration expression<duration>,
     "sessionToken": runtime expression<string>,
     "idleTimeoutUpdate": configuration expression<enumeration>,
     "secretsProvider": SecretsProvider reference,
     "encryptionSecretId": configuration expression<secret-id>,
     "encryptionMethod": configuration expression<string>,
     "cookie": object
   }
}

Properties

"amService": AmService reference, required

The AmService that refers to the AM instance that issue tracked session token.

"idleTimeout": configuration expression<duration>, required

The time a session can be inactive before it is considered as idle.

When an AmSessionIdleTimeoutFilter creates the tracking token, the token’s value for idleTimeout is set by this property. When a different AmSessionIdleTimeoutFilter accesses the same tracking token, depending on the strategy set by idleTimeoutUpdate, the token’s value for idleTimeout can be updated by the second AmSessionIdleTimeoutFilter.

"sessionToken": runtime expression<string>, optional

The location of the AM session token in the request. The following example accesses the first value of the request cookie iPlanetDirectoryPro:

"sessionToken": "${request.cookies['iPlanetDirectoryPro'][0].value}"

For information about the AM session cookie, refer to Find the name of your AM session cookie.

Default: ${request.cookies['<cookie name defined in the referenced AmService>'][0].value}

idleTimeoutUpdate: configuration expression<enumeration>, required

When multiple AmSessionIdleTimeoutFilters use the same tracking token, this property selects whether to use the idleTimeout from this filter or from the tracking token.

Use one of the following values:

NEVER: Use the idle timeout from the tracking token, and ignore the idle timeout from this filter.
ALWAYS: Use the idle timeout from this filter, and ignore the idle timeout from the tracking token.
INCREASE_ONLY: Compare the idle timeout from this filter and the tracking token, and use the longest value.
DECREASE_ONLY: Compare the idle timeout from this filter and the tracking token, and use the shortest value.

Default: ALWAYS

"secretsProvider": SecretsProvider reference, optional

The SecretsProvider to query for secrets to encrypt the tracking token.

"encryptionSecretId": configuration expression<secret-id>, optional

The secret ID of the encryption key used to encrypt the tracking cookie.

This secret ID must point to a CryptoKey.

In production environments, and when multiple AmSessionIdleTimeoutFilters use the same tracking cookie, the encryption must not rely on the default configuration. It must be configured identically on each filter that uses the cookie.

Authenticated encryption is achieved with a symmetric encryption key. Therefore, the secret must refer to a symmetric key.

For more information, refer to RFC 5116.

Default: When no secretsProvider is provides, IG generates a random symmetric key for authenticated encryption.

"encryptionMethod": configuration expression<string>, optional

The algorithm to use for authenticated encryption. For information about allowed encryption algorithms, refer to RFC 7518: "enc" (Encryption Algorithm) Header Parameter Values for JWE.

Default: A256GCM

"cookie": object, optional

Configuration of the activity tracking cookie.

{
  "name": configuration expression<string>,
  "domain": configuration expression<string>,
  "httpOnly": configuration expression<boolean>,
  "path": configuration expression<string>,
  "sameSite": configuration expression<enumeration>,
  "secure": configuration expression<boolean>
}

"name": configuration expression<string>, optional: The cookie name.

Default: x-ig-activity-tracker

"domain": configuration expression<string>, optional

Domain to which the cookie applies.

Default: The fully qualified hostname of the IG host.

"httpOnly": configuration expression<boolean>, optional

Flag to mitigate the risk of client-side scripts accessing protected cookies.

Default: true

"path": configuration expression<string>, optional

Path to apply to the cookie.

Default: /

"sameSite": configuration expression<enumeration>, optional

Options to manage the circumstances in which a cookie is sent to the server. Use one of the following values to reduce the risk of CSRF attacks:

STRICT: Send the cookie only if the request was initiated from the cookie domain. Not case-sensitive. Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
LAX: Send the cookie only with GET requests in a first-party context, where the URL in the address bar matches the cookie domain. Not case-sensitive. Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
NONE: Send the cookie whenever a request is made to the cookie domain. With this setting, consider setting secure to true to prevent browsers from rejecting the cookie. For more information, refer to SameSite cookies.

Default: Null

"secure": configuration expression<boolean>, optional

Flag to limit the scope of the cookie to secure channels.

Default: false

AssignmentFilter

Verifies that a specified condition is met. If the condition is met or if no condition is specified, the value is assigned to the target. Values can be assigned before the request is handled and after the response is handled.

Usage

{
  "name": string,
  "type": "AssignmentFilter",
  "config": {
    "onRequest": [
      {
        "condition": runtime expression<boolean>,
        "target": lvalue-expression,
        "value": runtime expression
      }, ...
    ],
    "onResponse": [
      {
        "condition": runtime expression<boolean>,
        "target": lvalue-expression,
        "value": runtime expression
      }, ...
    ]
  }
}

Properties

"onRequest": array of objects, optional: Defines a list of assignment bindings to evaluate before the request is handled.
"onResponse": array of objects, optional: Defines a list of assignment bindings to evaluate after the response is handled.
"condition": runtime expression<boolean>, optional: If the expression evaluates true, the value is assigned to the target.

Default: ${true}
"target": <lvalue-expression>, required: Expression that yields the target object whose value is to be set.
"value": runtime expression<object> , optional: The value to be set in the target. The value can be a string, information from the context, or even a whole map of information.

Examples

Add info to a session

The following example assigns a value to a session. Add the filter to a route to prevent IG from clearing up empty JWTSession cookies:

{
  "type": "AssignmentFilter",
  "config": {
    "onRequest": [{
      "target": "${session.authUsername}",
      "value": "I am root"
    }]
  }
}

Capture and store login credentials

The following example captures credentials and stores them in the IG session during a login request. Notice that the credentials are captured on the request but are not marked as valid until the response returns a positive 302. The credentials could then be used to log a user in to a different application:

{
  "name": "PortalLoginCaptureFilter",
  "type": "AssignmentFilter",
  "config": {
    "onRequest": [
      {
        "target": "${session.authUsername}",
        "value": "${request.queryParams['username'][0]}"
      },
      {
        "target": "${session.authPassword}",
        "value": "${request.queryParams['password'][0]}"
      },
      {
        "comment": "Authentication has not yet been confirmed.",
        "target": "${session.authConfirmed}",
        "value": "${false}"
      }
    ],
    "onResponse": [
      {
        "condition": "${response.status.code == 302}",
        "target": "${session.authConfirmed}",
        "value": "${true}"
      }
    ]
  }
}

AuthorizationCodeOAuth2ClientFilter

The AuthorizationCodeOAuth2ClientFilter uses OAuth 2.0 delegated authorization to authenticate end users. The filter can act as an OpenID Connect relying party or as an OAuth 2.0 client.

AuthorizationCodeOAuth2ClientFilter performs the following tasks:

Allows the user to select an authorization server from one or more static client registrations, or by discovery and dynamic registration.

In static client registration, authorization servers are provided by Issuer, and registrations are provided by ClientRegistration.
Redirects the user through the authentication and authorization steps of an OAuth 2.0 authorization code grant, which results in the authorization server returning an access token to the filter.
When an authorization grant succeeds, injects the access token data into a configurable target in the context so that subsequent filters and handlers can access the access token. Subsequent requests can use the access token without authenticating again.
When an authorization grant fails, invokes a failureHandler.

Service URIs

Service URIs are constructed from the clientEndpoint, as follows:

clientEndpoint/login/?discovery=user-input&goto=url: Discover and register dynamically with the end user’s OpenID Provider or with the client registration endpoint as described in RFC 7591, using the value of user-input.

After successful registration, redirect the end user to the provider for authentication and authorization consent. Then redirect the user agent back to the callback client endpoint, and then the goto URI.

The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.

To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
clientEndpoint/login?registration=clientId&issuer=issuerName&goto=url: Redirect the end user for authorization with the specified registration, defined by the ClientRegistration’s clientId and issuerName. For information, refer to ClientRegistration.

The provider corresponding to the registration then authenticates the end user and obtains authorization consent before redirecting the user agent back to the callback client endpoint.

If successful, the filter saves the authorization state in the session and redirects the user agent to the goto URL.

The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.

To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
clientEndpoint/logout?goto=url: Remove the authorization state for the end user, and redirect the request to the goto URL.

The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.

To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.

If no goto URL is specified in the request, use defaultLogoutGoto.
clientEndpoint/callback: Handle the callback from the OAuth 2.0 authorization server, that occurs as part of the authorization process.

If the callback is handled successfully, the filter saves the authorization state in the context at the specified target location and redirects to the URL provided to the login endpoint during login.
Other request URIs: Restore the authorization state in the specified target location, and call the next filter or handler in the chain.

Usage

{
  "name": string,
  "type": "AuthorizationCodeOAuth2ClientFilter",
  "config": {
    "clientEndpoint": runtime expression<uri string>,
    "failureHandler": Handler reference,
    "loginHandler": Handler reference,
    "registrations": [ ClientRegistration reference, ... ],
    "metadata": object,
    "cacheExpiration": configuration expression<duration>,
    "executor": ScheduledExecutorService reference,
    "target": lvalue-expression,

    "discoverySecretId": configuration expression<secret-id>,
    "tokenEndpointAuthMethod": configuration expression<enumeration>,
    "tokenEndpointAuthSigningAlg": configuration expression<string>,
    "oAuth2SessionKey": configuration expression<string>,
    "secretsProvider": SecretsProvider reference
  }
}

Properties

"clientEndpoint": runtime expression<url>, required

The URI to the client endpoint.

So that routes can accept redirects from the authorization server to the callback endpoint, the clientEndpoint must be the same as the route condition or a sub path of the route condition. For example:

The same as the route condition:

"condition": "${find(request.uri.path, '^/discovery')}"

"clientEndpoint": "/discovery"

As a sub path of the route condition:
```
"condition": "${find(request.uri.path, '^/home/id_token')}"
```
```
"clientEndpoint": "/home/id_token/sub-path"
```
Service URIs are constructed from the clientEndpoint. For example, when clientEndpoint is openid, the service URIs are /openid/login, /openid/logout, and /openid/callback. These endpoints are implicitly reserved, and attempts to access them directly can cause undefined errors.

The result of the expression must be a string that represents a valid URI, but is not a real java.net.URI object. For example, it would be incorrect to use ${request.uri}, which is not a String but a MutableUri.

See also Expressions.

"failureHandler": Handler reference, required

An inline handler configuration object, or the name of a handler object that is defined in the heap.

When the OAuth 2.0 Resource Server denies access to a resource, the failure handler can be invoked only if the error response contains a WWW-Authenticate header (meaning that there was a problem with the OAuth 2.0 exchange). All other responses are forwarded to the user agent without invoking the failure handler.

If the value of the WWW-Authenticate header is invalid_token, the AuthorizationCodeOAuth2ClientFilter tries to refresh the access token:

If the token is refreshed, the AuthorizationCodeOAuth2ClientFilter tries again to access the protected resource.
If the token is not refreshed, or if the second attempt to access the protected resource fails, the AuthorizationCodeOAuth2ClientFilter invokes the failure handler.

When the failure handler is invoked, the target in the context can be populated with information such as the exception, client registration, and error. The failure object in the target is a simple map, similar to the following example:
```
{
    "client_registration": "ClientRegistration name string",
    "error": {
        "realm": "optional string",
        "scope": [ "string (required by the client)", ... ],
        "error": "optional string",
        "error_description": "optional string",
        "error_uri": "optional string"
    },
    "access_token": "string",
    "id_token": "string",
    "token_type": "Bearer",
    "expires_in": "number",
    "scope": [ "optional scope string", ... ],
    "client_endpoint": "URL string",
    "exception": exception
}
```
In the failure object, the following fields are not always present. Their presence depends on when the failure occurs:
- "access_token"
- "id_token"
- "token_type"
- "expires_in"
- "scope"
- "client_endpoint"
  
  See also Handlers.

"loginHandler": Handler reference, required if there are zero or multiple client registrations, optional if there is one client registration

Use this Handler when the user must choose an authorization server. When registrations contains only one client registration, this Handler is optional but is displayed if specified.

Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.

See also Handlers.

"registrations": array of ClientRegistration references optional

List of client registrations that authenticate IG to the authorization server. The list must contain all client registrations that are to be used by the client filter.

The value represents a static client registration with an authorization server, as described in ClientRegistration.

"metadata": <object>, required for dynamic client registration and ignored otherwise

The values of the object are evaluated as configuration expression<strings>.

This object holds client metadata as described in OpenID Connect Dynamic Client Registration 1.0, and optionally a list of scopes. See that document for additional details and a full list of fields.

This object can also hold client metadata as described in RFC 7591, OAuth 2.0 Dynamic Client Registration Protocol. See that RFC for additional details.

The following partial list of metadata fields is not exhaustive, but includes metadata that is useful with AM as OpenID Provider:

"redirect_uris": array of configuration expression<url>, required

The array of redirection URIs to use when dynamically registering this client.

One of the registered values must match the clientEndpoint.

"client_name": configuration expression<string>, optional

Name of the client to present to the end user.

"scope": _configuration expression<string>, optional

Space-separated string of scopes to request of the OpenID Provider, for example:

"scope": "openid profile"

This property is available for dynamic client registration with AM, or with authorization servers that support RFC 7591, OAuth 2.0 Dynamic Client Registration Protocol

"cacheExpiration": configuration expression<duration>, optional

Duration for which to cache user-info resources.

IG lazily fetches user info from the OpenID provider. In other words, IG only fetches the information when a downstream Filter or Handler uses the user info. Caching allows IG to avoid repeated calls to OpenID providers when reusing the information over a short period.

Default: 10 minutes

Set this to disabled or zero to disable caching. When caching is disabled, user info is still lazily fetched.

"executor": ScheduledExecutorService reference, optional

A ScheduledExecutorService to schedule the execution of tasks, such as the eviction of entries in the OpenID Connect user information cache.

Default: ScheduledExecutorService

"target": lvalue-expression, optional

An expression that yields the target object. Downstream filters and handlers can use data in the target to enrich the existing request or create a new request.

When the target is openid, the following information can be provided in ${attributes.openid}:

access_token: Value of the OAuth 2.0 access token
scope: Scopes associated with the OAuth 2.0 access token
token_type: Authentication token type; for example, Bearer
expires_in: Number of milliseconds until the OAuth 2.0 access token expires
id_token: Value of the OpenID Connect token
id_token_claims: Claims used in the OpenID Connect token
client_endpoint: URL to the client endpoint
client_registration: Client ID of the OAuth 2.0 client that enables IG to communicate as an OAuth 2.0 client with an authorization server
user_info: Profile attributes of an authenticated user; for example, sub, name, family_name

Data is provided to the target as follows:

If the authorization process completes successfully, the AuthorizationCodeOAuth2ClientFilter injects the authorization state data into the target. In the following example, a downstream StaticRequestFilter retrieves the username and password from the target to log the user in to the sample application.
```
{
  "type": "StaticRequestFilter",
  "config": {
    "method": "POST",
    "uri": "http://app.example.com:8081/login",
    "form": {
      "username": [
        "${attributes.openid.user_info.sub}"
      ],
       "password": [
        "${attributes.openid.user_info.family_name}"
      ]
    }
  }
}
```
For information about setting up this example, refer to Authenticate Automatically to the Sample Application.
If the failure handler is invoked, the target can be populated with information such as the exception, client registration, and error, as described in "failureHandler" in this reference page.

Default: ${attributes.openid}

See also Expressions.

"defaultLoginGoto": runtime expression<url>,optional

After successful authentication and authorization, if the user accesses the clientEndpoint/login endpoint without providing a landing page URL in the goto parameter, the request is redirected to this URI.

The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.

To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.

The result of the expression must be a string that represents a valid URI, but is not a real java.net.URI object. For example, it would be incorrect to use ${request.uri}, which is not a String but a MutableUri.

Default: return an empty page.

"defaultLogoutGoto": runtime expression<url>,optional

If the user accesses the clientEndpoint/logout endpoint without providing a goto URL, the request is redirected to this URI.

The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.

To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.

Default: return an empty page.

"requireHttps": configuration expression<boolean>, optional: Whether to require that original target URI of the request (originalUri in UriRouterContext) uses the HTTPS scheme.

If the received request does not use HTTPS, it is rejected.

Default: true.

"requireLogin": configuration expression<boolean>, optional: Whether to require authentication for all incoming requests.

Default: true.

"issuerRepository": Issuer repository reference, optional: A repository of OAuth 2.0 issuers, built from discovered issuers and the IG configuration.

Provide the name of an IssuerRepository object defined in the heap.

Default: Look up an issuer repository named IssuerRepository in the heap. If none is explicitly defined, then a default one named IssuerRepository is created in the current route.

See also IssuerRepository.

"discoveryHandler": Handler reference, optional

Use this property for discovery and dynamic registration of OpenID Connect clients.

Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object. Usually set this to the name of a ClientHandler configured in the heap, or a chain that ends in a ClientHandler.

Default: The default ClientHandler.

CapturedUserPasswordFilter

Makes an AM password available to IG in the following steps:

Checks for the presence of the SessionInfoContext context, at ${contexts.amSession}.
- If the context is not present, or if sunIdentityUserPassword is null, the CapturedUserPasswordFilter collects session info and properties from AM.
- If the context is present and sunIdentityUserPassword is not null, the CapturedUserPasswordFilter uses that value for the password.
The CapturedUserPasswordFilter decrypts the password and stores it in the CapturedUserPasswordContext, at ${contexts.capturedPassword}.

Usage

CertificateThumbprintFilter

Extracts a Java certificate from a trusted header or from a TLS connection, computes the SHA-256 thumbprint of that certificate, and makes the thumbprint available for the ConfirmationKeyVerifierAccessTokenResolver. Use this filter to enable verification of certificate-bound access tokens.

CertificateThumbprintFilter computes and makes available the SHA-256 thumbprint of a client certificate as follows:

Evaluates a runtime expression and yields a java.security.cert.Certificate
Hashes the certificate using SHA-256
Base64url-encodes the result
Stores the result in the contexts chain

The runtime expression can access or build a client certificate from any information present at runtime, such as a PEM in a header, or a pre-built certificate.

Use CertificateThumbprintFilter with ConfirmationKeyVerifierAccessTokenResolver when the IG instance is behind the TLS termination point, for example, when IG is running behind a load balancer or other ingress point.

Usage

{
  "name": string,
  "type": "CertificateThumbprintFilter",
  "config": {
    "certificate": runtime expression<certificate>,
    "failureHandler": Handler reference,
  }
}

Properties

"certificate": runtime expression<certificate>, required

An EL expression which, when evaluated, yields an instance of a java.security.cert.Certificate.

Use the following Functions in the expression to define hash, decoding, and certificate format:

digestSha256, to calculate the SHA-256 hash of the certificate.
decodeBase64url, to decode an incoming base64url-encoded string.
pemCertificate, to convert a PEM representation string into a certificate.

See Examples.

"failureHandler": Handler reference, optional: Handler to treat the request on failure.

Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.

Default: HTTP 403 Forbidden, the request stops being executed.

Examples

The following example use the certificate associated with the incoming HTTP connection:

{
  "name": "CertificateThumbprintFilter-1",
  "type": "CertificateThumbprintFilter",
  "config": {
    "certificate": "${contexts.client.certificates[0]}"
  }
}

The following example is adapted for a deployment with NGINX as the TLS termination, where NGINX fronts IG. NGINX provides the client certificate associated with its own incoming connection in the x-ssl-client-cert header. The certificate is encoded as PEM, and then url-encoded:

{
  "name": "CertificateThumbprintFilter-2",
  "type": "CertificateThumbprintFilter",
  "config": {
    "certificate": "${pemCertificate(urlDecode(request.headers['x-ssl-client-cert'][0]))}"
  }
}

CircuitBreakerFilter

Monitors failures. When the number of failures reaches a configured failure threshold, the circuit breaker trips, and the circuit is considered open. Calls to downstream filters are stopped, and a runtime exception is returned.

After a configured delay, the circuit breaker is reset, and is the circuit considered closed. Calls to downstream filters are restored.

Usage

{
  "name": string,
  "type": "CircuitBreakerFilter",
  "config": {
    "maxFailures":  configuration expression<integer>,
    "openDuration": configuration expression<duration>,
    "openHandler": Handler reference,
    "slidingCounter": object,
    "executor":  ScheduledExecutorService reference
  }
}

Properties

"maxFailures": configuration expression<number>, required

The maximum number of failed requests allowed in the window given by size, before the circuit breaker trips. The value must be greater than zero.

"openDuration": configuration expression<duration>, required

The duration for which the circuit stays open after the circuit breaker trips. The executor schedules the circuit to be closed after this duration.

"openHandler": Handler reference, optional

The Handler to call when the circuit is open.

Default: A handler that throws a RuntimeException with a "circuit-breaker open" message.

"slidingCounter": object, optional

A sliding window error counter. The circuit breaker trips when the number of failed requests in the number of requests given by size reaches maxFailures.

The following image illustrates how the sliding window counts failed requests:

{
  "slidingCounter":  {
    "size": configuration expression<number>
  }
}

"size": configuration expression<number>, required: The size of the sliding window in which to count errors.

The value of size must be greater than zero, and greater than the value of maxFailures, otherwise an exception is thrown.

"executor": ScheduledExecutorService reference, optional

A ScheduledExecutorService to schedule closure of the circuit after the duration given by openDuration.

Default: The default ScheduledExecutorService in the heap

Example

In the following example, the circuit breaker opens after 11 failures in the previous 100 requests, throwing a runtime exception with a "circuit-breaker open" message. The default ScheduledExecutorService in the heap closes the circuit-breaker after 10 seconds.

{
  "type": "CircuitBreakerFilter",
  "config": {
    "maxFailures": 10,
    "openDuration": "10 seconds",
    "openHandler": {
      "type": "StaticResponseHandler",
      "config": {
        "status": 500,
        "headers": {
          "Content-Type": [ "text/plain" ]
        },
        "entity": "Too many failures; circuit opened to protect downstream services."
      }
    },
    "slidingCounter": {
      "size": 100
    }
  }
}

ClientCredentialsOAuth2ClientFilter

Authenticates OAuth 2.0 clients by using the client’s OAuth 2.0 credentials to obtain an access token from an authorization server, and injecting the access token into the inbound request as a Bearer Authorization header. The access token is valid for the configured scopes.

The ClientCredentialsOAuth2ClientFilter obtains the client’s access token by using the client_credentials grant type. Client authentication is provided by the endpointHandler property, which uses a client authentication filter, such as ClientSecretBasicAuthenticationFilter. The filter refreshes the access token as required.

Use the ClientCredentialsOAuth2ClientFilter in a service-to-service context, where services need to access resources protected by OAuth 2.0.

Usage

{
  "name": string,
  "type": "ClientCredentialsOAuth2ClientFilter",
  "config": {
    "secretsProvider": SecretsProvider reference,
    "tokenEndpoint": configuration expression<url>,
    "scopes": [ configuration expression<string>, ... ],
    "endpointHandler": Handler reference,
    "clientId": configuration expression<sting>, //deprecated
    "clientSecretId": configuration expression<secret-id>, //deprecated
    "handler": Handler reference //deprecated
  }
}

Properties

"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.

"tokenEndpoint": configuration expression<url>, required

The URL to the authorization server’s OAuth 2.0 token endpoint.

"scopes": array of configuration expression<strings>, optional

Array of scope strings to request from the authorization server.

Default: Empty, request no scopes.

"endpointHandler": Handler reference, optional

The Handler to exchange tokens on the authorization endpoint.

Configure this property as a Chain, using one of the following client authentication filters:

ClientSecretBasicAuthenticationFilter
ClientSecretPostAuthenticationFilter
PrivateKeyJwtClientAuthenticationFilter

{
  "name": "myHandler",
  "type": "Chain",
  "config": {
    "handler": "ForgeRockClientHandler",
    "filters": [
      {
        "type": "ClientSecretBasicAuthenticationFilter",
        "config": {
          "clientId": "myConfidentialClient",
          "clientSecretId": "my.client.secret.id",
          "secretsProvider" : "mySystemAndEnvSecretStore",
        }
      }
    ]
  }
}

Default: ForgeRockClientHandler

"clientId": configuration expression<string>, required

This property is deprecated. Use endpointHandler instead. For more information, refer to the Deprecated section of the Release Notes.

The ID of the OAuth 2.0 client registered with the authorization server.

If you use the deprecated properties, provide clientId, clientSecretId to obtain the client secret, which authenticates using the client_secret_basic method.

"clientSecretId": configuration expression<secret-id>, required

This property is deprecated. Use endpointHandler instead. For more information, refer to the Deprecated section of the Release Notes.

The ID to use when querying the secretsProvider for the client secret.

This secret ID must point to a GenericSecret.

"handler": Handler reference or inline Handler declaration, optional

This property is deprecated. Use endpointHandler instead. For more information, refer to the Deprecated section of the Release Notes.

OAuth2ResourceServerFilter

The OAuth 2.0 Authorization Framework

The OAuth 2.0 Authorization Framework: Bearer Token Usage

ClientSecretBasicAuthenticationFilter

Supports client authentication with the method client_secret_basic. Clients that have received a client_secret value from the authorization server authenticate through the HTTP basic access authentication scheme, as in the following example:

POST /oauth2/token HTTP/1.1
Host: as.example.com
Authorization: Basic ....
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&
code=...

Use this filter with an endpoint Handler that requires client_secret_basic authentication. For example, endpointHandler in the OAuth2TokenExchangeFilter or ClientCredentialsOAuth2ClientFilter.

Usage

{
  "name": string,
  "type": "ClientSecretBasicAuthenticationFilter",
  "config": {
    "clientId": configuration expression<string>,
    "clientSecretId": configuration expression<secret-id>,
    "secretsProvider": SecretsProvider reference
  }
}

Configuration

"clientId": configuration expression<string>, required: The OAuth 2.0 client ID to use for authentication.
"clientSecretId": configuration expression<secret-id>, required: The OAuth 2.0 client secret to use for authentication.

This secret ID must point to a GenericSecret.
"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.

Example

{
  "name": "ExchangeHandler",
  "type": "Chain",
  "config": {
    "handler": "ForgeRockClientHandler",
    "filters": [
      {
        "type": "ClientSecretBasicAuthenticationFilter",
        "config": {
          "clientId": "serviceConfidentialClient",
          "clientSecretId": "client.secret.id",
          "secretsProvider" : "SystemAndEnvSecretStore-1"
        }
      }
    ]
  }
}

ClientSecretPostAuthenticationFilter

Supports client authentication with the method client_secret_post. Clients that have received a client_secret value from the authorization server authenticate by including the client credentials in the request body, as in the following example:

POST /oauth2/token HTTP/1.1
Host: as.example.com
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&;
client_id=...&
client_secret=...&
code=...

Use this filter with an endpoint Handler that requires client_secret_post authentication. For example, endpointHandler in the OAuth2TokenExchangeFilter or ClientCredentialsOAuth2ClientFilter.

Usage

{
  "name": string,
  "type": "ClientSecretPostAuthenticationFilter",
  "config": {
    "clientId": configuration expression<string>,
    "clientSecretId": configuration expression<secret-id>,
    "secretsProvider": SecretsProvider reference
  }
}

Configuration

"clientId": configuration expression<string>, required: The OAuth 2.0 client ID to use for authentication.
"clientSecretId": configuration expression<secret-id>, required: The OAuth 2.0 client secret to use for authentication.

This secret ID must point to a GenericSecret.
"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.

ConditionalFilter

Verifies that a specified condition is met. If the condition is met, the request is dispatched to a delegate Filter. Otherwise, the delegate Filter is skipped.

Use ConditionalFilter to easily use or skip a Filter depending on whether a condition is met. To easily use or skip a set of Filters, use a ChainOfFilters as the delegate Filter and define a set of Filters. For information, refer to ChainOfFilters.

Usage

{
    "name": string,
    "type": "ConditionalFilter",
    "config": {
        "condition": runtime expression<boolean>,
        "delegate": Filter reference
   }
}

Properties

"condition": runtime expression<boolean>, required: If the expression evaluates to true, the request is dispatched to the delegate Filter. Otherwise the delegate Filter is skipped.
"delegate": Filter reference, required: Filter to treat the request when the condition expression evaluates as true.

See also Filters.

Example

The following example tests whether a request finishes with .js or .jpg:

{
  "type": "Chain",
  "config": {
    "filters": [{
      "type": "ConditionalFilter",
      "config": {
        "condition": "${not (find(request.uri.path, '.js$') or find(request.uri.path, '.jpg$'))}",
        "delegate": "mySingleSignOnFilter"
      }
    }],
    "handler": "ReverseProxyHandler"
  }
}

If the request is to access a .js file or .jpg file, it skips the delegate SingleSignOnFilter filter declared in the heap, and passes straight to the ReverseProxyHandler.

If the request is to access another type of resource, it must pass through the delegate SingleSignOnFilter for authentication with AM before it can pass to the ReverseProxyHandler.

More information

org.forgerock.openig.filter.ConditionalFilter

ConditionEnforcementFilter

Verifies that a specified condition is met. If the condition is met, the request continues to be executed. Otherwise, the request is referred to a failure handler, or IG returns 403 Forbidden and the request is stopped.

Usage

{
    "name": string,
    "type": "ConditionEnforcementFilter",
    "config": {
        "condition": runtime expression<boolean>,
        "failureHandler": Handler reference
    }
}

Properties

"condition": runtime expression<boolean>, required: If the expression evaluates to true, the request continues to be executed.
"failureHandler": Handler reference, optional: Handler to treat the request if the condition expression evaluates as false.

Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.

Default: HTTP 403 Forbidden, the request stops being executed.

Example

The following example tests whether a request contains a session username. If it does, the request continues to be executed. Otherwise, the request is dispatched to the ConditionFailedHandler failure handler.

{
    "name": "UsernameEnforcementFilter",
    "type": "ConditionEnforcementFilter",
    "config": {
        "condition": "${not empty (session.username)}",
        "failureHandler": "ConditionFailedHandler"
    }
}

More information

org.forgerock.openig.filter.ConditionEnforcementFilter

ChainOfFilters

Dispatches a request to an ordered list of filters. Use this filter to assemble a list of filters into a single filter that you can then use in different places in the configuration.

A ChainOfFilters can be placed in a configuration anywhere that a filter can be placed.

Unlike Chain, ChainOfFilters does not finish by dispatching the request to a handler. For more information, see Chain.

Usage

{
    "name": string,
    "type": "ChainOfFilters",
    "config": {
        "filters": [ Filter reference, ... ]
    }
}

Properties

"filters": array of Filter references, required: An array of names of filter objects defined in the heap, and inline filter configuration objects.

The chain dispatches the request to these filters in the order they appear in the array.

See also Filters.

Example

{
    "name": "MyChainOfFilters",
    "type": "ChainOfFilters",
    "config": {
        "filters": [ "Filter1", "Filter2" ]
   }
}

         "relayed": [ configuration expression<string>, ... ],
         "defaultAction": configuration expression<enumeration>
     }
}

Properties

"managed": array of configuration expression<strings>, optional

A list of the names of cookies to be managed.

IG stores cookies from the protected application in the session and manages them as follows:

Requests with a Cookie header: IG removes managed cookies so that protected applications cannot see them.
Responses with a Set-Cookie header: IG removes managed cookies and keeps a copy of them. IG then adds the managed cookies in a Cookie header to future requests that traverse the CookieFilter.

"suppressed": array of configuration expression<strings>, optional

A list of the names of cookies to be suppressed.

IG removes cookies from the request and response. Use this option to hide domain cookies, such as the AM session cookie, that are used by IG but are not usually used by protected applications.

"relayed": array of configuration expression<strings>, optional

A list of the names of cookies to be relayed.

IG transmits cookies freely from the user agent to the remote server, and vice versa.

"defaultAction": configuration expression<enumeration>, optional

Action to perform for cookies that do not appear in one of the above lists. Set to MANAGE, SUPPRESS, or RELAY.

If a cookie appears in more than one of the above lists, it is treated in the following order of precedence: managed, suppressed, relayed. For example, if a cookie is in both the managed and relayed lists, the cookie is managed.

Default: "MANAGE".

CorsFilter

Configures policies for cross-origin resource sharing (CORS), to allow cross-domain requests from user agents.

Usage

{
   "name": string,
   "type": "CorsFilter",
   "config": {
     "policies": [ object, ... ],
     "failureHandler": Handler reference
   }
}

Properties

"policies": array of objects, required

One or more policies to apply to the request. A policy is selected when the origin of the request matches the accepted origins of the policy.

When multiple policies are declared, they are tried in the order that they are declared, and the first matching policy is selected.

{
  "acceptedOrigins": [ configuration expression<url>, ... ] or "*",
  "acceptedMethods": [ configuration expression<string>, ... ] or "*",
  "acceptedHeaders": [ configuration expression<string>, ... ] or "*",
  "exposedHeaders": [ configuration expression<string>, ... ],
  "maxAge": configuration expression<duration>,
  "allowCredentials": configuration expression<boolean>,
  "origins": [ configuration expression<url>, ... ] or "*" //deprecated
}

"acceptedOrigins": array of configuration expression<urls> or "*", required

A comma-separated list of origins, to match the origin of the CORS request. Alternatively, use * to allow requests from any URL.

If the request origin is not in the list of accepted origins, the failure handler is invoked or an HTTP 403 Forbidden is returned, and the request stops being executed.

Origins are URLs with a scheme, hostname, and optionally a port number, for example, http://www.example.com. If a port number is not defined, origins with no port number or with the default port number (80 for HTTP, 443 for HTTPS) are accepted.

Examples:

{
  "acceptedOrigins": [
    "http://www.example.com",
    "https://example.org:8433"
  ]
}

{
  "acceptedOrigins": "*"
}

"acceptedMethods": array of configuration expression<strings> or "*", optional

A comma-separated list of case-sensitive HTTP method names that are allowed when making CORS requests. Alternatively, use * to allow requests with any method.

In preflight requests, browsers use the Access-Control-Request-Method header to let the server know which HTTP method might be used in the actual request.

If all requested methods are allowed, the requested methods are returned in the preflight response, in the Access-Control-Allow-Methods header.
If any requested method is not allowed, the Access-Control-Allow-Methods header is omitted. The failure handler is not invoked, but the user agent interprets the preflight response as a CORS failure.

Examples:

{
  "acceptedMethods": [
    "GET",
    "POST",
    "PUT",
    "MyCustomMethod"
  ]
}

{
  "acceptedMethods": "*"
}

Default: All methods are rejected.

"acceptedHeaders": array of configuration expression<strings> or "*", optional

A comma-separated list of case-insensitive request header names that are allowed when making CORS requests. Alternatively, use * to allow requests with any header.

In preflight requests, browsers use the Access-Control-Request-Headers header to let the server know which HTTP headers might be used in the actual request.

If all requested headers are allowed, the requested headers are returned in the preflight response, in the Access-Control-Allow-Headers header.
If any requested header is not allowed, the Access-Control-Allow-Headers header is omitted. The failure handler is not invoked, but the user agent interprets the preflight response as a CORS failure.

Examples:

{
  "acceptedHeaders": [
    "iPlanetDirectoryPro",
    "X-OpenAM-Username",
    "X-OpenAM-Password",
    "Accept-API-Version",
    "Content-Type",
    "If-Match",
    "If-None-Match"
  ]
}

{
  "acceptedHeaders": "*"
}

Default: All requested headers are rejected.

"exposedHeaders": list of configuration expression<string>, optional

A comma-separated list of case-insensitive response header names that are returned in the Access-Control-Expose-Headers header.

Only headers in this list, safe headers, and the following simple response headers are exposed to frontend JavaScript code:

Cache-Control
Content-Language
Expires
Last-Modified
Pragma
Content-Type

Example:

{
  "exposedHeaders": [
    "Access-Control-Allow-Origin",
    "Access-Control-Allow-Credentials",
    "Set-Cookie"
  ]
}

Default: No headers are exposed.

"maxAge": configuration expression<duration>, optional

The maximum duration for which a browser is allowed to cache a preflight response. The value is included in the Access-Control-Max-Age header of preflight responses.

When this maxAge is greater than the browser’s maximum internal value, the browser value takes precedence.

Default: 5 seconds

"allowCredentials": configuration expression<boolean>, optional

A flag to allow requests that use credentials, such as cookies, authorization headers, or TLS client certificates.

Set to true to set the Access-Control-Allow-Credentials header to true, and allow browsers to expose the response to frontend JavaScript code.

Default: False

"origins": list of configuration expression<url> or "*", required

This property is deprecated; use acceptedOrigins instead. For more information, refer to the Deprecated section of the Release Notes.

A comma-separated list of origins, to match the origin of the CORS request. Alternatively, use * to allow requests from any URL.

"failureHandler": Handler reference, optional

Handler invoked during the preflight request, when the request origin does not match any of the acceptedOrigins defined in policies.

The failure handler is not invoked when requested headers or requested methods are not allowed.

Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.

Default: HTTP 403 Forbidden, the request stops being executed.

CrossDomainSingleSignOnFilter

When IG and AM are running in the same domain, the SingleSignOnFilter can be used for SSO. When IG and AM are running in different domains, AM cookies are not visible to IG because of the same-origin policy. The CrossDomainSingleSignOnFilter provides a mechanism to push tokens issued by AM to IG running in a different domain.

When this filter processes a request, it injects the CDSSO token, the session user ID, and the full claims set into the CdSsoContext. Should an error occur during authentication, the error details are captured in a CdSsoFailureContext.

For an example of how to configure CDSSO in AM and IG, and information about the flow of data between AM, IG, and a protected application, refer to Authenticate with CDSSO.

WebSocket notifications for sessions

When WebSocket notifications are set up for sessions, IG receives a notification from AM when a user logs out of AM, or when the AM session is modified, closed, or times out. IG then evicts entries that are related to the event from the sessionCache.

For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.

Usage

{
  "name": string,
  "type": "CrossDomainSingleSignOnFilter",
  "config": {
    "amService": AmService reference,
    "redirectEndpoint": configuration expression<url>,
    "authenticationService": configuration expression<string>,
    "authCookie": object,
    "defaultLogoutLandingPage": configuration expression<url>,
    "logoutExpression": runtime expression<boolean>,
    "failureHandler": Handler reference,
    "verificationSecretId": configuration expression<secret-id>,
    "secretsProvider": SecretsProvider reference
  }
}

Properties

"amService": AmService reference, required

The AmService heap object to use. See AmService.

"redirectEndpoint": configuration expression<url>, required

The URI to which AM redirects the browser with the authentication token or an authentication error. The filter checks that the authentication was initiated by IG.

Configure this URI to be the same as that in AM.

To make sure the redirect is routed back to the CrossDomainSingleSignOnFilter, include the endpoint in the route condition in one of the following ways:

As a sub-path of the condition path.

For example, use the following route condition with the following endpoint:
```
"condition": "${find(request.uri.path, '^/home/cdsso')}"
```
```
"redirectEndpoint": "/home/cdsso/callback"
```
To match the route condition.

For example, use the following route condition with the following endpoint:
```
"condition": "${find(request.uri.path, '^/home/cdsso')}"
```
```
"redirectEndpoint": "/home/cdsso"
```
With this route condition, all POST requests on the condition path are treated as AM CDSSO callbacks. Any POST requests that aren’t the result of an AM CDSSO callback will fail.
As a specific path that is not related to the condition path.

To make sure the redirect is routed back to this filter, include the redirectEndpoint as a path in the filter condition.

For example, use the following route condition with the following endpoint:
```
"condition": "${find(request.uri.path, '^/home/cdsso/redirect') || find(request.uri.path, '^/ig/cdssoRedirectUri')}"
```
```
"redirectEndpoint": "/ig/cdssoRedirectUri"
```

"authenticationService": configuration expression<string>,optional

The name of an AM authentication tree or authentication chain to use for authentication.

Use only authentication trees with ForgeRock Identity Cloud. Authentication modules and chains are not supported.

Default: AM’s default authentication tree.

For more information about authentication trees and chains, refer to Authentication nodes and trees and Authentication modules and chains in AM’s Authentication and SSO guide.

"authCookie": object, optional

The configuration of the cookie used to store the authentication.

{
  "name": configuration expression<string>,
  "domain": configuration expression<string>,
  "httpOnly": configuration expression<boolean>,
  "path": configuration expression<string>,
  "sameSite": configuration expression<enumeration>,
  "secure": configuration expression<boolean>
}

"name": configuration expression<string>, optional

Name of the cookie containing the authentication token from AM.

For security, change the default name of cookies.

Default: ig-token-cookie

"domain": configuration expression<string>, optional

Domain to which the cookie applies.

Set a domain only if the user agent is able to re-emit cookies on that domain on its next hop. For example, to re-emit a cookie on the domain example.com, the user agent must be able to access that domain on its next hop.

Default: The fully qualified hostname of the user agent’s next hop.

"httpOnly": configuration expression<boolean>, optional

Flag to mitigate the risk of client-side scripts accessing protected cookies.

Default: true

"path": configuration expression<string>, optional

Path protected by this authentication.

Set a path only if the user agent is able to re-emit cookies on the path. For example, to re-emit a cookie on the path /home/cdsso, the user agent must be able to access that path on its next hop.

Default: The path of the request that got the Set-Cookie in its response.

"sameSite": configuration expression<enumeration>, optional

Options to manage the circumstances in which a cookie is sent to the server. Use one of the following values to reduce the risk of CSRF attacks:

STRICT: Send the cookie only if the request was initiated from the cookie domain. Not case-sensitive.

Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
LAX: Send the cookie only with GET requests in a first-party context, where the URL in the address bar matches the cookie domain. Not case-sensitive.

Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
NONE: Send the cookie whenever a request is made to the cookie domain. Not case-sensitive.

With this setting, consider setting secure to true to prevent browsers from rejecting the cookie. For more information, refer to SameSite cookies.

Default: LAX

For CDSSO, set "sameSite":"none" and "secure":"true". For security reasons, many browsers require the connection used by the browser to be secure (HTTPS) for "sameSite":"none". Therefore, if the connection used by the browser is not secure (HTTP), the browser might not supply cookies with "sameSite":"none". For more information, refer to Authenticate with CDSSO.

"secure": configuration expression<boolean>, optional: Flag to limit the scope of the cookie to secure channels.

Set this flag only if the user agent is able to re-emit cookies over HTTPS on its next hop. For example, to re-emit a cookie with the secure flag, the user agent must be connected to its next hop by HTTPS.

Default: false

"defaultLogoutLandingPage": configuration expression<url>, optional: The URL to which a request is redirected if logoutExpression is evaluated as true.

If this property is not an absolute URL, the request is redirected to the IG domain name.

This parameter is effective only when logoutExpression is specified.

Default: None, processing continues.

"logoutExpression": runtime expression<boolean>, optional

A flag to indicate that a logout condition is met. The condition is based on the request:

true: The AM session token for the end user is revoked. If a defaultLogoutLandingPage is specified, the request is redirected to that page.
false: The request continues to be processed.

The following example expressions can be used to trigger revocation of the end user token:
The request URI contains /logout:
```
${find(request.uri, '/logout')}
```
The request path starts with /logout:
```
${find(request.uri.path, '^/logout')}
```
The request query includes the logOff=true query parameter:
```
${find(request.uri.query, 'logOff=true')}
```

Default: ${false}

"failureHandler": Handler reference, optional

Handler to treat the request if an error occurs during authentication.

If an error occurs during authentication, a CdSsoFailureContext is populated with details of the error and any associated Throwable. This is available to the failure handler so that it can respond appropriately.

Be aware that the failure handler does not itself play a role in user authentication. It is only invoked if there is a problem that prevents user authentication from taking place.

A number of circumstances may cause the failure handler to be invoked, including:

The redirect endpoint is invalid.
The redirect endpoint is invoked without a valid CDSSO token.
The redirect endpoint is invoked inappropriately.
An error was reported by AM during authentication.

If no failure handler is configured, the default failure handler is used.

See also Handlers.

Default: HTTP 200 OK. The response entity contains details of the error.

"verificationSecretId": configuration expression<secret-id>, required to verify the signature of signed tokens: The secret ID for the secret to verify the signature of signed tokens.

This secret ID must point to a CryptoKey.

If configured, the token must be signed. If not configured, IG does not verify the signature.

For information about how signatures are validated, refer to Validating the signature of signed tokens. For information about how each type of secret store resolves named secrets, refer to Secrets.
"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.

Example

In the following example from Authentication, IG uses authentication from AM on a different domain to process a request:

{
  "name": "cdsso",
  "baseURI": "http://app.example.com:8081",
  "condition": "${find(request.uri.path, '^/home/cdsso')}",

CsrfFilter

Prevent Cross Site Request Forgery (CSRF) attacks when using cookie-based authentication, as follows:

When a session is created or updated for a client, generate a CSRF token as a hash of the session cookie.
Send the token in a response header to the client, and require the client to provide that header in subsequent requests.
In subsequent requests, compare the provided token to the generated token.
If the token is not provided or can’t be validated, reject the request and return a valid CSRF token transparently in the response header.

Rogue websites that attempt CSRF attacks operate in a different website domain to the targeted website. Because of same-origin policy, rogue websites can’t access a response from the targeted website, and cannot, therefore, access the CSRF token.

Usage

{
  "name": string,
  "type": "CsrfFilter",
  "config": {
    "cookieName": configuration expression<string>,
    "headerName": configuration expression<string>,
    "excludeSafeMethods": configuration expression<boolean>,
    "failureHandler": Handler reference
  }
}

Properties

"cookieName": configuration expression<string>, required

The name of the HTTP session cookie used to store the session ID. For example, use the following cookie names for the following processes:

SSO with the SingleSignOnFilter: Use the name of the AM HTTP session cookie, (default, iPlanetDirectoryPro). For information about the AM session cookie, see Find the name of your AM session cookie.
CDSSO with the CrossDomainSingleSignOnFilter: Use the name configured in authCookie.name.
OpenID Connect with the AuthorizationCodeOAuth2ClientFilter: Use the name of the IG HTTP session cookie (default, IG_SESSIONID). For information about the IG session cookie, see admin.json.
SAML: Use the name of the IG HTTP session cookie (default, IG_SESSIONID). For information about the IG session cookie, see admin.json.

"headerName": configuration expression<string>, optional

The name of the header that carries the CSRF token. The same header is used to create and verify the token.

Default: X-CSRF-Token

"excludeSafeMethods": configuration expression<boolean>, optional

Whether to exclude GET, HEAD, and OPTION methods from CSRF testing. In most cases, these methods are assumed as safe from CSRF.

Default: true

"failureHandler": Handler reference, optional

Handler to treat the request if the CSRF the token is not provided or can’t be validated. Provide an inline handler declaration, or the name of a handler object defined in the heap.

Although IG returns the CSRF token transparently in the response header, this handler cannot access the CSRF token.

Default: Handler that generates HTTP 403 Forbidden.

Example

For an example of how to harden protection against CSRF attacks, see CSRF protection.

{
  "name": "CsrfFilter-1",
  "type": "CsrfFilter",
  "config": {
    "cookieName": "openig-jwt-session",

DataPreservationFilter

The DataPreservationFilter triggers POST data preservation when an unauthenticated client posts HTML form data to a protected resource.

When an authentication redirect is triggered, the filter stores the data in the HTTP session, and redirects the client for authentication. After authentication, the filter generates an empty self-submitting form POST to emulate the original POST. It then replays the stored data into the request before passing it along the chain.

The data can be any POST content, such as HTML form data or a file upload.

For more information, refer to POST data preservation.

Usage

{
  "type": "DataPreservationFilter",
  "config": {
    "noJavaScriptMessage": configuration expression<string>,
    "maxContentLength": configuration expression<positive integer>
  }
}

Properties

"noJavaScriptMessage": configuration expression<string>, optional: JavaScript is used to replay the preserved data from the original POST that triggered the login redirect. This property configures a message to display if the user-agent does not support JavaScript.

Default: Javascript is disabled in your browser, click on this button to replay the preserved original request
"maxContentLength": configuration expression<positive integer>, optional: The maximum number of bytes of POST data the filter can preserve. The size is taken from the Content-Length header.

Default: 4096

Example

For an example of use, refer to POST data preservation.

EncryptedPrivateKeyJwtClientAuthenticationFilter

Supports client authentication with the private_key_jwt client-assertion, using a signed and encrypted JWT.

Clients send a signed and encrypted JWT to the authorization server. IG builds, signs and encrypts the JWT, and prepares the request as in the following example:

POST /token HTTP/1.1
Host: as.example.com
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&
code=...&
client_id=<clientregistration_id>&
client_assertion_type=urn%3Aietf%3Aparams%3Aoauth%3Aclient-assertion-type%3Ajwt-bearer&
client_assertion=PHNhbWxwOl ... ZT

Use this filter with an endpoint Handler that requires authentication with the private_key_jwt client-assertion, using an encrypted JWT. For example, the endpointHandler handler in the OAuth2TokenExchangeFilter.

EntityExtractFilter

Extracts regular expression patterns from a message entity, and stores their values in a target object. Use this object in password replay, to find a login path or extract a nonce.

If the message type is REQUEST, the pattern is extracted before the request is handled. If the message type is RESPONSE, the pattern is extracted out of the response body.

Each pattern can have an associated template, which is applied to its match result.

For information, see Patterns.

Usage

{
    "name": string,
    "type": "EntityExtractFilter",
    "config": {
        "messageType": configuration expression<enumeration>,
        "charset": configuration expression<string>,
        "target": lvalue-expression,
        "bindings": [
            {
                "key": configuration expression<string>,
                "pattern": pattern,
                "template": pattern
            }, ...
        ]
    }
}

Properties

"messageType": configuration expression<enumeration>, required: The message type to extract patterns from.

Must be REQUEST or RESPONSE.
"charset": configuration expression<string>, optional: Overrides the character set encoding specified in message.

Default: The message encoding is used.
"target": <lvalue-expression>, required: Expression that yields the target object that contains the extraction results.

The bindings determine what type of object is stored in the target location.

The object stored in the target location is a Map<String, String>. You can then access its content with ${target.key} or ${target['key']}.

See also Expressions.
"key": configuration expression<string>, required: Name of the element in the target object to contain an extraction result.
"pattern": pattern, required: The regular expression pattern to find in the entity.

See also Patterns.
"template": pattern-template, optional: The template to apply to the pattern, and store in the named target element.

Default: store the match result itself.

See also Patterns.

Examples

Extracts a nonce from the response, which is typically a login page, and sets its value in the attributes context to be used by the downstream filter posting the login form. The nonce value would be accessed using the following expression: ${attributes.extract.wpLoginToken}.

The pattern finds all matches in the HTTP body of the form wpLogintokenvalue="abc". Setting the template to $1 assigns the value abc to attributes.extract.wpLoginToken:

{
    "name": "WikiNoncePageExtract",
    "type": "EntityExtractFilter",
    "config": {
        "messageType": "response",
        "target": "${attributes.extract}",
        "bindings": [
            {
                "key": "wpLoginToken",
                "pattern": "wpLoginToken\"\\s.*value=\"(.*)\"",
                "template": "$1"
            }
        ]
    }
}

The following example reads the response looking for the AM login page. When found, it sets isLoginPage = true to be used in a SwitchFilter to post the login credentials:

{
    "name": "FindLoginPage",
    "type": "EntityExtractFilter",
    "config": {
        "messageType": "response",
        "target": "${attributes.extract}",
        "bindings": [
            {
                "key": "isLoginPage",
                "pattern": "OpenAM\s\(Login\)",
                "template": "true"
            }
        ]
    }
}

FapiInteractionIdFilter

Tracks the interaction ID of requests, according to the Financial-grade API (FAPI) WG, as follows:

If a FAPI header is provided in a client request, includes the interaction ID in the x-fapi-interaction-id property of the response header.
If a FAPI header is not provided in the request, includes a new Universally Unique Identifier (UUID) in the x-fapi-interaction-id property of the response header.
Adds the value of x-fapi-interaction-id to the log.

Usage

{
  "name": string,
  "type": "FapiInteractionIdFilter"
}

Properties

There are no configuration properties for this filter.

Example

The following example, based on Validate Certificate-Bound Access Tokens, adds a FapiInteractionIdFilter to the end of the chain:

{
  "name": "mtls",
  "condition": "${find(request.uri.path, '/mtls')}",
  "handler": {
    "type": "Chain",
    "config": {
      "filters": [ {
          "name": "OAuth2ResourceServerFilter-1",
           ...
        },
        {
          "type": "FapiInteractionIdFilter"
        }
      ],
      "handler": {
          "name": "StaticResponseHandler-1",
          ...
      }
    }
  }
}

FragmentFilter

Tracks the fragment part of a URI when a request triggers a login redirect.

Before authentication, the filter captures the URI fragment information and stores it in a cookie.
After authentication, when the request is issued again to the original URI, the filter redirects the browser to the original URI, including any URI fragment.

Use this filter with SingleSignOnFilter, CrossDomainSingleSignOnFilter, AuthorizationCodeOAuth2ClientFilter, and PolicyEnforcementFilter. This filter is not required for SAML because the final redirect is done with a DispatchHandler and a StaticResponseFilter.

Usage

{
  "name": string,
  "type": "FragmentFilter",
  "config": {
    "fragmentCaptureEndpoint": configuration expression<string>,
    "noJavaScriptMessage": configuration expression<string>,
    "cookie": object
  }
}

"fragmentCaptureEndpoint": configuration expression<string>, required

The IG endpoint used to capture the fragment form data.

Configure the endpoint to match the condition of the route in which the filter is used.

"noJavaScriptMessage": configuration expression<string>, optional

A message to display on the fragment form when JavaScript is not enabled.

Default: No message

"cookie": object, optional

The configuration of the cookie used to store the fragment information.

{
  "name": configuration expression<string>,
  "domain": configuration expression<string>,
  "httpOnly": configuration expression<boolean>,
  "path": configuration expression<string>,
  "sameSite": configuration expression<enumeration>,
  "secure": configuration expression<boolean>,
  "maxAge": configuration expression<duration>
}

"name": configuration expression<string>, optional: Cookie name.

Default: ig-fragment-cookie

"domain": configuration expression<string>, optional

Domain to which the cookie applies.

Default: The fully qualified hostname of the IG host.

"httpOnly": configuration expression<boolean>, optional

Flag to mitigate the risk of client-side scripts accessing protected cookies.

Default: true

"path": configuration expression<string>, optional

Path to apply to the cookie.

Default: /

"sameSite": configuration expression<enumeration>, optional

Options to manage the circumstances in which a cookie is sent to the server. Use one of the following values to reduce the risk of CSRF attacks:

STRICT: Send the cookie only if the request was initiated from the cookie domain. Not case-sensitive.

Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
LAX: Send the cookie only with GET requests in a first-party context, where the URL in the address bar matches the cookie domain. Not case-sensitive.

Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
NONE: Send the cookie whenever a request is made to the cookie domain. Not case-sensitive.

With this setting, consider setting secure to true to prevent browsers from rejecting the cookie. For more information, refer to SameSite cookies.

Default: LAX

"secure": configuration expression<boolean>, optional

Flag to limit the scope of the cookie to secure channels.

Default: false

"maxAge": configuration expression<duration>, optional

The maximum duration for which the FragmentFilter cookie can be valid.

When this maxAge is greater than the browser’s maximum internal value, the browser value takes precedence.

Default: 1 hour

Example

For an example of how the FragmentFilter is used in an SSO flow, refer to URI fragments in redirect.

FileAttributesFilter

Retrieves and exposes a record from a delimiter-separated file. Lookup of the record is performed using a specified key, whose value is derived from an expression. The resulting record is exposed in an object whose location is specified by the target expression. If a matching record cannot be found, then the resulting object is empty.

The retrieval of the record is performed lazily; it does not occur until the first attempt to access a value in the target. This defers the overhead of file operations and text processing until a value is first required. This also means that the value expression is not evaluated until the object is first accessed.

Usage

{
     "name": string,
     "type": "FileAttributesFilter",
     "config": {
         "file": configuration expression<string>,
         "charset": configuration expression<string>,
         "separator": configuration expression<enumeration>,
         "header": configuration expression<boolean>,
         "fields": [ configuration expression<string>, ... ],
         "target": lvalue-expression,
         "key": configuration expression<string>,
         "value": runtime expression<string>
     }
}

For an example, refer to Password replay from a file.

Properties

"file": configuration expression<string>, required

The file containing the record to be read.

"charset": configuration expression<string>, optional

The character set in which the file is encoded.

Default: "UTF-8".

"separator": configuration expression<enumeration>, optional

The separator character, which is one of the following:

COLON: Unix-style colon-separated values, with backslash as the escape character.
COMMA: Comma-separated values, with support for quoted literal strings.
TAB: Tab-separated values, with support for quoted literal strings.

Default: COMMA

"header": configuration expression<boolean>,optional

A flag to treat the first row of the file as a header row.

When the first row of the file is treated as a header row, the data in that row is disregarded and cannot be returned by a lookup operation.

Default: true.

"fields": array of configuration expression<strings>, optional

A list of keys in the order they appear in a record.

If fields is not set, the keys are assigned automatically by the column numbers of the file.

"target": <lvalue-expression>, required

Expression that yields the target object to contain the record.

The target object is a Map<String, String>, where the fields are the keys. For example, if the target is ${attributes.file} and the record has a username field and a password field mentioned in the fields list, Then you can access the user name as ${attributes.file.username} and the password as ${attributes.file.password}.

See also Expressions.

"key": configuration expression<string>, required

The key used for the lookup operation.

"value": runtime expression<string>, required

The value to be looked-up in the file.

See also Expressions.

ForwardedRequestFilter

Rebase the request URI to a computed scheme, host name, and port.

Use this filter to configure redirects when a request is forwarded by an upstream application such as a TLS offloader.

Usage

{
  "name": string,
  "type": "ForwardedRequestFilter",
  "config": {
    "scheme": runtime expression<string>,
    "host": runtime expression<string>,
    "port": runtime expression<number>
  }
}

Properties

At least one of scheme, host, or port must be configured.

"scheme": runtime expression<string>, optional: The scheme to which the request is rebased, for example, https.

Default: Not rebased to a different scheme
"host": runtime expression<string>, optional: The host to which the request is rebased.

Default: Not rebased to a different host
"port": runtime expression<number>, optional: The port to which the request is rebased.

Default: Not rebased to a different port

Example

In the following configuration, IG runs behind an AWS load balancer, to perform a login page redirect to an authentication party, using the original URI requested by the client.

IG can access the URI used by the load balancer to reach IG, but can’t access the original request URI.

The load balancer breaks the original request URI into the following headers, and adds them to the incoming request:

X-Forwarded-Proto: Scheme
X-Forwarded-Port: Port
Host: Original host name, and possibly the port.

{
  "type": "ForwardedRequestFilter",
  "config": {
    "scheme": "${request.headers['X-Forwarded-Proto'][0]}",
    "host": "${split(request.headers['Host'][0], ':')[0]}",
    "port": "${integer(request.headers['X-Forwarded-Port'][0])}"
  }
}

HeaderFilter

Removes headers from and adds headers to request and response messages. Headers are added to any existing headers in the message. To replace a header, remove the header and then add it again.

Usage

{
  "name": string,
  "type": "HeaderFilter",
  "config": {
    "messageType": configuration expression<enumeration>,
    "remove": [ configuration expression<string>, ... ],
    "add": {
      string: [ runtime expression<string>, ... ], ...
    }
  }
}

Properties

`"messageType": configuration expression<enumeration>, required

The type of message for which to filter headers. Must be either "REQUEST" or "RESPONSE".

"remove": array of configuration expression<strings>, optional

The names of header fields to remove from the message.

"add": object, optional

One or more headers to add to a request, with the format name: [ value, … ], where:

name is a string for a header name.
value is a runtime expression that resolves to one or more header values.

Examples

Replace host header on an incoming request

The following example replaces the host header on the incoming request with the value myhost.com:

{
  "name": "ReplaceHostFilter",
  "type": "HeaderFilter",
  "config": {
    "messageType": "REQUEST",
    "remove": [ "host" ],
    "add": {
      "host": [ "myhost.com" ]
    }
  }
}

The following example adds a Set-Cookie header to the response:

{
  "name": "SetCookieFilter",
  "type": "HeaderFilter",
  "config": {
    "messageType": "RESPONSE",
    "add": {
      "Set-Cookie": [ "mysession=12345" ]
    }
  }
}

Add headers to a request

The following example adds the headers custom1 and custom2 to the request:

{
  "name": "SetCustomHeaders",
  "type": "HeaderFilter",
  "config": {
    "messageType": "REQUEST",
    "add": {
      "custom1": [ "12345", "6789" ],
      "custom2": [ "abcd" ]
    }
  }
}

Add a token value to a response

The following example adds the value of session’s policy enforcement token to the pef_sso_token header in the response:

{
  "type": "HeaderFilter",
  "config": {
    "messageType": "RESPONSE",
    "add": {
      "pef_sso_token": ["${session.pef_token}"]
    }
  }
}

Add headers and logging results

The following example adds a message to the request and response as it passes through the Chain, and the capture on the ReverseProxyHandler logs the result. With IG and the sample application set up as described in the Getting started, access this route on http://ig.example.com:8080/home/chain.

{
  "condition": "${find(request.uri.path, '^/home/chain')}",
  "handler": {
    "type": "Chain",
    "comment": "Base configuration defines the capture decorator",
    "config": {
      "filters": [
        {
          "type": "HeaderFilter",
          "comment": "Add a header to all requests",
          "config": {
            "messageType": "REQUEST",
            "add": {
              "MyHeaderFilter_request": [
                "Added by HeaderFilter to request"
              ]
            }
          }
        },
        {
          "type": "HeaderFilter",
          "comment": "Add a header to all responses",
          "config": {
            "messageType": "RESPONSE",
            "add": {
              "MyHeaderFilter_response": [
                "Added by HeaderFilter to response"
              ]
            }
          }
        }
      ],
      "handler": {
        "type": "ReverseProxyHandler",
        "comment": "Log request, pass it to the sample app, log response",
        "capture": "all",
        "baseURI": "http://app.example.com:8081"
      }
    }
  }
}

The chain receives the request and context and processes it as follows:

The first HeaderFilter adds a header to the incoming request.
The second HeaderFilter manages responses not requests, so it simply passes the request and context to the handler.
The ReverseProxyHandler captures (logs) the request.
The ReverseProxyHandler forwards the transformed request to the protected application.
The protected application passes a response to the ReverseProxyHandler.
The ReverseProxyHandler captures (logs) the response.
The second HeaderFilter adds a header added to the response.
The first HeaderFilter is configured to manage requests, not responses, so it simply passes the response back to IG.

The following example lists some of the HTTP requests and responses captured as they flow through the chain. You can search the log files for MyHeaderFilter_request and MyHeaderFilter_response.

# Original request from user-agent
GET http://ig.example.com:8080/home/chain HTTP/1.1
Accept: /
Host: ig.example.com:8080

# Add a header to the request (inside IG) and direct it to the protected application
GET http://app.example.com:8081/home/chain HTTP/1.1
Accept: /
Host: ig.example.com:8080
MyHeaderFilter_request: Added by HeaderFilter to request

# Return the response to the user-agent
HTTP/1.1 200 OK
Content-Length: 1809
Content-Type: text/html; charset=ISO-8859-1

# Add a header to the response (inside IG)
HTTP/1.1 200 OK
Content-Length: 1809
MyHeaderFilter_response: Added by HeaderFilter to response

HttpBasicAuthenticationClientFilter

Authenticates clients according to the HTTP basic access authentication scheme.

HTTP basic access authentication is a simple challenge and response mechanism, where a server requests credentials from a client, and the client passes them to the server in an Authorization header. The credentials are base-64 encoded. To protect them, use SSL encryption for the connections between the server and client. For more information, see RFC 2617.

Compare the purpose of this filter with that of the following filters:

ClientCredentialsOAuth2ClientFilter, which authenticates clients by their OAuth 2.0 credentials to obtain an access token from an authorization server.
ClientSecretBasicAuthenticationFilter, which fulfils the same role of transforming OAuth 2.0 credentials to an Authorization header, but is more strict for OAuth 2.0 requirements.

Use HttpBasicAuthenticationClientFilter in a service-to-service context, where services need to access resources protected by HTTP basic access authentication.

Usage

{
  "name": string,
  "type": "HttpBasicAuthenticationClientFilter",
  "config": {
    "username": configuration expression<string>,
    "passwordSecretId": configuration expression<secret-id>,
    "secretsProvider": SecretsProvider reference,
    "urlEncodeCredentials": configuration expression<boolean>
  }
}

Properties

"username": configuration expression<string>, required: The username of the client to authenticate.
"passwordSecretId": configuration expression<string>, required: The secret ID required to obtain the client password.

This secret ID must point to a GenericSecret.
"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to obtain the passwordSecretId. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.
"urlEncodeCredentials": configuration expression<boolean>, optional: Set to true to URL-encoded credentials before base64-encoding them.

Default: false

Example

The following example shows the flow of information when a client service accesses a resource protected by HTTP basic access authentication:

Set Up the Example

Note the following features of the route:

The route matches requests to /http-basic-access.
The ScriptableHandler rewrites the request to target it to /http-basic-protected-resource, and then calls the HTTP client, that has been redefined to use the httpBasicAuthEnabledClientHandler.
The httpBasicAuthEnabledClientHandler calls the HttpBasicAuthenticationClientFilter to authenticate the client, using the client’s credentials.

          },
          "entity": "<html><body><h2>Access Granted</h2></body></html>"
        }
      }
    }
  }
}

Notice the following features of the route:

The route matches requests to /http-basic-protected-resource.
The ScriptableFilter provides a script to implement a simple HTTP basic access authentication scheme, that compares the provided credentials with the expected credentials.
When the client is authenticated, the StaticResponseHandler returns a message that access is granted.

Access the route on http://ig.example.com:8080/http-basic-access.

Because the expected credentials were provided in the request, a message shows that access is granted.

HttpBasicAuthFilter

Authenticate clients by providing the client credentials as a basic authorization header in the request. The credentials are base64-encoded.

This filter performs HTTP basic access authentication, described in RFC 2617.

Use this filter primarily for password replay scenarios, where the password is stored externally in clear text.

If challenged for authentication via a 401 Unauthorized status code by the server, this filter retries the request with credentials attached. After an HTTP authentication challenge is issued from the remote server, all subsequent requests to that remote server that pass through the filter include the user credentials.

If authentication fails (including the case where no credentials are yielded from expressions), then processing is diverted to the specified authentication failure handler.

Usage

{
    "name": string,
    "type": "HttpBasicAuthFilter",
    "config": {
        "username": runtime expression<string>,
        "password": runtime expression<string>,
        "failureHandler": Handler reference,
        "cacheHeader": configuration expression<boolean>
    }
}

Properties

"username": runtime expression<string>, required: The username to supply during authentication.

See also Expressions.
"password": runtime expression<string>, required: The password to supply during authentication.

See also Expressions.
"failureHandler": Handler reference, required: Dispatch to this Handler if authentication fails.

Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.

See also Handlers.
"cacheHeader": configuration expression<boolean>,optional: Whether or not to cache credentials in the session after the first successful authentication, and then replay those credentials for subsequent authentications in the same session.

With "cacheHeader": false, the filter generates the header for each request. This is useful, for example, when users change their passwords during a browser session.

Default: true

Example

{
    "name": "MyAuthenticator",
    "type": "HttpBasicAuthFilter",
    "config": {
        "username": "demo",
        "password": "password",
        "failureHandler": "AuthFailureHandler",
        "cacheHeader": false
    }
}

IdTokenValidationFilter

Validates an ID token by checking the standard claims, aud, exp, and iat. If specified in the configuration, this filter also checks the ID token issuer and signature.

This filter passes data into the context as follows:

If the JWT is validated, the request continues down the chain. The data is provided in the JwtValidationContext.
If the JWT is not validated, data is provided in the JwtValidationErrorContext.

If a failure handler is configured, the request passes to the failure handler. Otherwise, an HTTP 403 Forbidden is returned.

The iat claim is required, and the iat minus the skewAllowance must be before the current time on the IG clock. For information, see OpenID Connect Core 1.0 incorporating errata set 1.

Usage

{
   "name": string,
   "type": "IdTokenValidationFilter",
   "config": {
     "idToken": runtime expression<string>,
     "audience": configuration expression<string>,
     "issuer": configuration expression<string>,
     "skewAllowance": configuration expression<duration>,
     "verificationSecretId": configuration expression<secret-id>,
     "secretsProvider": SecretsProvider reference,
     "customizer": JwtValidatorCustomizer reference,
     "failureHandler": Handler reference
   }
}

Properties

"idToken": runtime expression<string>, required: The ID token as an expression representing the JWT or signed JWT in the request. Cannot be null.
"audience": configuration expression<string>, required: One aud claim to check on the JWT. Cannot be null.
"issuer": configuration expression<string>, optional: One iss claim to check on the JWT. Can be null.

"skewAllowance": configuration expression<duration>, optional

The duration to add to the validity period of a JWT to allow for clock skew between different servers. To support a zero-trust policy, the skew allowance is by default zero.

A skewAllowance of 2 minutes affects the validity period as follows:

A JWT with an iat of 12:00 is valid from 11:58 on the IG clock.
A JWT with an exp 13:00 is expired after 13:02 on the IG clock.

Default: zero

"verificationSecretId": configuration expression<secret-id>, required to verify the signature of signed tokens: The secret ID for the secret to verify the signature of signed tokens.

This secret ID must point to a CryptoKey.

If configured, the token must be signed. If not configured, IG does not verify the signature.

For information about how signatures are validated, refer to Validating the signature of signed tokens. For information about how each type of secret store resolves named secrets, refer to Secrets.

"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.

"customizer": JwtValidatorCustomizer reference, optional

A set of validation constraints for JWT claims and sub-claims. If a claim is not validated against the constraint, the JWT is not validated.

The customizer does not override existing constraints, such as aud, iss, exp, and iat, which are predefined in the IdTokenValidationFilter, Defining a new constraint on an already constrained claim has an impact only if the new constraint is more restrictive.

JwtValidatorCustomizer provides a ScriptableJwtValidatorCustomizer to enrich a builder object by using its methods. Get more information about the following items:

Add the following route to IG:

Linux
Windows

$HOME/.openig/config/routes/idtokenvalidation.json

        }
      }
    }
  }
}

Notice the following features of the route:

The route matches requests to /idtokenvalidation.
A SecretsProvider declares a JwkSetSecretStore to validate secrets for signed JWTs, which specifies the URL to a JWK set on AM that contains the signing keys.
The property verificationSecretId is configured with a value. If this property is not configured, the filter does not verify the signature of tokens.
The JwkSetSecretStore specifies the URL to a JWK set on AM, that contains signing keys identified by a kid. The signature of the token is verified as follows:
- If the value of a kid in the JWK set matches a kid in the the signed JWT, the JwkSetSecretStore verifies the signature.
- If the JWT doesn’t have a kid, or if the JWK set doesn’t contain a key with the same value, the JwkSetSecretStore looks for valid secrets with the same purpose as the value of verificationSecretId.
If the filter validates the token, the StaticResponseHandler displays the token value from the context ${contexts.jwtValidation.value}. Otherwise, the ScriptableHandler displays the token value and a list of violations from the context ${contexts.jwtValidationError.violations}

Test the setup:
1. In a terminal window, use a curl command similar to the following to retrieve an id_token:
  $ curl -s \ --user "client-application:password" \ --data "grant_type=password&username=demo&password=Ch4ng31t&scope=openid" \ http://am.example.com:8088/openam/oauth2/access_token { "access_token":"...", "scope":"openid", "id_token":"...", "token_type":"Bearer", "expires_in":3599 }
  - In the route, replace <id_token_value> with the value of the id_token returned in the previous step.
2. Access the route on http://ig.example.com:8080/idtokenvalidation.
  
  The validated token is displayed.
  - In the route, invalidate the token by changing the value of the audience or issuer, and then access the route again.
    
    The value of the token, and the reasons that the token is invalid, are displayed.

JwtBuilderFilter

Collects data at runtime, packs it in a JSON Web Token (JWT), and places the resulting JWT into the JwtBuilderContext.

Configure JwtBuilderFilter to create an unsigned JWT, a signed JWT, a signed then encrypted JWT, or an encrypted JTW:

Sign the JWT so that an application can validate the authenticity of the claims/data. The JWT can be signed with a shared secret or private key, and verified with a shared secret or corresponding public key.
Encrypt the JWT to reduce the risk of a data breach.

For a flexible way to pass identity or other runtime information to the protected application, use this filter with a HeaderFilter.

To enable downstream filters and handlers to verify signed and/or encrypted JWTs built by this filter, use this filter with a JwkSetHandler.

Usage

{
  "name": string,
  "type": "JwtBuilderFilter",
  "config": {
    "template": map or runtime expression<map>,
    "secretsProvider": SecretsProvider reference,
    "signature": object,
    "encryption": object
  }
}

Properties

"template": map or runtime expression<map>, required

A map of one or more data pairs with the format Map<String, Object>, where:

The key is the name of a data field
The value is a data object, or a runtime expression that evaluates to a data object

The following formats are allowed:

{
  "template": {
    "string": "runtime expression<object>",
    ...
  }
}

{
  "template": "runtime expression<map>"
}

In the following example, the property is a map whose values are runtime expressions that evaluate to objects in the context:

{
  "template": {

    "address": "${contexts.userProfile.rawInfo.postalAddress[0]}",
    "phone": "${contexts.userProfile.rawInfo.telephoneNumber[0]}"
  }
}

In the following example, the property is a runtime expression that evaluates to a map with the format Map<String, Object>:

{
  "template": "${contexts.attributes}"
}

Use the now dynamic binding to dynamically set the value of an attribute that represents time. For example, set the value of attributes to a defined time after the expressions are evaluated, as follows:

LocationHeaderFilter

For a response that generates a redirect to the proxied application, this filter rewrites the Location header on the response to redirect the user to IG.

Usage

{
    "name": string,
    "type": "LocationHeaderFilter",
    "config": {
        "baseURI": runtime expression<url>
    }
}

An alternative value for type is RedirectFilter.

Properties

"baseURI": runtime expression<url>,optional: The base URI of the IG instance. This is used to rewrite the Location header on the response.

The result of the expression must be a string that represents a valid URI, but is not a real java.net.URI object. For example, it would be incorrect to use ${request.uri}, which is not a String but a MutableUri.

Default: Redirect to the original URI specified in the request.

See also Expressions.

Example

In the following example, IG listens on https://ig.example.com:443 and the application it protects listens on http://app.example.com:8081. The filter rewrites redirects that would normally take the user to locations under http://app.example.com:8081 to go instead to locations under https://ig.example.com:443.

{
     "name": "LocationRewriter",
     "type": "LocationHeaderFilter",
     "config": {
         "baseURI": "https://ig.example.com:443/"
      }
}

OAuth2ClientFilter

In IG 7.2, this filter was renamed to AuthorizationCodeOAuth2ClientFilter.

For backward compatibility, the name OAuth2ClientFilter can still be used in routes in this release. However, to prevent problems in future releases, update your configuration as soon as possible.

OAuth2ResourceServerFilter

Validates a request containing an OAuth 2.0 access token. The filter expects an OAuth 2.0 token from the HTTP Authorization header of the request, such as the following example header, where the OAuth 2.0 access token is 1fc…ec9:

Authorization: Bearer 1fc...ec9

The filter performs the following tasks:

Extracts the access token from the request header.
Uses the configured access token resolver to resolve the access token against an authorization server, and validate the token claims.
Checks that the token has the scopes required by the filter configuration.
Injects the access token info into the OAuth2Context.

The following errors can occur during access token validation:

Error Response from the filter to the user agent

Error	Response from the filter to the user agent
Combination of the filter configuration and access token result in an invalid request to the authorization server.	`HTTP 400 Bad Request`
There is no access token in the request header.	`HTTP 401 Unauthorized WWW-Authenticate: Bearer realm="IG"`
The access token isn’t valid, for example, because it has expired.	`HTTP 401 Unauthorized`
The access token doesn’t have all of the scopes required in the OAuth2ResourceServerFilter configuration.	`HTTP 403 Forbidden`

Combination of the filter configuration and access token result in an invalid request to the authorization server.

HTTP 400 Bad Request

There is no access token in the request header.

HTTP 401 Unauthorized WWW-Authenticate: Bearer realm="IG"

The access token isn’t valid, for example, because it has expired.

HTTP 401 Unauthorized

The access token doesn’t have all of the scopes required in the OAuth2ResourceServerFilter configuration.

HTTP 403 Forbidden

Usage

{
  "name": string,
  "type": "OAuth2ResourceServerFilter",
  "config": {
    "accessTokenResolver": AccessTokenResolver reference,
    "cache": object,
    "executor": Executor service reference,
    "requireHttps": configuration expression<boolean>,
    "realm": configuration expression<string>,
    "scopes": [ runtime expression<string>, ... ] or ScriptableResourceAccess reference
  }
}

An alternative value for type is OAuth2RSFilter.

Properties

"accessTokenResolver": AccessTokenResolver reference, required

Resolves an access token against an authorization server. Configure one of the following access token resolvers:

To decorate an AccessTokenResolver, add the decoration at the accessTokenResolver level. The following example uses the default timer decorator to record the time that a TokenIntrospectionAccessTokenResolver takes to process a request:

{
  "accessTokenResolver": {
    "type": "TokenIntrospectionAccessTokenResolver",
    "config": {
      ...
    },
  "timer": true
  }
}

"cache": object, optional

Configuration of caching for OAuth 2.0 access tokens. By default, access tokens are not cached. For an alternative way of caching of OAuth 2.0 access tokens, configure CacheAccessTokenResolver.

When an access token is cached, IG can reuse the token information without repeatedly asking the authorization server to verify the access token. When caching is disabled, IG must ask the authorization server to verify the access token for each request.

(From AM 6.5.3.) When an access_token is revoked on AM, the CacheAccessTokenResolver can delete the token from the cache when both of the following conditions are true:

The notification property of AmService is enabled.
The delegate AccessTokenResolver provides the token metadata required to update the cache.

When a refresh_token is revoked on AM, all associated access tokens are automatically and immediately revoked.

"cache": {
  "enabled": configuration expression<boolean>,
  "defaultTimeout": configuration expression<duration>,
  "maxTimeout": configuration expression<duration>,
  "amService": AmService reference,
  "onNotificationDisconnection": configuration expression<enumeration>
}

enabled: configuration expression<boolean>, optional

Enable or disable caching.

Default: false

defaultTimeout: configuration expression<duration>, optional

The duration for which to cache an OAuth 2.0 access token if it doesn’t provide a valid expiry value.

If an access token provides an expiry value that falls before the current time plus the maxTimeout, IG uses the token expiry value.

The following example caches access tokens for these times:

One hour, if the access token doesn’t provide a valid expiry value.
The duration specified by the token expiry value, when the token expiry value is shorter than one day.
One day, when the token expiry value is longer than one day.

"cache": {
  "enabled": true,
  "defaultTimeout": "1 hour",
  "maxTimeout": "1 day"
}

Default: 1 minute

maxTimeout: configuration expression<duration>, optional

The maximum duration for which to cache OAuth 2.0 access tokens.

If an access token provides an expiry value that falls after the current time plus the maxTimeout, IG uses the maxTimeout.

The duration cannot be zero or unlimited.

"amService": AmService reference, optional

(From AM 6.5.3.) The AmService to use for the WebSocket notification service. To evict revoked access tokens from the cache, enable the notifications property of AmService.

onNotificationDisconnection: configuration expression<enumeration>, optional

An amService must be configured for this property to have effect.

The strategy to manage the cache when the WebSocket notification service is disconnected, and IG receives no notifications for AM events. If the cache is not cleared it can become outdated, and IG can allow requests on revoked sessions or tokens.

Cached entries that expire naturally while the notification service is disconnected are removed from the cache.

Use one of the following values:

NEVER_CLEAR
- When the notification service is disconnected:
  - Continue to use the existing cache.
  - Deny access for requests that are not cached, but do not update the cache with these requests.
- When the notification service is reconnected:
  - Continue to use the existing cache.
  - Query AM for incoming requests that are not found in the cache, and update the cache with these requests.
CLEAR_ON_DISCONNECT
- When the notification service is disconnected:
  - Clear the cache.
  - Deny access to all requests, but do not update the cache with these requests.
- When the notification service is reconnected:
  - Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
  - Update the cache with these requests.
CLEAR_ON_RECONNECT
- When the notification service is disconnected:
  - Continue to use the existing cache.
  - Deny access for requests that are not cached, but do not update the cache with these requests.
- When the notification service is reconnected:
  - Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
  - Update the cache with these requests.

Default: CLEAR_ON_DISCONNECT

"executor": Executor service reference, optional

An executor service to schedule the execution of tasks, such as the eviction of entries in the access token cache.

Default: ScheduledExecutorService

OAuth2TokenExchangeFilter

Identifies a client’s access token or ID token (a subject token), and communicates with an authorization service, such as AM, to exchange it for a new token (an issued token):

When the OAuth2TokenExchangeFilter succesfully exchanges a token, it injects the issued token and its scopes into the OAuth2TokenExchangeContext.
When the OAuth2TokenExchangeFilter fails to exchange a token, it injects information about the failure into the OAuth2FailureContext, which is provided to the failureHandler.

The scopes for issued token can be restricted or expanded by the authorization services:

Restricted when the token scopes are a subset of those available to the subject token.
Expanded when they have scopes that are not included in the subject token.

Use this filter in the impersonation use case. For more information, refer to OAuth 2.0 Token Exchange in AM’s OAuth 2.0 guide.

PasswordReplayFilter

Extracts credentials from AM and replays them to a login page or to the next filter or handler in the chain. The PasswordReplayFilter does not retry failed authentication attempts.

The PasswordReplayFilter filter uses the AM Post Authentication Plugin com.sun.identity.authentication.spi.JwtReplayPassword. The plugin is triggered for AM authentication chains but not currently for AM authentication trees.

Do not use the PasswordReplayFilter with AM authentication trees.

Usage

{
  "name": string,
  "type": "PasswordReplayFilter",
  "config": {
    "request": object,
    "loginPage": runtime expression<boolean>,
    "loginPageContentMarker": pattern,
    "credentials": Filter reference,
    "headerDecryption": object,
    "loginPageExtractions": [ object, ... ]
  }
}

Properties

"request": <object>, required

The HTTP request message that replays the credentials.

{
  "request": object,
    "method": config expression<string>,
    "uri": runtime expression<string>,
    "version": configuration expression<string>,
    "entity": runtime expression<string>,
    "headers": map,
    "form": map
}

For information about the properties of `request`refer to Request.

The JSON object of request is the config content of a StaticRequestFilter.

"loginPage": runtime expression<boolean>, required unless loginPageContentMarker is defined

true: Direct the request to a login page, extract credentials, and replay them.

false: Pass the request unchanged to the next filter or handler in the chain.

The following example expression resolves to true when the request is an HTTP GET, and the request URI path is /login:

${find(request.uri.path, '/login') and (request.method == 'GET')}

"loginPageContentMarker": pattern, required unless loginPage is defined

A pattern that matches when a response entity is a login page.

For an example route that uses this property, refer to Login form with password replay and cookie filters.

Example

The following example authenticates requests using static credentials when the request URI path is /login. This PasswordReplayFilter example does not include any mechanism for remembering when authentication has already been successful, it simply replays the authentication every time that the request URI path is /login:

{
  "handler": {
    "type": "Chain",
    "config": {
      "filters": [{
        "type": "PasswordReplayFilter",
        "config": {
          "loginPage": "${request.uri.path == '/login'}",
          "request": {
            "method": "POST",
            "uri": "https://www.example.com:8444/login",
            "form": {
              "username": [
                "MY_USERNAME"
              ],
              "password": [
                "MY_PASSWORD"
              ]
            }
          }
        }
      }],
      "handler": "ReverseProxyHandler"
    }
  }
}

For additional examples, refer to Configuration templates, and the Javadoc for the PasswordReplayFilter class.

PolicyEnforcementFilter

Requests policy decisions from AM, which allows or denies the request based on the request context, the request URI, and the AM policies.

Processing requests after a policy decision

After a policy decision, IG continues to process requests as follows:

If the request is allowed, processing continues.
If the request is denied with advices, IG checks whether it can respond to the advices. If IG can respond, it sends a redirect and information about how to meet the conditions in the advices.

By default, the request is redirected to AM. If the SingleSignOnFilter property loginEndpoint is configured, the request is redirected to that endpoint.
If the request is denied without advice, or if IG cannot respond to the advice, IG forwards the request to a failureHandler declared in the PolicyEnforcementFilter. If there is no failureHandler, IG returns a 403 Forbidden.
If an error occurs during the process, IG returns 500 Internal Server Error.

Using advices from policy decisions

Attributes and advices returned by the policy decision are stored in the policyDecision context. For information, refer to PolicyDecisionContext.

IG responds to the following advice types from AM:

AuthLevel: The minimum authentication level at which a user agent must authenticate to access a resource.
AuthenticateToService: The name of an authorization chain or service to which a user agent must authenticate to access a resource.
AuthenticateToRealm: The name of a realm to which a user agent must authenticate to access a resource.
AuthScheme: The name of an authentication module to which a user agent must authenticate to access a resource, the policy set name, and the authentication timeout.
Transaction: The additional actions that a user agent must perform before having a one-time access to the protected resource.

Notes on configuring policies in AM

In the AM policy, remember to configure the Resources parameter with the URI of the protected application.

The request URI from IG must match the Resources parameter defined in the AM policy. If the URI of the incoming request is changed before it enters the policy filter (for example, by rebasing or scripting), remember to change the Resources parameter in AM policy accordingly.

WebSocket notifications for policy changes

When WebSocket notifications are set up for changes to policies, IG receives a notification from AM when a policy decision is created, deleted, or updated.

For information about setting up WebSocket notifications, using them to clear the policy cache, and including them in the server logs, refer to WebSocket Notifications.

Usage

{
  "name": string,
  "type": "PolicyEnforcementFilter",
  "config": {
    "amService": AmService reference,
    "pepRealm": configuration expression<string>,
    "ssoTokenSubject": runtime expression<string>,
    "jwtSubject": runtime expression<string>,
    "claimsSubject": map or runtime expression<map>,
    "cache": object,
    "application": configuration expression<string>,
    "environment": map or runtime expression<map>,
    "failureHandler": Handler reference,
    "resourceUriProvider": ResourceUriProvider reference
  }
}

Properties

"amService": AmService reference, required

The AmService object to use for the following properties:

agent, the credentials of the IG agent in AM. When the agent is authenticated, the token can be used for tasks such as getting the user’s profile, making policy evaluations, and connecting to the AM notification endpoint.
realm: Realm of the IG agent in AM.
url, the URL of an AM service to use for session token validation and authentication.
ssoTokenHeader, the name of the HTTP header that provides the session token created by AM
amHandler, the handler to use when requesting policy decisions from AM.
version: The version of the AM server.

The AM version is derived as follows, in order of precedence:
- Discovered value: AmService discovers the AM version. If version is configured with a different value, AmService ignores the value of version and issues a warning.
- Value in version: AmService cannot discover the AM version, and version is configured.
- Default value of AM 6: AmService cannot discover the AM version, and version is not configured.
See also AmService.

"pepRealm": configuration expression<string>, optional

The AM realm where the policy set is located.

Default: The realm declared for amService.

"ssoTokenSubject": _runtime expression<string>, required if neither of the following properties are present: jwtSubject, claimsSubject

The AM SSO or CDSSO token ID string for the subject making the request to the protected resource.

ssoTokenSubject can take the following values:

${contexts.ssoToken.value}, when the SingleSignOnFilter is used for authentication
${contexts.ssoToken.value} or ${contexts.cdsso.token}, when the CrossDomainSingleSignOnFilter is used for authentication

When there is no SSO (API protection), ssoTokenSubject usually points to a header value such as ${request.headers.iPlanetDirectoryPro[0]}, where iPlanetDirectoryPro is the name of the default AM session cookie. To find the name of your AM session cookie, see Find the name of your AM session cookie.

"jwtSubject": _runtime expression<string>, required if neither of the following properties are present: ssoTokenSubject, claimsSubject

The JWT string for the subject making the request to the protected resource.

To use the raw id_token (base64, not decoded) returned by the OpenID Connect Provider during authentication, place an AuthorizationCodeOAuth2ClientFilter filter before the PEP filter, and then use ${attributes.openid.id_token} as the expression value.

"claimsSubject": map or runtime expression<map>, required if neither of the following properties are present: jwtSubject, `"ssoTokenSubject`

A map of one or more data pairs with the format Map<String, Object>, where:

The key is the name of a claim
The value is a claim object, or a runtime expression that evaluates to a claims object

The following formats are allowed:

{
  "claimsSubject": {
    "string": "runtime expression<object>",
    ...
  }
}

{
  "claimsSubject": "runtime expression<map>"
}

The claim "sub" must be specified; other claims are optional.

In the following example, the property is a map whose first value is a runtime expression that evaluates to a JWT claim for the subject, and whose second value is a JWT claim for the subject:

"claimsSubject": {
  "sub": "${attributes.subject_identifier}",
  "iss": "am.example.com"
}

In the following example, the property is a runtime expression that evaluates to a map with the format Map<String, Object>:

"claimsSubject": "${attributes.openid.id_token_claims}"

For an example that uses claimsSubject as a map, see Example policy enforcement using claimsSubject on this reference page.

"application": configuration expression<string>, optional

The ID of the AM policy set to use when requesting policy decisions.

Default: iPlanetAMWebAgentService, provided by AM’s default policy set

cache: object, optional

Enable and configure caching of policy decisions from AM, based on Caffeine. For more information, see the GitHub entry, Caffeine.

{
  "cache": {
    "enabled": configuration expression<boolean>,
    "defaultTimeout": configuration expression<duration>,
    "executor": Executor service reference,
    "maximumSize": configuration expression<number>,
    "maximumTimeToCache": configuration expression<duration>,
    "onNotificationDisconnection": configuration expression<enumeration>
  }
}

Default: Policy decisions are not cached.

Policy decisions that contain advices are never cached.

The following code example caches AM policy decisions without advices for these times:

One hour, when the policy decision doesn’t provide a ttl value.
The duration specified by the ttl, when ttl is shorter than one day.
One day, when ttl is longer than one day.

"cache": {
  "enabled": true,
  "defaultTimeout": "1 hour",
  "maximumTimeToCache": "1 day"
}

enabled: configuration expression<boolean>, optional

Enable or disable caching of policy decisions.

When a policy decision is cached, IG can reuse the policy decision without repeatedly asking AM for a new policy decision. When caching is disabled, IG must ask AM to make a decision for each request.

Default: false

defaultTimeout: configuration expression<duration>, optional

The default duration for which to cache AM policy decisions.

If an AM policy decision provides a valid ttl value to specify the time until which the policy decision remains valid, IG uses that value or the maxTimeout.

Default: 1 minute

"executor": Executor service reference, optional

An executor service to schedule the execution of tasks, such as the eviction of entries in the cache.

Default: ForkJoinPool.commonPool()

"maximumSize": configuration expression<number>, optional

The maximum number of entries the cache can contain.

Default: Unlimited/unbound.

maximumTimeToCache: configuration expression<duration>, optional

The maximum duration for which to cache AM policy decisions.

If the ttl value provided by the AM policy decision is after the current time plus the maximumTimeToCache, IG uses the maximumTimeToCache.

The duration cannot be zero or unlimited.

onNotificationDisconnection: configuration expression<enumeration>, optional

Cached entries that expire naturally while the notification service is disconnected are removed from the cache.

Use one of the following values:

NEVER_CLEAR
- When the notification service is disconnected:
  - Continue to use the existing cache.
  - Deny access for requests that are not cached, but do not update the cache with these requests.
- When the notification service is reconnected:
  - Continue to use the existing cache.
  - Query AM for incoming requests that are not found in the cache, and update the cache with these requests.
CLEAR_ON_DISCONNECT
- When the notification service is disconnected:
  - Clear the cache.
  - Deny access to all requests, but do not update the cache with these requests.
- When the notification service is reconnected:
  - Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
  - Update the cache with these requests.
CLEAR_ON_RECONNECT
- When the notification service is disconnected:
  - Continue to use the existing cache.
  - Deny access for requests that are not cached, but do not update the cache with these requests.
- When the notification service is reconnected:
  - Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
  - Update the cache with these requests.

Default: CLEAR_ON_DISCONNECT

"environment": map or runtime expression<map>, optional

A map of one or more data pairs with the format Map<String, Object>, where:

The key is the name of a field in the request environment or context, such as a request header
The value is the object to forward to AM with a policy decision request, or a runtime expression that evaluates to the object

The following formats are allowed:

{
  "claimsSubject": {
    "string": "runtime expression<object>",
    ...
  }
}

{
  "claimsSubject": "runtime expression<map>"
}

AM uses environment conditions to set the circumstances under which a policy applies. For example, environment conditions can specify that the policy applies only during working hours or only when accessing from a specific IP address.

Forward any HTTP header or any value that the AM policy definition can use.

In the following example, the property is a map whose values are runtime expressions that evaluate to request headers, an ID token, and the IP address of the subject making the request:

"environment": {
  "H-Via": "${request.headers['Via']}",
  "H-X-Forwarded-For": "${request.headers['X-Forwarded-For']}",
  "H-myHeader": "${request.headers['myHeader']}",
  "id_token": [
    "${attributes.openid.id_token}"
  ],
  "IP": [
    "${contexts.client.remoteAddress}"
  ]
}

"failureHandler": Handler reference, optional

Handler to treat the request if it is denied by the policy decision.

In the following example, the failureHandler is a chain with a scriptable filter. If there are some advices with the policy decision, the script recovers the advices for processing. Otherwise, it passes the request to the StaticResponseHandler to display a message.

"failureHandler": {
  "type": "Chain",
  "config": {
    "filters": [
      {
        "type": "ScriptableFilter",
        "config": {
          "type": "application/x-groovy",
          "source": [
            "if (contexts.policyDecision.advices['MyCustomAdvice'] != null) {",
            "  return handleCustomAdvice(context, request)",
            "} else {",
            "  return next.handle(context, request)",
            "}"
          ]
        }
      }
    ],
    "handler": {
      "type": "StaticResponseHandler",
      "config": {
        "status": 403,
        "headers": {
          "Content-Type": [ "text/plain; charset=UTF-8" ]
        },
        "entity": "Restricted area. You do not have sufficient privileges."
      }
    }
  }
}

Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.

Default: HTTP 403 Forbidden, the request stops being executed.

"resourceUriProvider": ResourceUriProvider reference, optional

Return the resource URL to include in policy decision requests to AM. Configure one of the following ResourceUriProviders inline or in the heap:

RequestResourceUriProvider
ScriptableResourceUriProvider

Default: RequestResourceUriProvider

RequestResourceUriProvider

Return a resource URL to include in policy decision requests to AM, by using the original URI of the request or the baseURI of the route.

"resourceUriProvider": {
  "type": "RequestResourceUriProvider",
  "config": {
    "useOriginalUri": configuration expression<boolean>,
    "includeQueryParams": configuration expression<boolean>
  }
}

useOriginalUri: configuration expression<boolean>, optional

A flag to use the original URI of the request as the resource URL in policy decision requests to AM.

true: Use the original URI of the request as the resource URL when requesting policy decisions from AM.
false: Use the baseURI of the route as the resource URL when requesting policy decisions from AM.

Default: false

includeQueryParams: configuration expression<boolean>, optional

A flag to include query parameters in the resource URL when requesting policy decisions from AM:

true: Include query parameters in the resource URL. For example, use the following URL with a query parameter: http://ig.example.com:8080/login?demo=capture.
false: Exclude query parameters from the resource URL. For example, exclude the query parameter from the previous example: http://ig.example.com:8080/login.

For AM policies that specify resource URLs without query parameters, use this option to reduce the amount of cached information.

Default: true

ScriptableResourceUriProvider

Use a script to return a resource URL to include in policy decision requests to AM. The result of the script must be a string that represents the resource URL.

"resourceUriProvider": {
  "type": "ScriptableResourceUriProvider",
  "config": {
    "type": configuration expression<string>,
    "file": configuration expression<string>, // Use either "file"
    "source": [ string, ... ],                // or "source", but not both.
    "args": object,
    "clientHandler": Handler reference
  }
}

For information about these properties, see Scripts.

The following example script replaces existing query parameters with a single parameter:

"resourceUriProvider": {
  "type": "ScriptableResourceUriProvider",
  "config": {
    "type": "application/x-groovy",
    "source": [
      "request.uri.setQuery('fromIG=true')",
      "return request.uri.toASCIIString()"
    ]
  }
}

Example policy enforcement using claimsSubject

This route is a variant of the route in Enforce AM policy decisions in the same domain. It enforces a policy decision from AM, using claimsSubject instead of ssoTokenSubject to identify the subject.

To use this route:

Set up AM as described in Enforce AM policy decisions in the same domain.
In AM, select the policy you created in the previous step, and add a new resource:
- Resource Type: URL
- Resource pattern: *://*:*/*
- Resource value: http://app.example.com:8081/home/pep-claims
In the same policy, add the following subject condition:
- Any of
- Type : OpenID Connect/JwtClaim
- claimName : iss
- claimValue : am.example.com
Set an environment variable for the IG agent password, and then restart IG:
```
$ export AGENT_SECRET_ID='cGFzc3dvcmQ='
```
The password is retrieved by a SystemAndEnvSecretStore, and must be base64-encoded.

Add the following route to serve static resources, such as .css, for the sample application:

Linux
Windows

$HOME/.openig/config/routes/static-resources.json

appdata\OpenIG\config\routes\static-resources.json

{

AM’s Authorization guide

PrivateKeyJwtClientAuthenticationFilter

Supports client authentication with the private_key_jwt client-assertion, using an unencrypted JWT.

Clients send a signed JWT to the authorization server. IG builds and signs the JWT, and prepares the request as in the following example:

POST /token HTTP/1.1
Host: as.example.com
Content-Type: application/x-www-form-urlencoded

grant_type=authorization_code&
code=...&

ResourceOwnerOAuth2ClientFilter

This filter uses the Resource Owner Password Credentials grant type. According to information in the The OAuth 2.0 Authorization Framework, minimize use of this grant type and utilize other grant types whenever possible. Use this filter in a service-to-service context, where services need to access resources protected by OAuth 2.0.

Authenticates OAuth 2.0 clients by using the resource owner’s OAuth 2.0 credentials to obtain an access token from an authorization server, and injecting the access token into the inbound request as a Bearer Authorization header.

Client authentication is provided by the endpointHandler property, which uses a client authentication filter.

The ResourceOwnerOAuth2ClientFilter refreshes the access token as required.

ScriptableFilter

Processes requests and responses by executing a Groovy script. Executed scripts must return one of the following:

To execute the next element in a chain (a filter or a handler), the script must call the expression next.handle(context, request). If the script does not call next.handle(context, request), the chain flow breaks and the script has to build and return its own response by calling one of the following expressions:

return myResponse
return newResultPromise(myResponse)

Actions on the response returned from the downstream flow must be performed in the Promise’s callback methods.

For information about script properties, available global objects, and automatically imported classes, refer to Scripts. For information about creating scriptable objects in Studio, refer to Scripts in Studio and Configure scriptable throttling.

Usage

{
    "name": string,
    "type": "ScriptableFilter",
    "config": {
        "type": configuration expression<string>,
        "file": configuration expression<string>, // Use either "file"
        "source": [ string, ... ],                // or "source", but not both.
        "args": map,
        "clientHandler": Handler reference
    }
}

Properties

For information about properties for ScriptableFilter, refer to Scripts.

Examples

For an example scriptable filter that recovers policy advices from AM, see the failureHandler property of PolicyEnforcementFilter.

SessionInfoFilter

Calls the AM endpoint for session information, and makes the data available as a new context to downstream IG filters and handlers. For information, see SessionInfoContext.

WebSocket notifications for sessions

For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.

Usage

{
  "name": string,
  "type": "SessionInfoFilter",
  "config": {
    "amService": AmService reference,
    "ssoToken": runtime expression<string>
  }
}

Properties

"amService": AmService reference, required

The AmService object to use for communication with AM.

The following sessionProperties, are retrieved from AM:

When sessionProperties in AmService is configured, listed session properties with a value.
When sessionProperties in AmService is not configured, all session properties with a value.
Properties with a value that are required by IG but not specified by sessionProperties in AmService. For example, when the session cache is enabled, session properties related to the cache are automatically retrieved.

Properties with a value are returned, properties with a null value are not returned.

"ssoToken": runtime expression<string>, optional

Location of the AM SSO or CDSSO token.

This property can take the following values:

${contexts.ssoToken.value}, when the SingleSignOnFilter is used for authentication
${contexts.ssoToken.value} or ${contexts.cdsso.token}, when the CrossDomainSingleSignOnFilter is used for authentication
${request.headers['mySsoToken'][0]}, where the SSO or CDSSO token is the first value of the mySsoToken header in the request.

Default: ${request.cookies['AmService-ssoTokenHeader'][0].value}, where AmService-ssoTokenHeader is the name of the header or cookie where the AmService expects to find SSO or CDSSO tokens.

SetCookieUpdateFilter

Updates the attribute values of Set-Cookie headers in a cookie. This filter facilitates the transition to the SameSite and secure cookie settings required by newer browsers. Use SetCookieUpdateFilter at the beginning of a chain to guarantee security along the chain.

Set-Cookie headers must conform to grammar in RFC 6265: Set-Cookie.

Usage

{
  "name": string,
  "type": "SetCookieUpdateFilter",
  "config": {
   "cookies": {
     "cookie-name": {
       "attribute-name": "attribute-value",
       ...
     }
     ...
   }
 }
}

Properties

"cookies": map, required

Configuration that matches case-sensitive cookie names to response cookies, and specifies how matching cookies attribute values should be updated. Each cookie begins with a name-value pair, where the value is one or more attribute-value pairs.

cookie-name: pattern, required

The name of a cookie contained in the Set-Cookie header, as a pattern.

To change the attribute value on all existing cookies, specify .*.

If a cookie is named more than once, either explicitly or by the wildcard (*), the rules are applied to the cookie in the order they appear in the map.

In the following example, the SameSite attribute of the CSRF cookie first takes the value none, and then that value is overwritten by the value LAX.

"cookies": {
  "CSRF": {
    "value": "myValue",
    "secure": ${true},
    "SameSite": "none"
  }
  ".*": {
    "SameSite": "LAX"
  }
}

attribute-name: enumeration, required

A case-insensitive enumeration of a Set-Cookie attribute name.

Attribute names include SameSite, secure, http-only, value, expires, Max-Age, path, and domain. For more information, refer to RFC 6265: Set-Cookie.

Use the now dynamic binding to dynamically set the value of a cookie attribute that represents time. For example, set the value of the attribute expires to one day after the expression is evaluated, as follows:

{
  "type": "SetCookieUpdateFilter",
    "config": {
      "cookies": {
        ".*": {
          "expires": "${now.plusDays(1).rfc1123}",
...

attribute-value: runtime expression<string, boolean, or integer>, required

The replacement value for the named attribute. The value must conform to the expected type for the attribute name:

secure: runtime expression<boolean>. Required if SameSite is none
http-only: runtime expression<boolean>.
Max-Age: runtime expression<number>.
SameSite, and all other attribute names: runtime expression<string>.

For all values except expires, specify ${previous} to reuse the existing value for the attribute. The following example adds five seconds to the Max-Age attribute:

"Max-Age": "${integer(previous+5)}",

If the named the Set-Cookie header doesn’t contain the named attribute, ${previous} returns null.

Examples

The following example updates attributes of all existing Set-Cookie headers:

{
  "name": "SetCookieUpdateFilter",
  "condition": "${find(request.uri.path, '/home')}",
  "baseURI": "http://app.example.com:8081",
  "heap": [],
  "handler": {
    "type": "Chain",
    "config": {
      "filters": [{
        "type": "SetCookieUpdateFilter",
        "config": {
          "cookies": {
            ".*": {
              "SameSite": "LAX",
              "domain": "ig.example.com",
              "Max-Age": "${session.maxAge}",
              "Secure": "${true}",
              "expires": 155...833
            }
          }
        }
      }],
      "handler": "ReverseProxyHandler"
    }
  }
}

More information

org.forgerock.openig.filter.SetCookieUpdateFilter

SingleSignOnFilter

Tests for the presence and validity of an SSO token in the cookie header of a request:

If an SSO token is present, the filter calls AM to validate the SSO token. If the SSO token is valid, the request continues along the chain. The token value and additional information are stored in the ssoToken context. For information, refer to SsoTokenContext.
If the SSO token is not present, or is empty or invalid, IG checks the goto query parameter for the presence of the redirection marker:
- If the redirection marker parameter is present (for example, _ig=true), IG fails the request because the cookie domain is incorrectly configured.
- If the redirection marker is not present, IG redirects the user agent to the AM login page or another provided login page. For information about enabling, disabling, and naming the redirection marker, refer to the redirectionMarker property on this page.

For more information about SSO, refer to Authentication.

To prevent issues with performance when accessing large resources, such as .jpg and .js files, consider using the SingleSignOnFilter with the following options:

The sessionCache, so that IG can reuse session token information without repeatedly asking AM to verify the session token.
A ConditionalFilter, so that requests to access large resources skip the SingleSignOnFilter. For an example configuration, see the example in ConditionalFilter.

When AM is using CTS-based sessions, it does not monitor idle time for client-side sessions, and so refresh requests are ignored.

When the SingleSignOnFilter is used for authentication with AM, after a time AM can view the session as idle even though the user continues to interact with IG. The user session can eventually time out.

(From AM 6.5.3.) When AM is using CTS-based sessions, use the sessionIdleRefresh property of AmService to refresh idle sessions, and prevent unwanted timeouts.

WebSocket notifications for sessions

For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.

Usage

{
  "name": string,
  "type": "SingleSignOnFilter",
    "config": {
      "amService": AmService reference,
      "authenticationService": configuration expression<string>,
      "redirectionMarker": object,
      "realm": configuration expression<string>,
      "defaultLogoutLandingPage": configuration expression<url>,
      "loginEndpoint": runtime expression<url>,
      "logoutExpression": runtime expression<boolean>,
      "logoutEndpoint": pattern //deprecated
  }
}

Properties

"amService": AmService reference, required

An AmService object to use for the following properties:

agent, the credentials of the IG agent in AM. When the agent is authenticated, the token can be used for tasks such as getting the user’s profile, making policy evaluations, and connecting to the AM notification endpoint.
realm: Realm of the IG agent in AM.
url, the URL of an AM service to use for session token validation and authentication when loginEndpoint is not specified.
ssoTokenHeader, the name of the cookie that contains the session token created by AM.
amHandler, the handler to use when communicating with AM to validate the token in the incoming request.
sessionCache, the configuration of a cache for session information from AM.
version: The version of the AM server.

The AM version is derived as follows, in order of precedence:
- Discovered value: AmService discovers the AM version. If version is configured with a different value, AmService ignores the value of version and issues a warning.
- Value in version: AmService cannot discover the AM version, and version is configured.
- Default value of AM 6: AmService cannot discover the AM version, and version is not configured.

redirectionMarker: object, optional

"redirectionMarker": {
   "enabled": configuration expression<boolean>,
   "name": configuration expression<string>
}

enabled: configuration expression<boolean>, optional: When true, use a redirection marker to limit the number of authentication redirects.

When there is no SSO session due to, for example, SSO cookie name misconfiguration, an authentication request fails and is redirected back to IG. The scenario can result in infinite authentication redirects.

Consider enabling the redirection marker during development, then disabling it to prevent it being captured in bookmarks.

Default: true
name: configuration expression<string>, optional: The name of the redirection marker query parameter to use when enabled is true.

Default: _ig

"authenticationService": configuration expression<string>,optional

The name of an AM authentication tree or authentication chain to use for authentication.

Use only authentication trees with ForgeRock Identity Cloud. Authentication modules and chains are not supported.

Default: AM’s default authentication tree.

For more information about authentication trees and chains, refer to Authentication nodes and trees and Authentication modules and chains in AM’s Authentication and SSO guide.

"realm": configuration expression<string>, optional

The AM realm where the user is authenticated.

Default: The realm declared for amService.

"defaultLogoutLandingPage": configuration expression<url>, optional

The URL to which a request is redirected if logoutExpression is evaluated as true.

If this property is not an absolute URL, the request is redirected to the IG domain name.

This parameter is effective only when logoutExpression is specified.

Default: None, processing continues.

"loginEndpoint": runtime expression<url>, optional

The URL of a service instance for the following tasks:

Manage authentication and the location to which the request is redirected after authentication.
Process policy advices after an AM policy decision denies a request with supported advices. The PolicyEnforcementFilter redirects the request to this URL, with information about how to meet the conditions in the advices.

For examples of different advice types, and the conditions that cause AM to return advices, see AM’s Authorization guide. For information about supported advice types in IG, see Using Advices From Policy Decisions.

Default: The value of url in amService

Authentication can be performed in the following ways:

Directly through AM, with optional authentication parameters in the query string, such as service, module, and realm. For a list of authentication parameters that you can include in the query string, see Authenticating (browser) in AM’s Authentication and SSO guide.

The value must include a redirect with a goto parameter.

The following example uses AM as the authentication service, and includes the service authentication parameter:
```
"loginEndpoint": "https://am.example.com/openam?service=TwoFactor&goto=${urlEncodeQueryParameterNameOrValue(contexts.router.originalUri)}"
```
Through the URL of another application, with optional authentication parameters in the query string, such as service, module, and realm. The application must create a session with an AM instance to set an SSO token and return the request to the redirect location.

The value can optionally include a redirect with a goto parameter or different parameter name.

The following example uses an authentication service that is not AM, and includes a redirect parameter:
```
"loginEndpoint": "https://authservice.example.com/auth?redirect=${urlEncodeQueryParameterNameOrValue(contexts.router.originalUri)}"
```
When using this option, review the cookie domains to make sure cookies set by the authentication server are properly conveyed to the IG instance.

"logoutExpression": runtime expression<boolean>, optional

A flag to indicate that a logout condition is met. The condition is based on the request:

true: The AM session token for the end user is revoked. If a defaultLogoutLandingPage is specified, the request is redirected to that page.
false: The request continues to be processed.

The following example expressions can be used to trigger revocation of the end user token:
The request URI contains /logout:
```
${find(request.uri, '/logout')}
```
The request path starts with /logout:
```
${find(request.uri.path, '^/logout')}
```
The request query includes the logOff=true query parameter:
```
${find(request.uri.query, 'logOff=true')}
```

Default: ${false}

"logoutEndpoint": pattern, optional

The use of this property is deprecated; use logoutExpression instead. For more information, refer to the Deprecated section of the Release Notes.

A string denoting a regular expression pattern for a URL. When a request matches the pattern, IG performs the logout process and the AM authentication token for the end user is revoked.

If a defaultLogoutLandingPage is specified, the request is redirected to that page. Otherwise, the request continues to be processed.

Default: Logout is not managed by this filter.

SqlAttributesFilter

Executes a SQL query through a prepared statement and exposes its first result. Parameters in the prepared statement are derived from expressions. The query result is exposed in an object whose location is specified by the target expression. If the query yields no result, then the resulting object is empty.

The execution of the query is performed lazily; it does not occur until the first attempt to access a value in the target. This defers the overhead of connection pool, network and database query processing until a value is first required. This also means that the parameters expressions is not evaluated until the object is first accessed.

Usage

{
  "name": string,
  "type": "SqlAttributesFilter",
   "config": {
     "dataSource": JdbcDataSource reference,
     "preparedStatement": configuration expression<string>,
     "parameters": [ runtime expression<string>, ... ],
     "target": lvalue-expression
   }
}

Properties

"dataSource": JdbcDataSource reference, required

dataSource as a JNDI lookup name is deprecated; use dataSource as a JdbcDataSource configuration object instead. For more information, refer to the Deprecated section of the Release Notes.

The JdbcDataSource to use for connections. Configure JdbcDataSource as described in JdbcDataSource.

"preparedStatement": configuration expression<string>, required

The parameterized SQL query to execute, with ? parameter placeholders.

"parameters": array of runtime expressions<strings>, optional

The parameters to evaluate and include in the execution of the prepared statement.

See also Expressions.

"target": <lvalue-expression>, required

Expression that yields the target object that will contain the query results.

See also Expressions.

Example

StaticRequestFilter

Creates a new request, replacing any existing request. The request can include an entity specified in the entity parameter. Alternatively, the request can include a form, specified in the form parameter, which is included in an entity encoded in application/x-www-form-urlencoded format if request method is POST, or otherwise as (additional) query parameters in the URI. The form and entity parameters cannot be used together when the method is set to POST.

Usage

{
  "name": string,
  "type": "StaticRequestFilter",
  "config": {
    "method": configuration expression<string>,
    "uri": runtime expression<url>,
    "version": configuration expression<string>,
    "headers": {
      configuration expression<string>: [ runtime expression<string>, ... ], ...
    },
    "form": {
      configuration expression<string>: [ runtime expression<string>, ... ], ...
    },
    "entity": runtime expression<string>
  }
}

Properties

"method": configuration expression<string>, required

The HTTP method to be performed on the resource; for example, GET.

"uri": runtime expression<url>, required

The fully-qualified URI of the resource being accessed; for example, http://www.example.com/resource.txt.

"version": configuration expression<string>, optional

Protocol version.

Default: "HTTP/1.1"

"headers": map, optional

One or more headers to set for a request, with the format name: [ value, … ], where:

name is a configuration expression<string> that resolve to a header name. If multiple expressions resolve to the same final string, name has multiple values.
value is one or more runtime expression<strings> that resolve to header values.

In the following example, the header name is the value of the system variable defined in cookieHeaderName. The header value is stored in contexts.ssoToken.value:

"headers": {
  "${application['header1Name']}": [
    "${application['header1Value'}"
  ]
}

Default: Empty

"form": map, optional

A form to include in the request and/or application/x-www-form-urlencoded entity, as name-value pairs, where:

name is a configuration expression<string> that resolves to a form parameter name.
value is one or more runtime expression<strings> that resolve to form parameter values.

When a Request method is POST, form is mutually exclusive with entity.

Examples:

In the following example, the field parameter names and values are hardcoded in the form:
```
"form": {
  "username": [
    "demo"
  ],
  "password": [
    "password"
  ]
}
```

In the following example, the values take the first value of username and password provided in the session:

"form": {
  "username": [
    "${session.username[0]}"
  ],
  "password": [
    "${session.password[0]}"
  ]
}

In the following example, the name of the first field parameter takes the value of the expression ${application['formName']} when it is evaluated at startup. The values take the first value of username and password provided in the session:
```
"form": {
  "${application['formName']}": [
    "${session.username[0]}"
  ],
  "${application['formPassword']}": [
    "${session.password[0]}"
  ]
}
```
Default: Empty

"entity": runtime expression<string>, optional

The message entity body to include in a request.

When a Request method is POST, entity is mutually exclusive with form.

Methods are provided for accessing the entity as byte, string, or JSON content. For information, refer to Entity.

Attackers during reconnaissance can use messages to identify information about a deployment. For security, limit the amount of information in messages, and avoid using words that help identify IG.

Default: Empty

Example

In the following example, IG replaces the browser’s original HTTP GET request with an HTTP POST login request containing credentials to authenticate to the sample application. For information about how to set up and test this example, refer to the Getting started.

SwitchFilter

Verifies that a specified condition is met. If the condition is met or no condition is specified, the request is diverted to the associated handler, with no further processing by the switch filter.

Usage

{
    "name": string,
    "type": "SwitchFilter",
    "config": {
        "onRequest": [
            {
                "condition": runtime expression<boolean>,
                "handler": Handler reference
            },
            ...
        ],
        "onResponse": [
            {
                "condition": runtime expression<boolean>,
                "handler": Handler reference
            },
            ...
        ]
    }
}

Properties

"onRequest": array of objects, optional

Conditions to test (and handler to dispatch to, if true) before the request is handled.

"onResponse": array of objects, optional

Conditions to test (and handler to dispatch to, if true) after the response is handled.

"condition": runtime expression<boolean>, optional

A flag to indicate that a condition is met:

true: The request is dispatched to the handler.
false: The request is not dispatched to the handler, and the next condition in the list is tried.

When the last condition in the list returns false, the request is passed to the next filter or handler in the chain.

Default: ${true}

"handler": Handler reference, required

Dispatch to this handler if the condition yields true.

Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.

See also Handlers.

Example

This example intercepts the response if it is equal to 200 and executes the LoginRequestHandler. This filter might be used in a login flow where the request for the login page must go through to the target, but the response should be intercepted in order to send the login form to the application. This is typical for scenarios where there is a hidden value or cookie returned in the login page, which must be sent in the login form:

{
    "name": "SwitchFilter",
    "type": "SwitchFilter",
    "config": {
        "onResponse": [
            {
                "condition": "${response.status.code == 200}",
                "handler": "LoginRequestHandler"
            }
        ]
    }
}

ThrottlingFilter

Limits the rate that requests pass through a filter. The maximum number of requests that a client is allowed to make in a defined time is called the throttling rate.

When the throttling rate is reached, IG issues an HTTP status code 429 Too Many Requests and a Retry-After header, whose value is rounded up to the number of seconds to wait before trying the request again.

GET http://ig.example.com:8080/home/throttle-scriptable HTTP/1.1
. . .
HTTP/1.1 429 Too Many Requests
Retry-After: 10

Usage

{
    "name": string,
    "type": "ThrottlingFilter",
    "config": {
        "requestGroupingPolicy": runtime expression<string>,

        "rate": {                                            //or "rate", but not both.
            "numberOfRequests": configuration expression<number>,
            "duration": configuration expression<duration>
        },
        "cleaningInterval": configuration expression<duration>,
        "executor": ScheduledExecutorService reference
    }
}

Properties

"requestGroupingPolicy": runtime expression<string>, optional

An expression to identify the partition to use for the request. In many cases the partition identifies an individual client that sends requests, but it can also identify a group that sends requests. The expression can evaluate to the client IP address or user ID, or an OpenID Connect subject/issuer.

The value for this expression must not be null.

Default: Empty string; all requests share the same partition

See also Expressions.

"throttlingRatePolicy": ThrottlingPolicy reference, required if rate is not used

A reference to, or inline declaration of, a policy to apply for throttling rate. The following policies can be used:

This value for this parameter must not be null.

"rate": object, required if throttlingRatePolicy is not used

The throttling rate to apply to requests. The rate is calculated as the number of requests divided by the duration:

"numberOfRequests": configuration expression<integer>, required: The number of requests allowed through the filter in the time specified by "duration".

"duration": configuration expression<duration>, required: A time interval during which the number of requests passing through the filter is counted.

"cleaningInterval": configuration expression<duration>, optional: The time to wait before cleaning outdated partitions. The value must be more than zero but not more than one day.
"executor": ScheduledExecutorService reference, optional: An executor service to schedule the execution of tasks, such as the clean up of partitions that are no longer used.

Default: ScheduledExecutorService

See also ScheduledExecutorService.

Examples

The following route defines a throttling rate of 6 requests/10 seconds to requests. For information about how to set up and test this example, see Configure Simple Throttling.

TokenTransformationFilter

Transforms a token issued by AM to another token type.

The TokenTransformationFilter makes the result of the token transformation

available to downstream handlers in the sts context. For information, see StsContext.

The current implementation uses REST Security Token Service (STS) APIs to transform an OpenID Connect ID Token (id_token) into a SAML 2.0 assertion. The subject confirmation method is Bearer, as described in Profiles for the OASIS Security Assertion Markup Language (SAML) V2.0 .

The TokenTransformationFilter makes the result of the token transformation available to downstream handlers in the issuedToken property of the ${contexts.sts} context.

The TokenTransformationFilter configuration references a REST STS instance that must be set up in AM before the TokenTransformationFilter can be used. The REST STS instance exposes a preconfigured transformation under a specific REST endpoint. For information about setting up a REST STS instance, see the AM documentation.

Errors that occur during the token transformation cause a error response to be returned to the client and an error message to be logged for the IG administrator.

Usage

{
    "name": "string",
    "type": "TokenTransformationFilter",
    "config": {
        "amService": AmService reference,
        "idToken": runtime expression<string>,
        "instance": configuration expression<string>,
        "username": configuration expression<string>, //deprecated
        "password": configuration expression<string>  //deprecated
    }
}

Properties

"amService": AmService reference, required

The AmService heap object to use for the following properties:

agent, the credentials of the IG agent in AM, to authenticate IG as an AM REST STS client, and to communicate WebSocket notifications from AM to IG. This credentials are evaluated when the route is initialized
url, the URL of an AM service to use for session token validation and authentication. Authentication and REST STS requests are made to this service.
realm, the AM realm containing the following information:
- The AM application that can make the REST STS request and whose credentials are the username and password.
- The STS instance described by the instance field.
ssoTokenHeader, the name of the HTTP header that provides the SSO token for the REST STS client subject.
amHandler, the handler to use for authentication and STS requests to AM.

"idToken": runtime expression<string>, required

The value of the OpenID Connect ID token. The expected value is a string that is the JWT encoded id_token.

"instance": configuration expression<string>, required

An expression evaluating to the name of the REST STS instance.

This expression is evaluated when the route is initialized, so the expression cannot refer to request or contexts.

"username": string, required

The use of this property is deprecated; use the AmService property agent instead. For more information, refer to the Deprecated section of the Release Notes.

The username to authenticate IG as an AM REST STS client.

"password": expression, required

The use of this property is deprecated; use the AmService property agent instead. For more information, refer to the Deprecated section of the Release Notes.

The password to authenticate IG as an AM REST STS client.

Example

The following example shows a configuration for a TokenTransformationFilter:

{
  "type": "TokenTransformationFilter",
  "config": {
    "amService": "MyAmService",
    "idToken": "${attributes.openid.id_token}",
    "instance": "openig"
  }
}

For an example of how to set up and test the TokenTransformationFilter, see Transform OpenID Connect ID tokens into SAML assertions.

TransactionIdOutboundFilter

Inserts the ID of a transaction into the header of a request.

The default TransactionIdOutboundFilter is created by IG, and used in ForgeRockClientHandler, as follows:

{
     "name": "ForgeRockClientHandler",
     "type": "ForgeRockClientHandler",
     "config": {
         "filters": [ "TransactionIdOutboundFilter" ],
         "handler": "ClientHandler"
     }
}

UmaFilter

This filter acts as a policy enforcement point, protecting access as a User-Managed Access (UMA) resource server. Specifically, this filter ensures that a request for protected resources includes a valid requesting party token with appropriate scopes before allowing the response to flow back to the requesting party.

Usage

{
    "name": string,
    "type": "UmaFilter",
    "config": {
        "protectionApiHandler": Handler reference,
        "umaService": UmaService reference,
        "realm": configuration expression<string>
    }
}

Properties

"protectionApiHandler": Handler reference, required: The handler to use when interacting with the UMA authorization server for token introspection and permission requests, such as a ClientHandler capable of making an HTTPS connection to the server.

For information, see Handlers.
"umaService": UmaService reference, required: The UmaService to use when protecting resources.

For information, see UmaService.
"realm": configuration expression<string>, optional: The UMA realm set in the response to a request for a protected resource that does not include a requesting party token enabling access to the resource.

Default: uma

UriPathRewriteFilter

Rewrite a URL path, using a bidirectional mapping:

In the request flow, fromPath is mapped to toPath.
In the response flow, toPath is mapped to fromPath.

IG overwrites a response header only when all of the following conditions are true:

The response includes a header such as Location or Content-Location
The URI of the response header matches the mapping
The value of response header is a relative path or its scheme://host:port value matches the base URI.

Usage

{
  "name": string,
  "type": "UriPathRewriteFilter",
  "config": {
    "mappings": object,
    "failureHandler": Handler reference
  }
}

Properties

"mappings": object, required

One or more bidirectional mappings between URL paths. For example mappings, request scenarios, and an example route, refer to Examples.

{
  "mappings": {
    "/fromPath1": "/toPath1",
    "/fromPath2": "/toPath2",
    ...
  }
}

Paths are given by a configuration expression<string>. Consider the following points when you define paths:

The incoming URL must start with the mapping path.
When more than one mapping applies to a URL, the most specific mapping is used.
Duplicate fromPath values are removed without warning.
Trailing slashes / are removed from path values.
If the response includes a Location or Content-Location header with a toPath in its URL, the response is rewritten with fromPath.

"failureHandler": handler reference, optional

Failure handler to be invoked if an invalid URL is produced when the request path is mapped, or when the response Location or Content-Location header URI path is reverse-mapped.

Provide an inline handler declaration, or the name of a handler object defined in the heap. See also Handlers.

Default: HTTP 500

Examples

Example route

The example route changes a request URL as follows:

The baseURI overrides the scheme, host, and port of a request URL.
The UriPathRewriteFilter remaps the path of a request URL.

Requests to http://ig.example.com:8080/mylogin are mapped to http://app.example.com:8081/login.

Requests to http://ig.example.com:8080/welcome are mapped to http://app.example.com:8081/home.

Requests to http://ig.example.com:8080/other are mapped to http://app.example.com:8081/not-found, and result in an HTTP 404.

Requests to http://ig.example.com:8080/badurl are mapped to the invalid URL http://app.example.com:8081[, and invoke the failure handler.

UserProfileFilter

Queries AM to retrieve the profile attributes of an user identified by their username.

Only profile attributes that are enabled in AM can be returned by the query. The roles field is not returned.

The data is made available to downstream IG filters and handlers, in the context UserProfileContext.

Usage

{
  "name": string,
  "type": "UserProfileFilter",
  "config": {
    "username": runtime expression<string>,
    "userProfileService": UserProfileService reference
  }
}

Properties

"username": runtime expression<string>, required

The username of an AM subject. This filter retrieves profile attributes for the subject.

"userProfileService": UserProfileService reference, required

The service to retrieve profile attributes from AM, for the subject identified by username.

"userProfileService": {
  "type": "UserProfileService",
  "config": {
    "amService": AmService reference,
    "cache": object,
    "profileAttributes": [ configuration expression<string>, ... ],
    "realm": configuration expression<string>
  }
}

"amService": AmService reference, required

The AmService heap object to use for the following properties:

agent, the credentials of the IG agent in AM. When the agent is authenticated, the token can be used for tasks such as getting the user’s profile, making policy evaluations, and connecting to the AM notification endpoint.
- url: URL of the AM server where the user is authenticated.
- amHandler: Handler to use when communicating with AM to fetch the requested user’s profile.
realm: Realm of the IG agent in AM.
version: The version of the AM server.

The AM version is derived as follows, in order of precedence:
- Discovered value: AmService discovers the AM version. If version is configured with a different value, AmService ignores the value of version and issues a warning.
- Value in version: AmService cannot discover the AM version, and version is configured.
- Default value of AM 6: AmService cannot discover the AM version, and version is not configured.

"cache": object, optional

Caching of AM user profiles, based on Caffeine. For more information, see the GitHub entry, Caffeine.

When caching is enabled, IG can reuse cached profile attributes without repeatedly querying AM. When caching is disabled, IG must query AM for each request, to retrieve the required user profile attributes.

Default: No cache.

"cache": {
    "enabled": configuration expression<boolean>,
    "executor": Executor reference,
    "maximumSize": configuration expression<number>,
    "maximumTimeToCache": configuration expression<duration>,
}

enabled: configuration expression<boolean>,optional: Enable or disable caching of user profiles. When false, the cache is disabled but the cache configuration is maintained.

Default: true when cache is configured
executor: Executor reference, optional: An executor service to schedule the execution of tasks, such as the eviction of entries in the cache.

Default: ForkJoinPool.commonPool()
"maximumSize": configuration expression<number>, optional: The maximum number of entries the cache can contain.

Default: Unlimited/unbound
maximumTimeToCache: configuration expression<duration>, required: The maximum duration for which to cache user profiles.

The duration cannot be zero.

profileAttributes: array of configuration expression<strings>, optional

List of one or more fields to return and store in UserProfileContext.

Field names are defined by the underlying repository in AM. When AM is installed with the default configuration, the repository is ForgeRock Directory Services.

The following convenience accessors are provided for commonly used fields:

cn: Retrieved through ${contexts.userProfile.commonName}
dn: Retrieved through ${contexts.userProfile.distinguishedName}
realm: Retrieved through ${contexts.userProfile.realm}
username: Retrieved through ${contexts.userProfile.username}

All other available fields can be retrieved through ${contexts.userProfile.rawInfo} and ${contexts.userProfile.asJsonValue()}.

When profileAttributes is configured, the specified fields and the following fields are returned: username, _id, and _rev.

Default: All available fields are returned.

"realm": configuration expression<string>, optional

The AM realm where the subject is authenticated.

Default: The realm declared for amService.
