mode: operating mode, optional

Set the IG mode to development or production. The value is not case-sensitive.

• Development mode (mutable mode)

  Use development mode to evaluate or demo IG, or to develop configurations on a single instance. This mode is not suitable for production.

  In development mode, by default all endpoints are open and accessible. You can create, edit, and deploy routes through IG Studio, and manage routes through Common REST, without authentication or authorization.

  To protect specific endpoints in development mode, configure an ApiProtectionFilter in admin.json and add it to the IG configuration.

• Production mode (immutable mode)

  After you have developed your configuration, switch to production mode to test the configuration, to run the software in pre-production or production, or to run multiple instances of the software with the same configuration.

  In production mode, the /routes endpoint is not exposed or accessible. Studio is effectively disabled, and you cannot manage, list, or even read routes through Common REST.

  By default, other endpoints, such as /share and api/info are exposed to the loopback address only. To change the default protection for specific endpoints, configure an ApiProtectionFilter in admin.json and add it to the IG configuration.

If mode is not set, the IG mode can be set by the configuration token ig.run.mode. For more information, see Configuration Tokens(5).

Default: production

"heap": array of configuration objects, optional

The heap object configuration, described in Heap Objects(5).

You can omit an empty array.

"prefix": configuration expression<string>, optional

The base of the route for administration requests. This route and its subroutes are reserved for administration endpoints.

Default: openig

"properties": JSON object, optional

Configuration parameters declared as property variables for use in the configuration. See also Properties(5).

Default: none

"secrets": configuration object, optional

An object that configures an inline array of one or more secret stores, as defined in Secrets.

{
  "secrets": {
    "stores": [ inline secret store declaration, ... ]
  }
}

"temporaryStorage": TemporaryStorage reference, optional

Cache content during processing based on this TemporaryStorage configuration.

Define the TemporaryStorage in one of the following ways:

• An inline TemporaryStorage configuration object.

• The name of a TemporaryStorage object defined in the heap.

• A configuration expression that evaluates to the name of a TemporaryStorage object defined in the heap.

Default: use the heap object named TemporaryStorage.

See also reference and TemporaryStorage(5).

"preserveOriginalQueryString": configuration expression<boolean>, optional

Process query strings in URLs, by applying or not applying a decode/encode process to the whole query string.

The following characters are disallowed in query string URL components: ", {, }, <, >, (space), and |. For more information about which query strings characters require encoding, see Uniform Resource Identifier (URI): Generic Syntax.

• true: Preserve query strings as they are presented.

  Select this option if the query string must not change during processing, for example, in signature verification.

  If a query string contains a disallowed character, the request produces a 400 Bad Request.

• false: Tolerate disallowed characters in query string URL components by applying a decode/encode process to the whole query string.

  Select this option when a user agent or client produces query searches with disallowed characters. IG transparently encodes the disallowed characters before forwarding requests to the protected application.

  Characters in query strings are transformed as follows:

  • Allowed characters are not changed.

    For example, sep=a is not changed.

  • Percent-encoded values are re-encoded when the decoded value is an allowed character.

    For example, sep=%27 is changed to sep=', because ' is an allowed character.

  • Percent-encoded values are not changed when the decoded value is a disallowed character.

    For example, sep=%22 is not changed, because " is a disallowed character.

  • Disallowed characters are encoded.

    For example, sep=", is changed to sep=%22, because " is a disallowed character.

Default: false

"handler": Handler reference, required

Dispatch all requests to this handler.

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

See also Handlers.

"heap": array of configuration objects, optional

The heap object configuration, described in Heap Objects(5).

You can omit an empty array. If you only have one object in the heap, you can inline it as the handler value.

"properties": JSON object, optional

Configuration parameters declared as property variables for use in the configuration. See also Properties(5).

Default: none

"secrets": configuration object, optional

An object that configures an inline array of one or more secret stores, as defined in Secrets.

{
  "secrets": {
    "stores": [ inline secret store declaration, ... ]
  }
}

"temporaryStorage": TemporaryStorage reference, optional

Cache content during processing based on this TemporaryStorage configuration.

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

Default: use the heap object named TemporaryStorage. Otherwise use an internally-created TemporaryStorage object that is named TemporaryStorage and that uses default settings for a TemporaryStorage object.

See also TemporaryStorage(5).

"name": string, required except for inline objects

The unique name to give the heap object in the heap. This name is used to resolve the heap object, for example, when another heap object names a heap object dependency.

"type": string, required

The class name of the object to be created. To determine the type name, see the object's documentation in this reference.

"config": object, required

The configuration that is specific to the heap object being created.

If all the fields are optional and the configuration uses only default settings, you can omit the config field instead of including an empty config object as the field value.

IG creates the following objects when a filter with the name of the object is declared in admin.json:

"ApiProtectionFilter"

The default filter used to protect administrative APIs on reserved routes. Reserved routes are described in "Reserved Routes".

To override this filter, declare a different filter with the same name in admin.json. For more information, see AdminHttpApplication(5).

Default: a filter that allows access only from the loopback address.

"MetricsProtectionFilter"

A filter used to protect the monitoring endpoints.

By default, the Prometheus Scrape Endpoint and Common REST Monitoring Endpoint are open and accessible. No special credentials or privileges are required to access the monitoring endpoints.

To protect these monitoring endpoints, add an admin.json file to your configuration, with a filter declared in the heap and named MetricsProtectionFilter.

For an example of how to manage access, see "Protecting the Monitoring Endpoints" in the Gateway Guide. For more information about admin.json, see AdminHttpApplication(5).

"StudioProtectionFilter"

A filter to protect the Studio endpoint when IG is running in development mode.

When IG is running in development mode, by default the Studio endpoint is open and accessible. Use this filter to restrict access to Studio in development mode.

For an example configuration that requires users to authenticate with AM before they can access Studio, see "Restricting Access to Studio in Development Mode" in the Gateway Guide.

For information about accessing Studio, see "Configuring Routes With Studio" in the Getting Started Guide.

For information about mode, see AdminHttpApplication(5).

"TemporaryStorage"

The default object to use for managing temporary buffers.

Default: a TemporaryStorage object named "TemporaryStorage" with the default configuration is added to the top-level heap.

Routes can use this object without explicitly defining it. To override this object, create a TemporaryStorage heap object with the same name.

See also TemporaryStorage(5).

"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.

"handler": Handler reference, required

Either the name of a handler object defined in the heap, or an inline handler configuration object.

The chain dispatches to this handler after the request has traversed all of the specified filters.

See also Handlers.

"connections": number, optional

The maximum number of connections in the HTTP client connection pool.

Default: 64

"connectionTimeout": duration string, optional

Amount of time to wait to establish a connection, expressed as a duration

Default: 10 seconds

For information about supported formats for duration, see duration.

"connectionTimeToLive": duration string, optional

Amount of time before a reusable pooled connection expires.

Set this property to expire reusable pooled connections after a fixed duration. For example, to prevent the reuse of connections set this property in routes for applications where the IP address (baseURI) is not stable or can change.

Default: Unlimited

For information about supported formats for duration, see duration.

"disableReuseConnection": configuration expression<boolean>, optional

Whether to disable connection reuse.

Default: false

"stateTrackingEnabled": configuration expression<boolean>, optional

By default, the Apache HTTP Client does not allow connection reuse when a client certificate is used for authentication. However, because the client certificate is defined at the client level, it is acceptable for requests to the same target to share a client certificate.

Use in combination with disableReuseConnection:

disableReuseConnection	stateTrackingEnabled	Description
false (default)	true (default)	Do not allow connection reuse when a client certificate is used for authentication.
false (default)	false	Allow connection reuse when a client certificate is used for authentication.
true	true (default) or false	Do not allow connection reuse.

Default: true

"hostnameVerifier": configuration expression<enumeration>, optional

Way to handle hostname verification for outgoing SSL connections. Use one of the following values:

• ALLOW_ALL: Allow a certificate issued by a trusted CA for any hostname or domain to be accepted for a connection to any domain.

  Caution

  This setting allows a certificate issued for one company to be accepted as a valid certificate for another company.

  To prevent the compromise of TLS connections, use this setting in development mode only. In production, use STRICT.

• STRICT: Match the hostname either as the value of the the first CN, or any of the subject-alt names.

  A wildcard can occur in the CN, and in any of the subject-alt names. Wildcards match one domain level, so *.example.com matches www.example.com but not some.host.example.com.

Default: STRICT

"numberOfWorkers": number, optional

The number of worker threads dedicated to processing outgoing requests.

Increasing the value of this attribute can be useful in deployments where a high number of simultaneous connections remain open, waiting for protected applications to respond.

Default: One thread per CPU available to the JVM.

"proxy": Server reference, optional

A proxy server to which requests can be submitted. Use this property to relay requests to other parts of the network, for example, to relay requests from an internal network to the internet.

If both proxy and systemProxy are defined, proxy takes precedence.

uri: configuration expression<uri string>, required

URI of a server to use as a proxy for outgoing requests.

The result of the expression must be a string that represents a valid URI, but is not a real java.net.URI object.

username: string, required if the proxy requires authentication

Username to access the proxy server.

"passwordSecretId": configuration expression<string>, required if the proxy requires authentication

The reference to the password required to access the proxy server.

The secret ID must conform to the regex pattern: [a-zA-Z0-9]+(.[a-zA-Z0-9]+)*. The route's secret service attempts to resolve the secret ID.

In the following example, the ClientHandler passes outgoing requests to the proxy server, which requires authentication:

"handler": {
  "type": "ClientHandler",
  "config": {
     "proxy" : {
        "uri": "http://proxy.example.com:3128",
        "username": "proxyuser",
        "passwordSecretId": "myproxy.secret.id"
     }
  }
}

"soTimeout": duration string, optional

Socket timeout, after which stalled connections are destroyed, expressed as a duration

Tip

If SocketTimeoutException errors occur in the logs when you try to download large files, consider increasing soTimeout.

Default: 10 seconds

For information about supported formats for duration, see duration.

"systemProxy": boolean, optional

Submit outgoing requests to a system-defined proxy, set by the following system properties or their HTTPS equivalents:

• http.proxyHost, the host name of the proxy server.

• http.proxyPort, the port number of the proxy server. The default is 80.

• http.nonProxyHosts, a list of hosts that should be reached directly, bypassing the proxy.

This property can't be used with a proxy that requires a username and password. Use the property proxy instead.

If both proxy and systemProxy are defined, proxy takes precedence.

For more information, see Java Networking and Proxies.

Default: False.

"temporaryStorage": string, optional

Specifies the heap object to use for temporary buffer storage.

Default: The temporary storage object named TemporaryStorage, declared in the top-level heap.

tls: TlsOptions reference, optional

Configure options for connections to TLS-protected endpoints, based on a TlsOptions(5) configuration. Define a TlsOptions object inline or in the heap.

Default: Connections to TLS-protected endpoints are not configured.

"asyncBehavior": enumeration, optional

Specifies how the HTTP client behaves for asynchronous responses. Set the value to streaming or non_streaming (not case-sensitive):

• streaming: Responses are processed as soon as all headers are received. The entity content is downloaded in a background thread.

  Streaming mode reduces latency and is mandatory for Server-Sent Events (SSE) and the support of very large files (bigger than 2 GB). If thread starvation occurs, consider increasing numberOfWorkers, the number of worker threads dedicated to processing outgoing requests.

• non_streaming: Responses are processed when the entity content is entirely available.

  Non-streaming mode does not support SSE or very large files. However, it has higher latency, and does not cause thread starvation.

Default: non_streaming

"retries": object, optional

Enable and configure retry for requests.

When a runtime error occurs while executing the request to the remote server, IG schedules a new execution of the request after the specified delay, until the allowed number of retries is reached or the execution succeeds.

"enabled": boolean, optional

Enable retries.

Default: true

"executor": ScheduledExecutorService reference, optional

The ScheduledExecutorService to use for scheduling delayed execution of the request.

Default: ScheduledExecutorService.

See also ScheduledExecutorService(5).

"count": number, optional

The maximum number of retries to perform.

After this threshold is passed and if the request is still not successful, then the ClientHandler will propagate the failure.

Default: 5 retries.

"delay": duration, optional

The delay to wait before retrying the request.

After a failure to send the request, if the number of retries is below the threshold, a new attempt is scheduled with the executor service after this delay.

Default: 10 seconds.

For information about supported formats for duration, see duration.

The following example configures the handler to retry the request only once, after a 1-minute delay:

{
  "retries": {
    "count": 1,
    "delay": "1 minute"
  }
}

The following example configures the handler to retry the request at most 20 times, every second:

{
  "retries": {
    "count": 20,
    "delay": "1 second"
  }
}

The following example configures the handler to retry the request 5 times, every 10 seconds (default values), with a dedicated executor:

{
  "retries": {
    "executor": {
      "type": "ScheduledExecutorService",
      "config": {
        "corePoolSize": 20
      }
    }
  }
}

"websocket": object, optional

Enable upgrade from HTTP or HTTPS protocol to WebSocket protocol.

For more information and an example of proxying WebSocket traffic, see "Proxying WebSocket Traffic" in the Gateway Guide

Important

When IG is running in the Jetty application container, it cannot proxy WebSocket traffic.

{
  "websocket": {
    "enabled": boolean,
    "connectionTimeout": duration string,

For information about supported formats for duration, see duration.

"soTimeout": duration string, optional

The time after which stalled connections are destroyed.

Tip

If there can be long delays between messages, consider increasing this value. Alternatively, keep the connection active by using WebSocket ping messages in your application.

Default: The value of handler's main soTimeout.

For information about supported formats for duration, see duration.

"numberOfSelectors": number, optional

The maximum number of worker threads.

In deployments with a high number of simultaneous connections, consider increasing the value of this property.

Default: 2

tls: TlsOptions reference, optional

Configure options for connections to TLS-protected endpoints, based on a TlsOptions(5) configuration. Define a TlsOptions object inline or in the heap.

Default: Use TlsOptions defined for the handler

"bindings": array of objects, required

A list of bindings of conditions and associated handlers to dispatch to.

"condition": runtime expression<boolean>, optional

If the expression evaluates true, the request is dispatched to the associated handler. If no condition is specified, the request is dispatched to the associated handler unconditionally.

Default: No condition is specified.

"handler": Handler reference, required

Dispatch to this handler if the associated condition yields true.

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

See also Handlers.

"baseURI": runtime expression<uri string>, optional

A base URI that overrides the existing request URI. Only scheme, host, and port are used in the supplied URI.

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.

In the following example, the binding condition looks up the hostname of the request. If it finds a match, the value is used for the baseURI. Otherwise, the default value is used:

{
  "properties": {
    "uris": {
      "app1.example.com": {
        "baseURI": "http://backend1:8080/"
      },
      "app2.example.com": {
        "baseURI": "http://backend2:8080/"
      },
      "default": {
        "baseURI": "http://backend3:8080/"
      }
    }
  },
  "handler": {
    "type": "DispatchHandler",
    "config": {
      "bindings": [
        {
          "condition": "${not empty uris[contexts.router.originalUri.host]}",
          "baseURI": "${uris[contexts.router.originalUri.host].baseURI}",
          "handler": "ReverseProxyHandler"
        },
        {
          "baseURI": "${uris['default'].baseURI}",
          "handler": "ReverseProxyHandler"
        }
      ]
    }
  }
}

Default: No change to the base URI

"connections": number, optional

The maximum number of connections in the HTTP client connection pool.

Default: 64

"connectionTimeout": duration string, optional

Amount of time to wait to establish a connection, expressed as a duration

Default: 10 seconds

For information about supported formats for duration, see duration.

"connectionTimeToLive": duration string, optional

Enable upgrade from HTTP protocol and HTTPS protocol to WebSocket protocol.

Default: false

"connectionTimeout": duration string, optional

The maximum time allowed to establish a WebSocket connection.

Default: The value of handler's main connectionTimeout.

For information about supported formats for duration, see duration.

"soTimeout": duration string, optional

The time after which stalled connections are destroyed.

Tip

If there can be long delays between messages, consider increasing this value. Alternatively, keep the connection active by using WebSocket ping messages in your application.

In deployments with a high number of simultaneous connections, consider increasing the value of this property.

Default: 2

tls: TlsOptions reference, optional

Configure options for connections to TLS-protected endpoints, based on a TlsOptions(5) configuration. Define a TlsOptions object inline or in the heap.

Default: Use TlsOptions defined for the handler

"handler": Handler reference, required

For this route, dispatch the request to this handler.

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

See also Handlers.

"heap": array of configuration objects, optional

Heap object configuration for objects local to this route.

Objects referenced but not defined here are inherited from the parent.

You can omit an empty array. If you only have one object in the heap, you can inline it as the handler value.

See also Heap Objects(5).

"condition": runtime expression<boolean>, optional

If the expression evaluates to true, the request is dispatched to the route. If no condition is specified, the route accepts any request.

An external request can never match a condition that uses the reserved administrative route. Therefore, routes that use these conditions are effectively ignored. For example, if /openig is the administrative route, a route with the following condition would effectively be ignored: ${matches(request.uri.path, '^/openig/my/path')}.

Default: No condition is specified.

For some example route conditions, see "Setting Route Conditions" in the Gateway Guide.

See also "Reserved Routes" and Expressions(5).

"name": string, optional

Name for the route.

The Router uses the name property to order the routes in the configuration. If the route does not have a name property, the Router uses the route ID.

The route ID is managed as follows:

• When you add a route manually to the routes folder, the route ID is the value of the _id field. If there is no _id field, the route ID is the filename of the added route.

• When you add a route through the Common REST endpoint, the route ID is the value of the mandatory _id field.

• When you add a route through Studio, you can edit the default route ID.

Caution

The filename of a route cannot be default.json, and the route's name property and route ID cannot be default.

Default: route ID

"secrets": configuration object, optional

An object that configures an inline array of one or more secret stores, as defined in Secrets.

{
  "secrets": {
    "stores": [ inline secret store declaration, ... ]
  }
}

"session": Session reference, optional

Session storage implementation used by this route, such as a JwtSession as described in JwtSession(5).

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

Default: do not change the session storage implementation for session.

"defaultHandler": Handler reference, optional

Handler to use when a request does not satisfy the condition of any route.

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

Default: If no default route is set either here or in the route configurations, IG aborts the request with an internal error.

See also Handlers.

"directory": expression, optional

Base directory from which to load configuration files for routes.

Default: default base directory for route configuration files. For details, see "Installing IG" in the Gateway Guide.

The following example changes the file system location to look for routes:

{
    "type": "Router",
    "config": {
        "directory": "/path/to/safe/routes",
    }
}

Important

If you define a new router in the default base directory, then you must set the directory property to a different directory from the default base directory in order to avoid a circular reference to the new router.

See also Expressions(5).

"scanInterval": duration string or integer, optional

Time interval at which IG scans the specified directory for changes to routes. When a route is added, removed, or changed, the router updates the IG configuration without needing to restart IG or access the route.

When an integer is used for the scanInterval, the time unit is seconds.

To load routes at startup only, and prevent changes to the configuration if the routes are changed, set the scan interval to disabled.

Default: 10 seconds

For information about supported formats for duration, see duration.

"assertionMapping": object, required

The assertionMapping defines how to transform attributes from the incoming assertion to attribute value pairs in IG.

Each entry in the assertionMapping object has the form localName: incomingName, where:

• localName is the name of the attribute set in the session

• incomingName is the name of the attribute set in the incoming assertion

The following example is an assertionMapping object:

{
    "username": "mail",
    "password": "mailPassword"
}

If the incoming assertion contains the statement:

mail = george@example.com

mailPassword = C0stanza

Then the following values are set in the session:

username = george@example.com

password = C0stanza

For this to work, edit the <Attribute name="attributeMap"> element in the SP extended metadata file, $HOME/.openig/SAML/sp-extended.xml, so that it matches the assertion mapping configured in the SAML 2.0 Identity Provider (IDP) metadata.

Because the dot character (.) serves as a query separator in expressions, do not use dot characters in the localName.

To prevent different handlers from overwriting each others' data, use unique localName settings when protecting multiple service providers.

"redirectURI": string, required

Set this to the page that the filter used to HTTP POST a login form recognizes as the login page for the protected application.

This is how IG and the Federation component work together to provide SSO. When IG detects the login page of the protected application, it redirects to the Federation component. Once the Federation handler validates the SAML exchanges with the IDP, and sets the required session attributes, it redirects back to the login page of the protected application. This allows the filter used to HTTP POST a login form to finish the job by creating a login form to post to the application based on the credentials retrieved from the session attributes.

"assertionConsumerEndpoint": string, optional

Default: fedletapplication (same as the Fedlet)

If you modify this attribute you must change the metadata to match.

"authnContext": string, optional

Name of the session field to hold the value of the authentication context. Because the dot character (.) serves as a query separator in expressions, do not use dot characters in the field name.

Use this setting when protecting multiple service providers, as the different configurations must not map their data into the same fields of session. Otherwise different handlers can overwrite each others' data.

As an example, if you set "authnContext": "myAuthnContext", then IG sets session.myAuthnContext to the authentication context specified in the assertion. When the authentication context is password over protected transport, then this results in the session containing "myAuthnContext": "urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport".

Default: map to session.authnContext

"authnContextDelimiter": string, optional

The authentication context delimiter used when there are multiple authentication contexts in the assertion.

Default: |

"logoutURI": string, optional

Set this to the URI to visit after the user is logged out of the protected application.

You only need to set this if the application uses the single logout feature of the Identity Provider.

"sessionIndexMapping": string, optional

Name of the session field to hold the value of the session index. Because the dot character (.) serves as a query separator in expressions, do not use dot characters in the field name.

Use this setting when protecting multiple service providers, as the different configurations must not map their data into the same fields of session. Otherwise different handlers can overwrite each others' data.

As an example, if you set "sessionIndexMapping": "mySessionIndex", then IG sets session.mySessionIndex to the session index specified in the assertion. This results in the session containing something like "mySessionIndex": "s24ccbbffe2bfd761c32d42e1b7a9f60ea618f9801".

Default: map to session.sessionIndex

"singleLogoutEndpoint": string, optional

Default: fedletSLORedirect (same as the Fedlet)

If you modify this attribute you must change the metadata to match.

"singleLogoutEndpointSoap": string, optional

Default: fedletSloSoap (same as the Fedlet)

If you modify this attribute you must change the metadata to match.

"SPinitiatedSLOEndpoint": string, optional

Default: SPInitiatedSLO

If you modify this attribute you must change the metadata to match.

"SPinitiatedSSOEndpoint": string, optional

Default: SPInitiatedSSO

If you modify this attribute you must change the metadata to match.

"subjectMapping": string, optional

Name of the session field to hold the value of the subject name. Because the dot character (.) serves as a query separator in expressions, do not use dot characters in the field name.

Use this setting when protecting multiple service providers, as the different configurations must not map their data into the same fields of session. Otherwise different handlers can overwrite each others' data.

As an example, if you set "subjectMapping": "mySubjectName", then IG sets session.mySubjectName to the subject name specified in the assertion. If the subject name is an opaque identifier, then this results in the session containing something like "mySubjectName": "vtOk+APj1s9Rr4yCka6V9pGUuzuL".

Default: map to session.subjectName

"bindings": array of objects, required

A list of bindings of handler and postcondition to determine that sequence continues.

See also, AmService(5).

"authCookie": object, optional

The configuration of the cookie used to store the authentication.

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

• STRICT: Send the cookie only if the request was initiated from the cookie domain.

• LAX: Send the cookie only with GET requests in a first-party context, where the URL in the address bar matches the cookie domain.

The value is not case-sensitive.

Default: Null; send the cookie whenever a request is made to the cookie domain.

"secure": configuration expression<boolean>, optional

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

Default: False

"redirectEndpoint": runtime expression<uri>, required

The URI to the endpoint for CDSSO.

This URI must also be configured in AM exactly as it is configured here. For more information about configuring policy agents in AM, see Implementing Cross-Domain Single Sign-On in the Access Management Authentication and Single Sign-On Guide..

To make sure that the redirect is routed back to this filter, where the authentication can be validated, 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": "${matches(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": "${matches(request.uri.path, '^/home/cdsso')}"

  "redirectEndpoint": "/home/cdsso"

  Note

  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 that 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": "${matches(request.uri.path, '^/home/cdsso/redirect') || matches(request.uri.path, '^/ig/cdssoRedirectUri')}"

  "redirectEndpoint": "/ig/cdssoRedirectUri"

"failureHandler": Handler reference, optional

Failure handler to be invoked should an error occur during authentication.

Should an error occur during authentication, a CdSsoFailureContext(5) 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.

Should no failure handler be configured then the default failure handler is used.

See alsoHandlers.

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.

"header": boolean, optional

The setting to treat or not 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 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(5).

"key": string, required

The key used for the lookup operation.

See also Handlers.

"cacheHeader": 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

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

A map of information taken from the request or associated contexts in IG.

If this property is a map, the structure must have the format Map<String, Object>. The JSON object structure is evaluated as an expression, as follows:

• Where the object is a string: "e": "${expression}"

• Where the object is a map that contains a value to evaluate as an expression: { "e": { "n": "${nested.expression}" } }

If this property is an expression, its evaluation must give an object of type Map<String, Object>.

See also Expressions(5).

"signature": object, optional

{
  "signature": {
    "secretId":  configuration expression<secret-id>,

The following algorithms are supported but not necessarily tested in IG:

• Algorithms described in Cryptographic Algorithms for Digital Signatures and MACs.

  For RSASSA-PSS, you must install Bouncy Castle. For information, see The Legion of the Bouncy Castle.

• From IG 6.1, Ed25519 described in CFRG Elliptic Curve Diffie-Hellman (ECDH) and Signatures.

Default: RS256

"encryption": object, optional

{
  "encryption": {
    "secretId": configuration expression<secret-id>,
    "algorithm": configuration expression<string>,
    "method": configuration expression<enumeration>
  }
}

The algorithm used to encrypt the JWT.

For information about available algorithms, see "alg" (Algorithm) Header Parameter Values for JWE.

"method": configuration expression<enumeration>, required

The method used to encrypt the JWT.

For information about available methods, see "enc" (Encryption Algorithm) Header Parameter Values for JWE.

"baseURI": runtime expression<uri string>, 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(5).

What an OAuth2ClientFilter does depends on the incoming request URI. In the following list clientEndpoint represents the value of the clientEndpoint in the filter configuration:

clientEndpoint/login/?discovery=user-input&goto=url

Using the user-input value, discover and register dynamically with the end user's OpenID Provider or with the client registration endpoint as described in RFC 7591.

Upon successful registration, redirect the end user to the provider for authentication and authorization consent before redirecting the user-agent back to the callback client endpoint.

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.

Supported with OpenAM 13 and later versions, and AM 5 and later versions.

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, see ClientRegistration(5).

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.

Ultimately if the entire process is successful, the filter saves the authorization state in the context and redirects the user-agent to the specified 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.

clientEndpoint/logout?goto=url

Remove the authorization state for the end user and redirect to the specified 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.

If no goto URL is specified in the request, the defaultLogoutGoto is used.

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 during login.

Other request URIs

Restore authorization state in the specified target location and call the next filter or handler in the chain.

"clientEndpoint": runtime expression<uri string>, required

The base URI for the filter. For example, if you set "clientEndpoint": "/openid", the service URIs for this filter on your IG server are /openid/login, /openid/logout, and /openid/callback. These endpoints are implicitly reserved. 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(5).

"failureHandler": handler reference, required

Provide 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 OAuth2ClientFilter tries to refresh the access token:

• If the token is refreshed, the OAuth2ClientFilter 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 OAuth2ClientFilter 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": [ "optional 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.

"discoveryHandler": Handler reference, optional

Invoke this HTTP client handler to communicate with the OpenID Provider for OpenID Connect Discovery.

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: IG uses the default ClientHandler.

See also Handlers, ClientHandler(5).

"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 identity provider. 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.

The route in "Example Configuration For Multiple Identity Providers" includes a login handler that allows the user to choose from two client registrations, openam and google. For an example of a login handler where no client registrations are defined, see "Preparing IG for Discovery and Dynamic Registration" in the Gateway Guide.

See also Handlers.

"registrations": Array of ClientRegistration references or inline ClientRegistration declarations, optional

List of client registrations that authenticate IG to the identity providers. 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 identity provider as described in ClientRegistration(5).

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

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 URI strings, required

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

"client_name": string, optional

Name of the client to present to the end user.

"scope": space separated 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 5.5 and later versions, or with identity providers that support RFC 7591, OAuth 2.0 Dynamic Client Registration Protocol

"scopes": array of strings, optional

Array of scope strings to request of the OpenID Provider, for example:

"scopes": [
  "openid",
  "profile",
  "email"
]

This property is available for dynamic client registration with AM 5.5 and earlier versions only.

"cacheExpiration": duration string, 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.

For information about supported formats for duration, see duration.

"executor": executor, optional

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

Default: ScheduledExecutorService

See also ScheduledExecutorService(5).

"target": 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.

• If the authorization process completes successfully, the OAuth2ClientFilter 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, see "Authenticating Automatically to the Sample Application" in the Gateway Guide.

• 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(5).

"defaultLoginGoto": runtime expression<uri string>, 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.

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.

See also Expressions(5).

"defaultLogoutGoto": runtime expression<uri string>, 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.

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.

See also Expressions(5).

"requireHttps": boolean, optional

Whether to require that original target URI for the request (originalUri in UriRouterContext(5)) uses the HTTPS scheme.

Default: true.

"requireLogin": 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(5).

"accessTokenResolver": AccessTokenResolver reference, required

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

• StatelessAccessTokenResolver(5)

• OpenAmAccessTokenResolver(5)

• ConfirmationKeyVerifierAccessTokenResolver(5)

• ScriptableAccessTokenResolver(5)

"cache": object, optional

Configuration of caching for OAuth 2.0 access_tokens. By default, access_tokens are not cached.

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.

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"
}

enabled: boolean, optional

Enable or disable caching.

Default: false

defaultTimeout: configuration expression<duration string>, 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.

Default: 1 minute

maxTimeout: configuration expression<duration string>, 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.

For information about supported formats for duration, see duration.

"executor": executor, optional

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

Default: ScheduledExecutorService

See also ScheduledExecutorService(5).

"requireHttps": boolean, optional

Whether to require that original target URI for the request (originalUri in UriRouterContext(5)) uses the HTTPS scheme.

Default: true

"realm": string, optional

Default: IG

"scopes": array of runtime expression<string> or ScriptableResourceAccess object, required

A list of one of more scopes required in an OAuth 2.0 access_token to access a protected resource.

array of runtime expression<string>, required if ScriptableResourceAccess is not used

A string, array of strings, runtime expression<string>, or array of runtime expression<string> to represent one or more scopes; mutually exclusive with ScriptableResourceAccess.

ScriptableResourceAccess, required if "array of runtime expression<string>" is not used

A script that produces a list of one or more required scopes; mutually exclusive with "array of runtime expression<string>".

The script evaluates each request dynamically and returns the scopes that request needs to access the protected resource. The script must return a Promise<Set, ResponseException> or a Set<String>.

For information about the properties of ScriptableResourceAccess, see Scripts(5). For an example of how to use this property, see the examples section on this page.

{
  "name": ScriptableResourceAccess-1,
  "type": "ScriptableResourceAccess",
  "config": {
    "type": string,
    "file": expression,                     // Use either "file"
    "source": string or array of strings,   // or "source", but not both.
    "args": object,
    "clientHandler": Handler reference
  }
}

"request": request configuration object, required

The request configuration object has the following fields:

"method": string, required

The HTTP method to be performed on the resource such as GET or POST.

"uri": string, required

The fully qualified URI of the resource to access such as http://www.example.com/login.

"entity": expression, optional

The entity body to include in the request.

This setting is mutually exclusive with the form setting when the method is set to POST.

See also Expressions(5).

"form": object, optional

A form to include in the request.

The param specifies the form parameter name. Its value is an array of expressions to evaluate as form field values.

This setting is mutually exclusive with the entity setting when the method is set to POST.

"headers": object, optional

Header fields to set in the request.

The name specifies the header name. Its value is an array of expressions to evaluate as header values.

"version": string, optional

The HTTP protocol version.

The implementation uses a StaticRequestFilter. The fields are the same as those described in StaticRequestFilter(5).

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

An expression that is true when a login page is requested, false otherwise.

For example, the following expression specifies that an HTTP GET to the path /login is a request for a login page:

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

IG evaluates the expression only for the request, not for the response.

See also Expressions(5).

"loginPageContentMarker": pattern, required unless loginPage is defined

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

For an example route that uses this property, see "Login Form With Password Replay and Cookie Filters" in the Gateway Guide.

See also Patterns(5).

"credentials": Filter reference, optional

Filter that injects credentials, making them available for replay. Consider using a FileAttributesFilter or a SqlAttributesFilter.

When this is not specified, credentials must be made available to the request by other means.

See also Filters.

"headers": array of strings, optional

The names of header fields to decrypt.

Default: Do not decrypt any headers.

"loginPageExtractions": extract configuration array, optional

Object to extract values from the login page entity.

For an example route that uses this property, see "Login Which Requires a Hidden Value From the Login Page" in the Gateway Guide.

The extract configuration array is a series of configuration objects. To extract multiple values, use multiple extract configuration objects. Each object has the following fields:

"name": string, required

Name of the field where the extracted value is put.

The names are mapped into attributes.extracted.

For example, if the name is nonce, the value can be obtained with the expression ${attributes.extracted.nonce}.

The name isLoginPage is reserved to hold a boolean that indicates whether the response entity is a login page.

"pattern": pattern, required

The regular expression pattern to find in the entity.

The pattern must contain one capturing group. (If it contains more than one, only the value matching the first group is placed into attributes.extracted.)

For example, suppose the login page entity contains a nonce required to authenticate, and the nonce in the page looks like nonce='n-0S6_WzA2Mj'. To extract n-0S6_WzA2Mj, set "pattern": " nonce='(.*)'".

See also Patterns(5).

"amService": AmService reference, required

The AmService object to use for the following properties:

• agent, the credentials of an AM Java agent that acts on behalf of IG to authenticate with AM, get the user profile, and communicate WebSocket notifications from AM to IG.

• version: The version of the AM server.

See also, AmService(5).

"pepRealm": 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 no SSO is involved (API protection), then ssoTokenSubject usually points to a header value (${request.headers.iPlanetDirectoryPro[0]}).

See also Expressions(5).

"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 OAuth2ClientFilter filter before the PEP filter, and then use ${attributes.openid.id_token} as the expression value.

See also OAuth2ClientFilter(5) and Expressions(5).

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

A representation of JWT claims for the subject.

The claim "sub" must be specified. Other claims are optional.

When this property is an expression, its evaluation must give an object of type Map<String, Object>.

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

When this property is a map, the structure must have the format Map<String, Object>. The value is evaluated as an expression.

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

For an example of using claimsSubject as a map, see "Example Policy Enforcement Using claimsSubject" on this reference page.

"application": string, optional

The AM policy set to use when requesting policy decisions.

Default: 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.

Note

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"
}

For information about supported formats for duration, see duration.

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

For information about supported formats for duration, see duration.

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.

For information about supported formats for duration, see duration.

onNotificationDisconnection: configuration expression<enumeration>, optional

The strategy to manage the cache when the WebSocket notification service is disconnected, and IG receives no notifications for AM events, such as policy changes. If the cache is not cleared it can become outdated, and IG can enforce outdated policy decisions.

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 list of strings to forward to AM with the request for a policy decision, that represent the environment (or context) of the request. Forward any HTTP header or any value that the AM policy definition can use.

AM can use the 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.

If this property is a map, the structure must have the format Map<String, List<String>>. In the following example, the PolicyEnforcementFilter forwards standard and non-standard 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}"
  ]
}

If this property is an expression, its evaluation must give an object of type Map<String, List<String>>.

"environment": "${attributes.my_environment}"

"failureHandler": handler reference, optional

Handler to treat requests when they are 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,
        "entity": "Restricted area. You do not have sufficient privileges."
      }
    }
  }
}

Provide an inline handler configuration object, or the name of a handler object that is defined 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 the 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": runtime expression<boolean>,
    "includeQueryParams": runtime expression<boolean>
  }
}

useOriginalUri: runtime expression<boolean>, optional

In policy decision requests to AM, use the original URI of the request as the resource URL.

• 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: runtime expression<boolean>, optional

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://openig.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://openig.example.com:8080/login.

  For AM policies that specify resource URLs without query parameters, use this option to reduce the amount of cached information. For information about resource URLs with query parameters, see AM's Specifying Resource Patterns with Wildcards.

Default: true

ScriptableResourceUriProvider

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

"resourceUriProvider": {
  "type": "ScriptableResourceUriProvider",
  "config": {
    "type": string,
    "file": expression,                     // Use either "file"
    "source": string or array of strings,   // or "source", but not both.
    "args": object,
    "clientHandler": Handler reference
  }
}

For information about these properties, see Scripts(5).

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()"
    ]
  }
}

"amService": AmService reference, required

The AmService heap object to use for the following properties:

• agent, the credentials of an AM Java agent that acts on behalf of IG to authenticate with AM, get the user profile, and communicate WebSocket notifications from AM to IG.

• url, the URL of an AM service to use for session token validation and authentication.

• amHandler, the handler to use when communicating with AM to validate the token in the incoming request.

• realm: Realm of the AM Java agent that acts on behalf of IG.

• version: The version of the AM server.

This filter is compatible with AM version 5 or higher.

See also, AmService(5).

"ssoToken": runtime expression<string>, optional

Location of the AM SSO token. For example, with ${request.headers['mySsoToken'].values[0]} the SSO 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 tokens.

"amService": AmService reference, required

An AmService object to use for the following properties:

• agent, the credentials of an AM Java agent that acts on behalf of IG to authenticate with AM, get the user profile, and communicate WebSocket notifications from AM to IG.

• realm: Realm of the AM Java agent that acts on behalf of IG.

• 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.

See also, AmService(5).

"realm": string, optional

The AM realm where the user is authenticated.

Default: The realm declared for amService.

"defaultLogoutLandingPage": expression<uri>, optional

The URI to which a request is redirected after the user logs out of AM.

This parameter is effective only when logoutEndpoint is specified.

Default: None. Processing continues.

"loginEndpoint": URI expression, optional

The URL of a service instance for the following tasks:

• Managing authentication and the location to which the request is redirected after authentication.

• Processing 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 Policy Decision Advice in the AM 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 Authentication Parameters in the AM Authentication and Single Sign-On 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://openam.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 that cookies set by the authentication server are properly conveyed to the IG instance.

"logoutExpression" runtime expression<boolean>, optional

An expression to define a condition for logout, based on the request. If the expression evaluates to true, 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.

The following example expressions can be used to trigger revocation of the end-user token:

• The request URI contains /logout:

  ${matches(request.uri, '/logout')}

• The request path ends in /logout:

  ${matches(request.uri.path, '^/logout')}

• The request query includes the logOff=true query parameter:

  ${matches(request.uri.query, 'logOff=true')}

Default: Logout is not managed by this filter.

"dataSource": string, required

The JNDI name of the factory for connections to the physical data source.

"preparedStatement": string, required

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

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

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

See also Expressions(5).

"target": lvalue-expression, required

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

See also Expressions(5).

"method": string, required

The HTTP method to be performed on the resource (for example, "GET").

"uri": runtime expression<string>, required

The fully-qualified URI of the resource to access (for example, "http://www.example.com/resource.txt").

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.

"version": string, optional

Protocol version. Default: "HTTP/1.1".

"headers": object, optional

Header fields to set in the request, with the format name: [ value, ... ].

The name field of headers specifies the header name. It can be defined by a configuration expression or string. If the configuration expressions for multiple name resolve to the same final string, multiple values are associated with the name.

The value field of headers is an array of runtime expressions to evaluate as header values.

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

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

"form": object, optional

A form to include in the request, with the format param: [ value, ... ].

The param field of form specifies the name of the form parameter. It can be defined by a configuration expression or string. If the configuration expressions for multiple param resolve to the same final string, multiple values are associated with the param.

The value field of form is an array of runtime expressions to evaluate as form field values.

When the method is set to POST, this setting is mutually exclusive with the entity setting.

In the following example, the names of the field parameters and the values are hardcoded in the form:

"form": {
  "username": [
    "demo"
  ],
  "password": [
    "Ch4ng31t"
  ]

In the following example, the names of the field parameters are hardcoded. 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 param take 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]}"
  ]

"entity": runtime expression<string>, optional

The entity body to include in the request.

This setting is mutually exclusive with the form setting when the method is set to POST.

See also Expressions(5).

"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

If the expression evaluates to true, the request is dispatched to the handler. If no condition is specified, the request is dispatched to the handler unconditionally.

Default: No condition is specified.

See also Expressions(5).

"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.

"amService": AmService reference, required

The AmService heap object to use for the following properties:

• agent, the credentials of an AM Java agent 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.
