Guide to developing OpenAM client applications and service providers. OpenAM provides open source Authentication, Authorization, Entitlement and Federation software.
Preface
This guide demonstrates how to handle sessions to permit single sign on and single log out in OpenAM client applications. This guide further demonstrates how to use the OpenAM APIs including both APIs for client applications, and also SPIs for authentication, policy, service management, delegation, and identity storage. Finally, this guide demonstrates how to write your own web policy agent.
1. Who Should Use this Guide
This guide is written for developers who adapt client applications to use OpenAM access management capabilities. It is also written for designers and developers extending and integrating OpenAM services for their organizations.
You do not need to be an OpenAM wizard to learn something from this guide, though a background in access management and developing web applications or developing for web and application servers can help. You can nevertheless get started with this guide, and then learn more as you go along.
2. Formatting Conventions
Most examples in the documentation are created in GNU/Linux or Mac OS X
operating environments.
If distinctions are necessary between operating environments,
examples are labeled with the operating environment name in parentheses.
To avoid repetition file system directory names are often given
only in UNIX format as in /path/to/server,
even if the text applies to C:\path\to\server as well.
Absolute path names usually begin with the placeholder
/path/to/.
This path might translate to /opt/,
C:\Program Files\, or somewhere else on your system.
Command-line, terminal sessions are formatted as follows:
$ echo $JAVA_HOME /path/to/jdk
Command output is sometimes formatted for narrower, more readable output even though formatting parameters are not shown in the command.
Program listings are formatted as follows:
class Test {
public static void main(String [] args) {
System.out.println("This is a program listing.");
}

Chapter 1. OpenAM APIs and Protocols
Although policy agents and standards support make it possible for applications to use OpenAM for access management without changing your code, some deployments require tighter integration, or direct use of supported protocols and OpenAM APIs.
OpenAM supports a range of protocols and APIs that allow you not only to define specifically how access is managed in your client applications, but also to extend OpenAM capabilities to meet even those deployment requirements not yet covered in OpenAM.
This short chapter presents an overview of the APIs and protocols that OpenAM supports.
This guide primarily covers the OpenAM client APIs and SPIs, with emphasis on the Java APIs.
1.1. OpenAM APIs
OpenAM provides client application programming interfaces for a variety of needs.
The OpenAM Java APIs provided through the OpenAM Java SDK let your Java and Java EE applications call on OpenAM for authentication, and authorization in both OpenAM and federated environments.
Detailed reference information is provided in the OpenAM Java SDK API Specification.
The C SDK also provides APIs for native applications, such as new web server policy agents. The C SDK is delivered with OpenAM for Linux, Solaris, and Windows platforms.
OpenAM exposes a RESTful API that can return JSON or XML over HTTP, allowing you to access authentication, authorization, and identity services from your web applications using REST clients in the language of your choice.
1.2. OpenAM SPIs
OpenAM provides Java based service provider interfaces to let you extend services for the requirements of your particular deployment.
Some examples of the plugins you can write follow in the list below. This guide demonstrates how to implement such plugins.
Custom OAuth 2.0 scopes plugins define how OpenAM playing the role of authorization server handles scopes, including what token information to return regarding scopes set when authorization was granted.
Custom authentication plugins let OpenAM authenticate users against a new authentication service or an authentication service specific to your deployment
Post authentication plugins perform additional processing at the end of the authentication process, but before the subject is authenticated. Post authentication plugins can for example store information about the authentication in the user's profile, or call another system for audit logging purposes.
Policy evaluation plugins implement new policy conditions, send attributes from the user profile as part of a policy response, extend the definition of the subjects to whom the policy applies, or customize how policy management is delegated.
Identity repository plugins let OpenAM employ a new or custom user data store, other than a directory server or JDBC-accessible database.
Chapter 2. Developing Client Applications
Client applications access OpenAM services for authentication, authorization, and single sign on/single log out through the use of sessions. Client applications can also be allowed to manage authorization policies.
Client application integration with OpenAM can be coupled loosely, as in the case of an application running in a web server with an OpenAM policy agent to handle interaction with OpenAM service, more directly, as in the case where the client interacts with OpenAM over protocol, or tightly, as in the case of an application using the OpenAM Java or C API to interact with OpenAM services.
This part of the guide covers client interaction with OpenAM over supported protocols and using OpenAM APIs.
Chapter 3. Using RESTful Web Services
This chapter shows how to use the OpenAM RESTful interfaces for direct integration between web client applications and OpenAM.
3.1. About the RESTful API
OpenAM offers a RESTful API for these access and identity management operations:
Authentication (login)
Identity management (creating, reading, updating, deleting identities)
To call the API, access URLs under identity/ where
OpenAM is deployed, such as
https://openam.example.com:8443/openam/identity/.
You can select the output format returned by specifying
json/ or xml/ in the URL after
identity/. For example, to return JSON, specify
https://openam.example.com:8443/openam/identity/json/.
For the examples in this chapter, OpenAM has c66Encode for cookies activated. The encoding ensures that OpenAM tokens need not be percent encoded before being submitted with a request. Thus, an example token looks like this.
token.id=AQIC5wM2LY4SfczntBbXvEAOuECbqMY3J4NW3byH6xwgkGE.*AAJTSQACMDE.*
Without c66Encode activated, the same token might look like this.
token.id=AQIC5wM2LY4SfczntBbXvEAOuECbqMY3J4NW3byH6xwgkGE=@AAJTSQACMDE=#
In the latter example, you would have to percent
encode the =, @, and
# characters in your requests.
In this chapter, long URLs are wrapped to fit the printed page.
3.2. Authentication & Logout
Simple authentication with a user name and password returns a token.
$ curl "https://openam.example.com:8443/openam/identity/authenticate? username=bjensen &password=hifalutin" token.id=AQIC5wM2LY4SfcxvdvHOXjtC_eWSs2RB54tgvgK8SuYi7aQ.*AAJTSQACMDE.*
If you must specify parameters as when authenticating to
/UI/Login, you provide a percent encoded string of the
parameters as the value of the uri parameter. The
/UI/Login parameter deals with the realm,
module, and service parameters. Setting the
client parameter sets the user's IP address as part of the
token following successful authentication. The default for the client
parameter is the IP of the machine making the REST request.
$ curl "https://openam.example.com:8443/openam/identity/authenticate? username=bjensen &password=hifalutin &uri=realm%3D%2F%26module%3DDataStore &client=192.168.1.1" token.id=AQIC5wM2LY4SfcxvdvHOXjtC_eWSs2RB54tgvgK8SuYi7aQ.*AAJTSQACMDE.*
You log out using the token to end the user session.
$ curl "https://openam.example.com:8443/openam/identity/logout? subjectid=AQIC5wM2LY4SfcxvdvHOXjtC_eWSs2RB54tgvgK8SuYi7aQ.*AAJTSQACMDE.*"
3.3. Token Validation & Attribute Retrieval
You check whether a token is valid as follows.
$ curl "https://openam.example.com:8443/openam/identity/isTokenValid? tokenid=AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.*" boolean=true
An invalid token returns boolean=false.
$ curl "https://openam.example.com:8443/openam/identity/isTokenValid? tokenid=INVALID" boolean=false
With a valid token, you can retrieve attributes about the subject. OpenAM returns a series of name, value pairs.
$ curl "https://openam.example.com:8443/openam/identity/attributes?
subjectid=AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.*"
userdetails.token.id=
AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.*
userdetails.attribute.name=uid
userdetails.attribute.value=bjensen
userdetails.attribute.name=mail
userdetails.attribute.value=bjensen@example.com
userdetails.attribute.name=sn
userdetails.attribute.value=Jensen
userdetails.attribute.name=userpassword
userdetails.attribute.value={SSHA}rhusOfYpkapDWEHcfT2Y7y83LMuC++F4Abqvig==
userdetails.attribute.name=cn
userdetails.attribute.value=Babs Jensen
userdetails.attribute.value=Barbara Jensen
userdetails.attribute.name=givenname
userdetails.attribute.value=Barbara
userdetails.attribute.name=dn
userdetails.attribute.value=uid=bjensen,ou=people,dc=example,dc=com
userdetails.attribute.name=telephonenumber
userdetails.attribute.value=+1 408 555 1862
userdetails.attribute.name=objectclass
userdetails.attribute.value=organizationalPerson
userdetails.attribute.value=person
userdetails.attribute.value=posixAccount
userdetails.attribute.value=inetOrgPerson
userdetails.attribute.value=krbprincipalaux
userdetails.attribute.value=krbTicketPolicyAux
userdetails.attribute.value=topYou can specify attributes to limit what you retrieve.
$ curl "https://openam.example.com:8443/openam/identity/attributes? subjectid=AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.* &attributenames=mail &attributenames=uid" userdetails.token.id= AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.* userdetails.attribute.name=uid userdetails.attribute.value=bjensen userdetails.attribute.name=mail userdetails.attribute.value=bjensen@example.com
When retrieving attributes, you can refresh the session thus setting
the idle time to 0, by adding the boolean parameter
refresh=true to the query string.
$ curl "https://openam.example.com:8443/openam/identity/attributes? subjectid=AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.* &attributenames=cn &refresh=true" userdetails.token.id= AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.* userdetails.attribute.name=cn userdetails.attribute.value=Babs Jensen userdetails.attribute.value=Barbara Jensen
3.4. Authorization
You can call on OpenAM to decide whether to authorize access to a protected resource based on a valid token. Of course, you must percent encode the resource URI.
$ curl "https://openam.example.com:8443/openam/identity/authorize? uri=http%3A%2F%2Fwww.example.com%3A8080%2Fexamples%2Findex.html &subjectid=AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.*" boolean=true
To indicate access denied, OpenAM returns
boolean=false.
Additionally, you can access entitlements and entitlement policy
decisions using the REST interface. In order to access the entitlements
interface, you cannot however use the authentication token as is.
Instead you must encode the token as performed in
Encoder.java, and then URL-encode the
result.
The entitlements REST interface uses the following path suffixes and query string parameters.
Path suffixes for entitlements include the following.
ws/1/entitlement/decision: request a decision pertaining to a single resourcews/1/entitlement/decisions: request decisions pertaining to multiple resourcesws/1/entitlement/entitlement: request decisions for a specified resource URL and all resources underneath
Query string parameters for entitlements include the following.
subject=encoded-token, where the encoded token is as describe above.action=get, oraction=post, which identifies the user agent action when requesting a decision.application=iPlanetAMWebAgentServiceresource=resource-url, or multipleresources=resource-urlparameters for multiple decisions.env=requestDnsName%3Dfqdn,env=requestIP%3Ddotted-quads,env=requestTime%3Dseconds-since-epoch, andenv=requestDnsName%3Dtime-zonewhere time-zone is from JavaTimeZone.getTimeZone().getID(). Theenvparameters thus express conditions.
3.5. OAuth 2.0 Authorization
OpenAM exposes the following REST endpoints for different OAuth 2.0 purposes.
Endpoints for OAuth 2.0 clients and resource servers, mostly defined in RFC 6749, The OAuth 2.0 Authorization Framework, with an additional
tokeninfoendpoint useful to resource servers.An endpoint for OAuth 2.0 token administration. This is specific to OpenAM.
An endpoint for OAuth 2.0 client administration. This is specific to OpenAM.
When accessing the APIs, browser-based REST clients can rely on OpenAM to handle the session as usual. First authenticate with OpenAM. Then perform the operations in the browser session.
Clients not running in a browser can authenticate as described in
Section 3.2, "Authentication & Logout", whereby OpenAM returns a
token.id value. Clients pass the
token.id value in a header named after the
authentication cookie, by default iplanetDirectoryPro.
3.5.1. OAuth 2.0 Client & Resource Server Endpoints
As described in the Administration Guide chapter on Managing OAuth 2.0 Authorization in the Administration Guide, OpenAM exposes REST endpoints for making calls to OpenAM acting as an authorization server.
In addition to the standard authorization and token endpoints described in RFC 6749, OpenAM also exposes a token information endpoint for resource servers to get information about access tokens so they can determine how to respond to requests for protected resources. OpenAM as authorization server exposes the following endpoints for clients and resource servers.
/oauth2/authorizeAuthorization endpoint defined in RFC 6749, used to obtain an authorization grant from the resource owner
Example:
https://openam.example.com:8443/openam/oauth2/authorize/oauth2/access_tokenToken endpoint defined in RFC 6749, used to obtain an access token from the authorization server
Example:
https://openam.example.com:8443/openam/oauth2/access_token/oauth2/tokeninfoEndpoint not defined in RFC 6749, used to validate tokens, and to retrieve information such as scopes
Given an access token, a resource server can perform an HTTP GET on
/oauth2/tokeninfo?access_token=token-idto retrieve a JSON object indicatingtoken_type,expires_in,scope, and theaccess_tokenID.Example:
https://openam.example.com:8443/openam/oauth2/tokeninfo
The /oauth2/authorize, and
/oauth2/access_token endpoints function as described
in RFC 6749.
The /oauth2/authorize endpoint is protected by the
policy created during OAuth 2.0 authorization server configuration, which
grants all authenticated users access.
The /oauth2/tokeninfo endpoint takes an HTTP GET
on /oauth2/tokeninfo?access_token=token-id, and returns information about the
token.
Resource servers — or any party having the token ID — can get token information through this endpoint without authenticating. This means any application or user can validate the token without having to be registered with OpenAM.
The following example shows OpenAM issuing an access token, and then returning token information.
$ curl
--request POST
--user "myClientID:password"
--data "grant_type=password&username=demo&password=changeit&scope=cn%20mail"
https://openam.example.com:8443/openam/oauth2/access_token
{
"expires_in": 599,
"token_type": "Bearer",
"refresh_token": "f6dcf133-f00b-4943-a8d4-ee939fc1bf29",
"access_token": "f9063e26-3a29-41ec-86de-1d0d68aa85e9"
}
$ curl https://openam.example.com:8443/openam/oauth2/tokeninfo
?access_token=f9063e26-3a29-41ec-86de-1d0d68aa85e9
{
"mail": "demo@example.com",
"scope": [
"mail",
"cn"
],
"cn": "demo",
"realm": "/",
"token_type": "Bearer",
"expires_in": 577,
"access_token": "f9063e26-3a29-41ec-86de-1d0d68aa85e9"
}The resource server making decisions about whether the token is valid
can thus use the /oauth2/tokeninfo endpoint to retrieve
expiration information about the token. Depending on the scopes
implementation, the JSON response about the token can also contain scope
information. As described in the Administration Guide,
the default scopes implementation in OpenAM considers scopes to be names of
attributes in the resource owner's user profile. Notice that the JSON
response contains the values for those attributes from the user's profile,
as in the preceding example, with scopes set to mail and
cn.
3.5.2. OAuth 2.0 Token Administration Endpoint
The OpenAM-specific OAuth 2.0 token administration endpoint lets administrators read, list, and delete OAuth 2.0 tokens. OAuth 2.0 clients can also manage their own tokens.
OpenAM exposes the token administration endpoint at
/frrest/oauth2/token, such as
https://openam.example.com:8443/openam/frrest/oauth2/token.
Note
This endpoint location is likely to change in the future.
To get a token, perform an HTTP GET on
/frrest/oauth2/token/token-id,
as in the following example.
$ curl "https://openam.example.com:8443/openam/identity/authenticate?
username=amadmin&password=password"
token.id=AQIC5wM2LY4Sfcxs...EwNDU2NjE0*
$ curl
--request POST
--user "myClientID:password"
--data "grant_type=password&username=demo&password=changeit&scope=cn%20mail"
https://openam.example.com:8443/openam/oauth2/access_token
{
"expires_in": 599,
"token_type": "Bearer",
"refresh_token": "f838e7d4-7e84-4743-af7c-9a9c42c2969e",
"access_token": "9c6a48fc-44b1-4a0c-b4f0-672fba468b0f"
}
$ curl
--header "iplanetDirectoryPro: AQIC5wM2LY4Sfcxs...EwNDU2NjE0*"
https://openam.example.com:8443/openam/frrest/oauth2/token/9c6a48fc...fba468b0f
{
"scope": [
"mail",
"cn"
],

],
"expiry_time": [
"1355741494888"
],
"client_id": [
"myClientID"
]
}To list tokens, perform an HTTP GET on
/frrest/oauth2/token/?_query_id=conditions,
where conditions is a comma-separated list of
field=value
conditions. The fields are taken from the fields
returned in the token object through this endpoint.
"expiry_time"Token expiration time in milliseconds since 00:00:00 UTC, January 1, 1970.
"type"Either
"access_token"or"refresh_token"."username"OAuth 2.0 client to whom the token was issued.
"realm"The realm for which the token was issued.
"id"Unique ID of the token.
The following example shows a search for current access tokens that
were issued to myClientID.
$ curl
--header "iplanetDirectoryPro: AQIC5wM2LY4Sfcxs...EwNDU2NjE0*"
https://openam.example.com:8443/openam/frrest/oauth2/token/?_queryID
=username%3DmyClientID%2Ctype%3Daccess_token
{
"result": [
{
"scope": [
"mail",

],
"expiry_time": [
"1355741982091"
]
}
],
"pagedResultsCookie": null,
"remainingPagedResults": -1
}To delete a token, perform an HTTP DELETE on
/frrest/oauth2/token/token-id,
as in the following example.
$ curl
--request POST
--data "grant_type=client_credentials&username=demo&password=changeit
&client_id=myClientID&client_secret=password&scope=cn%20mail"
https://openam.example.com:8443/openam/oauth2/access_token
{
"expires_in": 599,
"token_type": "Bearer",
"access_token": "867aaab2-61d7-4b78-9b80-4f9098034540"
}
$ curl
--request DELETE
--header "iplanetDirectoryPro: AQIC5wM2LY4Sfcxs...EwNDU2NjE0*"
https://openam.example.com:8443/openam/frrest/oauth2/token/867aaab2..098034540
{
"success": "true"
}3.5.3. OAuth 2.0 Client Administration Endpoint
The OAuth 2.0 administration endpoint lets OpenAM administrators and agent administrators create (that is, register) and delete OAuth 2.0 clients.
OpenAM exposes this endpoint at /frrest/oauth2/client,
such as
https://openam.example.com:8443/openam/frrest/oauth2/client.
Note
This endpoint location is likely to change in the future.
To create an OAuth 2.0 client, perform an HTTP POST to
/frrest/oauth2/client/?_action=create
with a JSON object fully specifying the client, as in the following
example.
$ curl "https://openam.example.com:8443/openam/identity/authenticate
?username=amadmin&password=password"
token.id=AQIC5wM...3MTYxOA..*
$ curl --request POST --header "iplanetDirectoryPro: AQIC5wM...3MTYxOA..*"
--header "Content-Type: application/json"
--data '{"client_id":["testClient"],
"realm":["/"]
"userpassword":["secret12"],
"com.forgerock.openam.oauth2provider.clientType":["Confidential"],
"com.forgerock.openam.oauth2provider.redirectionURIs":
["www.client.com","www.example.com"],
"com.forgerock.openam.oauth2provider.scopes":["cn","sn"],
"com.forgerock.openam.oauth2provider.defaultScopes":["cn"],
"com.forgerock.openam.oauth2provider.name":["My Test Client"],
"com.forgerock.openam.oauth2provider.description":["OAuth 2.0 Client"]
}'
http://openam.example.com:8080/openam/frrest/oauth2/client/?_action=create
{"success":"true"}When creating an OAuth 2.0 client, use the following fields in your JSON object.
"client_id"(Required) This field takes an array containing the client identifier as defined in RFC 6749.
"realm"(Required) This field takes an array containing the OpenAM realm in which to create the client as defined in RFC 6749.
"userpassword"(Required) This field takes an array containing the client secret as defined in RFC 6749.
"com.forgerock.openam.oauth2provider.clientType"(Required) This field takes an array containing the client type, either
"Confidential"or"Public"as defined in RFC 6749."com.forgerock.openam.oauth2provider.redirectionURIs"(Optional for confidential clients) This field takes an array of client redirection endpoints as defined in RFC 6749.
"com.forgerock.openam.oauth2provider.scopes"(Optional) This field takes an array of scopes as defined in RFC 6749. The default scopes implementation takes scopes to be names of attributes in the resource owner profile.
Specify localized scopes in
scope|locale|localized descriptionformat."com.forgerock.openam.oauth2provider.defaultScopes"(Optional) This field takes an array of default scopes set automatically when tokens are issued.
"com.forgerock.openam.oauth2provider.name"(Optional) This field takes an array containing the client name to display to the resource owner when the resource owner must authorize client access to protected resources.
Specify localized names in
locale|localized nameformat."com.forgerock.openam.oauth2provider.description"(Optional) This field takes an array containing the description to display to the resource owner when the resource owner must authorize client access to protected resources.
Specify localized descriptions in
locale|localized descriptionformat.
To delete an OAuth 2.0 client, perform an HTTP DELETE on
/frrest/oauth2/client/client-id,
as in the following example.
$ curl --request DELETE
--header "iplanetDirectoryPro: AQIC5wM...3MTYxOA..*"
https://openam.example.com:8443/openam/frrest/oauth2/client/testClient
{"success":"true"}3.6. Logging
You can send OpenAM messages to log, specifying the message content and the log file in which to write your message.
$ curl "https://openam.example.com:8443/openam/identity/authenticate? username=amadmin &password=password" token.id=AQIC5wM2LY4SfcwyCZkk-1JXzx6q1EzgagabHfBjMidb5jI.*AAJTSQACMDE.* $ curl "https://openam.example.com:8443/openam/identity/log? appid=AQIC5wM2LY4SfcwyCZkk-1JXzx6q1EzgagabHfBjMidb5jI.*AAJTSQACMDE.* &subjectid=AQIC5wM2LY4SfcxuxIP0VnP2lVjs7ypEM6VDx6srk56CN1Q.*AAJTSQACMDE.* &logname=rest.access &message=Hello%20World"
Logging takes a valid appid token for the subject
with access to log the message, and also a subjectid token
for the user whom the message concerns. If the tokens are valid and the
access rights correct, your message ends up in the log specified.
$ cat openam/openam/log/rest.access #Version: 1.0 #Fields: time Data LoginID ContextID IPAddr LogLevel Domain LoggedBy MessageID ModuleName NameID HostName "2011-09-14 16:38:17" /home/mark/openam/openam/log/ "cn=dsameuser,ou=DSAME Users,o=openam" aa307b2dcb721d4201 "Not Available" INFO o=openam "cn=dsameuser,ou=DSAME Users,o=openam" LOG-1 rest.access "Not Available"192.168.56.2 "2011-09-14 16:38:17" "Hello World" id=bjensen,ou=user,o=openam 8a4025a2b3af291d01 "Not Available" INFO o=openam id=amadmin,ou=user,o=openam "Not Available" rest.access "Not Available" 192.168.56.2
3.7. Identity Management
This section shows how to create, read, update, and delete identities using the RESTful APIs.
OpenAM has two REST APIs for managing identities.
Under the
/json/users, you find the newer JSON-based API.Examples in this section show authentication using the API described in Section 3.2, "Authentication & Logout". For browser-based clients, you can rely on OpenAM cookies rather than construct the header in your application.
The following sections cover this JSON-based API.
Under the
/identityendpoint, you find the backwards-compatible, legacy API.The following sections cover this backwards-compatible API.
3.7.1. Creating Identities
OpenAM lets administrators create a user profile by making
an HTTP POST of the JSON representation of the profile to
/json/users/?_action=create.
The following example shows an administrator creating a new user. The
only required fields are name and
userpassword. If no other name is provided, the entry
you make for name defaults to both the user id and the
user's last name.
$ curl "https://openam.example.com:8443/openam/identity/authenticate
?username=amadmin&password=password"
token.id=AQIC5w...2NzEz*
$ curl --request POST --header "iplanetDirectoryPro: AQIC5w...2NzEz*"
--header "Content-Type: application/json"
--data '{ "name": "bjensen", "userpassword": "secret12",
"mail": "bjensen@example.com" }'
https://openam.example.com:8443/openam/json/users/?_action=create
{
"name": "bjensen",
"realm": "/",

],
"universalid": [
"id=bjensen,ou=user,dc=openam,dc=forgerock,dc=org"
]
}Alternatively, administrators can create user profiles with specific
user IDs by doing an HTTP PUT of the JSON representation of the changes to
/json/users/user-id, as
shown in the following example.
$ curl "https://openam.example.com:8443/openam/identity/authenticate
?username=amadmin&password=password"
token.id=AQIC5w...2NzEz*
$ curl --request PUT --header "iplanetDirectoryPro: AQIC5w...2NzEz*"
--header "Content-Type: application/json"
--data '{ "userpassword": "secret12", "mail": "bjensen@example.com" }'

]
}As shown in the examples, OpenAM returns the JSON representation of the profile on successful creation. On failure, OpenAM returns a JSON representation of the error including the HTTP status code.
3.7.2. Reading Identities
OpenAM lets users and administrators read profiles by requesting an HTTP
GET on /json/users/user-id.
This allows users and administrators to verify user data, status, and directory.
If users or administrators see missing or incorrect information, they can write
down the correct information and add it using Section 3.7.3, "Updating Identities".
Users can review the data associated with their accounts and administrators
can read other user's profiles. The following example shows an administrator
accessing user data. Users can view their information by changing
username=amadmin to user-id.
$ curl "https://openam.example.com:8443/openam/identity/authenticate
?username=amadmin&password=password"
token.id=AQIC5w...2NzEz*
$ curl --header "iplanetDirectoryPro: AQIC5w...2NzEz*"
https://openam.example.com:8443/openam/json/users/demo
{
"name": "demo",
"realm": "/",
"uid": [
"demo"
],
"sn": [
"demo"
],
"userpassword": [
"{SSHA}S14oR2gusLWtiDkAS4twj63slXNNaMKpwrOWdw=="
],
"cn": [

"iplanet-am-user-service",
"top"
],
"universalid": [
"id=demo,ou=user,dc=openam,dc=forgerock,dc=org"
]
}As shown in the example, OpenAM returns the JSON representation of the profile on success. On failure, OpenAM returns a JSON representation of the error including the HTTP status code.
3.7.3. Updating Identities
OpenAM lets users update their own profiles, and lets administrators
update other users' profiles. To update an identity do an HTTP PUT of the JSON
representation of the changes to /json/users/user-id.
The following example shows how users can update their own profiles.
$ curl "https://openam.example.com:8443/openam/identity/authenticate
?username=demo&password=changeit"
token.id=AQIC5...Y3MTAx*
$ curl --request PUT --header "iplanetDirectoryPro: AQIC5...Y3MTAx*"
--header "Content-Type: application/json"
--data '{ "mail": "demo@example.com" }'
https://openam.example.com:8443/openam/json/users/demo
{
"name": "demo",
"realm": "/",
"uid": [
"demo"
],
"mail": [
"demo@example.com"
],
"sn": [
"demo"
],
"userpassword": [
"{SSHA}S14oR2gusLWtiDkAS4twj63slXNNaMKpwrOWdw=="
],
"cn": [
"demo"
],
"inetuserstatus": [
"Active"
],
"dn": [
"uid=demo,ou=people,dc=openam,dc=forgerock,dc=org"
],
"objectclass": [
"person",

"organizationalperson",
"sunFMSAML2NameIdentifier",
"inetuser",
"iplanet-am-managed-person",
"sunAMAuthAccountLockout",
"iplanet-am-user-service",
"top"
],
"universalid": [
"id=demo,ou=user,dc=openam,dc=forgerock,dc=org"
]
}As shown in the example, OpenAM returns the JSON representation of the profile on success. On failure, OpenAM returns a JSON representation of the error including the HTTP status code.
3.7.4. Deleting Identities
OpenAM lets administrators delete a user profile by making an HTTP DELETE
call to /json/users/user-id.
The following example removes a user from the top level realm. Only administrators should delete users. The user id is the only field required to delete a user.
$ curl "https://openam.example.com:8443/openam/identity/authenticate
?username=amadmin&password=password"
token.id=AQIC5w...2NzEz*
$ curl --request DELETE --header "iplanetDirectoryPro: AQIC5w...2NzEz*"
https://openam.example.com:8443/openam/json/users/bjensen
{"success":"true"}On success, OpenAM returns a JSON object indicating success. On failure, OpenAM returns a JSON representation of the error including the HTTP status code.
3.7.5. Creating Identities (Legacy API)
OpenAM lets you create user profiles, and also create web and J2EE policy agent profiles. When you create an entry, you must provide the following parameters.
- admin
Valid token for the user with permissions to add the identity
- identity_name
A unique name for the identity to create
- identity_attribute_names
LDAP attribute names for attributes to create
- identity_attribute_values_name
LDAP attribute values for the identity to create. For example,
identity_attribute_names=sn&identity_attribute_values_sn=Jensen.- identity_realm
The realm in which to create the identity
- identity_type
Either
userorAgentOnly
$ curl "https://openam.example.com:8443/openam/identity/authenticate? username=amadmin &password=password" token.id=AQIC5wM2LY4SfcxSYA8eG-vrNHb_W7nG8XkfAGyRyuaebDY.*AAJTSQACMDE.* $ curl "https://openam.example.com:8443/openam/identity/create? admin=AQIC5wM2LY4SfcxSYA8eG-vrNHb_W7nG8XkfAGyRyuaebDY.*AAJTSQACMDE.* &identity_name=testuser &identity_attribute_names=cn &identity_attribute_values_cn=Test%20User &identity_attribute_names=sn &identity_attribute_values_sn=User &identity_attribute_names=userpassword &identity_attribute_values_userpassword=secret12 &identity_realm=%2F &identity_type=user"
3.7.6. Reading & Searching for Identities (Legacy API)
Reading is similar to attribute retrieval, as described in Section 3.3, "Token Validation & Attribute Retrieval", but obtained using the token of a user with permissions to perform the search, as shown in the following example.
$ curl "https://openam.example.com:8443/openam/identity/read?

- admin
Valid token for the user with access to perform the search
- attributes_names
LDAP attribute names for attributes to search
- attributes_values_name
LDAP attribute values for the identity to search. For example,
attribute_names=sn&attribute_values_sn=Jensen.- filter
Additional LDAP filter component to limit the search results returned

3.7.7. Updating Identities (Legacy API)
You can update an identity with the same parameters used to create identities, provided the token corresponds to a user with access to update the identity.
$ curl "https://openam.example.com:8443/openam/identity/update? admin=AQIC5wM2LY4SfcxSYA8eG-vrNHb_W7nG8XkfAGyRyuaebDY.*AAJTSQACMDE.* &identity_name=testuser &identity_attribute_names=mail &identity_attribute_values_mail=testuser%40example.com &identity_realm=%2F &identity_type=user"
3.7.8. Deleting Identities (Legacy API)
You can also delete an identity.
$ curl "https://openam.example.com:8443/openam/identity/delete? admin=AQIC5wM2LY4SfcxSYA8eG-vrNHb_W7nG8XkfAGyRyuaebDY.*AAJTSQACMDE.* &identity_name=testuser &identity_realm=%2F &identity_type=user"
Chapter 4. Using the OpenAM Java SDK
Important
This samples mentioned in this chapter are not available in the current release.
This chapter introduces OpenAM Java SDK. OpenAM Java SDK is delivered
in the samples/opensso-client.zip where you unpacked
the full version of OpenAM, such as
~/Downloads/opensso/samples/opensso-client.zip. To prepare
to install the OpenAM Java SDK, first unzip
opensso-client.zip.
$ mkdir -p /path/to/openam-client ; cd /path/to/openam-client $ unzip ~/Downloads/opensso/samples/opensso-client.zip
As a result, you have two directories that include the SDK and also sample command-line and web-based client applications.
src/This directory contains the SDK and client sample commands.
classes/: compiled sampleslib/: SDK and required librariesresources/: properties configuration for the SDK and samplesscripts/: installation scripts and scripts to run the samples on UNIX, Linux, and Windows systemssources/: sample code
war/This directory contains a web application archive with client samples accessible through the browser after you install the .war in a web application container.
The command-line samples access OpenAM over HTTP or HTTPS.
Compile the samples.
$ cd sdk/ $ chmod +x scripts/*.sh $ ./scripts/compile-samples.sh
Set up the samples to connect to OpenAM.
$ mkdir /path/to/openam-client/debug $ ./scripts/setup.sh Debug directory (make sure this directory exists): /path/to/openam-client/debug Application user (e.g. URLAccessAgent) password: secret12 Protocol of the server: http Host name of the server: openam.example.com Port of the server: 8080 Server's deployment URI: openam Naming URL (hit enter to accept default value, http://openam.example.com:8080/openam/namingservice): $
This sets up the configuration file for the samples,
resources/AMConfig.properties. Read the comments in the file to see the configuration settings, many of which are similar to those used by OpenAM on the server side.Check that the login sample works.
$ ./scripts/Login.sh Realm (e.g. /): Login module name (e.g. DataStore or LDAP): DataStore Login locale (e.g. en_US or fr_FR): en_US DataStore: Obtained login context User Name:amadmin Password:password Login succeeded. Logged Out!!
The web-based samples also access OpenAM over HTTP or HTTPS.
Deploy the web application.
$ mv war/opensso-client-jdk15.war /path/to/tomcat/webapps/openam-client.war
Browse to the application you deployed to configure access to OpenAM.
Use the following hints to complete the configuration.
- Server Protocol
Protocol to access OpenAM (
httporhttps)- Server Host
Fully qualified domain name for OpenAM, such as
openam.example.com- Server Port
OpenAM port number such as 8080 or 8443
- Server Deployment URI
URI entry point to OpenAM such as
/openam- Debug directory
Where to write the debug messages for the client samples
- Application user name
An user agent configured to access OpenAM, such as
UrlAccessAgentset up when OpenAM was installed- Application user password
The user agent password
After successful configuration, click the link to return to the URL where you deployed the application to view the available sample clients.
Chapter 5. Authenticating Using OpenAM Java SDK
This chapter looks at authentication with the OpenAM Java SDK and at the
sample client, Login.java, which demonstrates
authenticating to OpenAM from a client application, provided a realm, user
name, and password.
With OpenAM, your client application performs the following steps to handle authentication.
Sets up an
AuthContext, based on the realm in which the user authenticates.Starts the login process by calling the
AuthContextlogin()method.Handling authentication callbacks to retrieve credentials from the user who is authenticating.
Your application loops through the authentication callbacks by using the
AuthContextgetRequirements()andhasMoreRequirements()methods. Each time it finishes populating a callback with the credentials retrieved, your application callssubmitRequirements()to send the credentials to OpenAM's Authentication Service.After handling all authentication callbacks, your application calls the
AuthContextgetStatus()method.On login success, OpenAM sets up an
SSOTokenthat holds information about the authentication, and also about the user's environment and session.When the user logs out, your application can end the session by calling the
AuthContextlogout()method.
The AuthContext class is provided by the
com.sun.identity.authentication package, part of the
OpenAM client API. Callback classes are provided by the
javax.security.auth.callback package, which provides
callbacks for choices, confirmations, locales, names, passwords, text input,
and text output.
See the OpenAM Java SDK API Specification for reference.
As the sample client gets the realm (called organization in the sample),
locale, and authentication module to set up the authentication context,
there is not need for a language callback to get the local afterwards. The
Login.java example does, however, show simple ways of
handling callbacks for the command-line context. The implementation of
the sample client follows.

Chapter 6. Handling Single Sign On Using OpenAM Java SDK
Important
This samples mentioned in this chapter are not available in the current release.
This chapter looks at handling session tokens with the OpenAM Java SDK
using the sample client SSOTokenSample.java.
When a user authenticates successfully, OpenAM sets up a single sign on
session for the user. The session is associated with an SSO token that holds
information about the authentication, and also about the user's environment
and session. OpenAM disposes of the session when the authentication context
logout() method is called, or when a session timeout is
reached. At that point the SSO token is no longer valid.
When your application has an AuthContext after
successful authentication, you can retrieve the SSO token from the context.
You also can get the token as shown in the sample client by passing an SSO
token ID from OpenAM to an SSOTokenManager.
If your application needs to be notified of changes, you can register
an SSOTokenListener on the token by using the token's
addSSOTokenListener() method. OpenAM then calls your
SSOTokenListener ssoTokenChanged()
method when the session times out, is disposed of, or has a property that
changes.
The sample client takes an SSO token ID to get the token from OpenAM, and then displays some information from the SSO token. The implementation of the sample client follows.

// Get the SSOTokenID associated with the token and print it.
SSOTokenID id = token.getTokenID();
String tokenId = id.toString();
System.out.println("Token ID: " + tokenId);
// Set and get properties in the token.
token.setProperty("TimeZone", "PST");
token.setProperty("County", "SantaClara");
String tZone = token.getProperty("TimeZone");
String county = token.getProperty("County");
System.out.println("Property: TimeZone: " + tZone);
System.out.println("Property: County: " + county);
}
public static void main(String[] args) {
try {
System.out.print("Enter SSOToken ID: ");
String ssoTokenID = (new BufferedReader(
new InputStreamReader(System.in))).readLine();
new SSOTokenSample(ssoTokenID.trim());
} catch (SSOException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
System.exit(0);
}
}Before you run the script that calls the sample, authenticate to OpenAM
in order to have OpenAM generate the SSO token ID. To see the SSO token ID,
you can either authenticate on the command line using the RESTful
authenticate command, or alternatively run the
SSOTokenSampleServlet web-based sample.
$ scripts/SSOTokenSample.sh Enter SSOToken ID: AQIC5wM2LY4Sfcxsdru55RwePLUIbY8xTjeHf3Xnw6hphOE.*AAJTSQACMDE.* SSOToken host name: 192.168.56.1 SSOToken Principal name: id=bjensen,ou=user,o=realm,ou=services,dc=openam,dc=forgerock,dc=org Authentication type used: DataStore IPAddress of the host: 192.168.56.1 SSO Token validation test Succeeded. Token ID: AQIC5wM2LY4Sfcxsdru55RwePLUIbY8xTjeHf3Xnw6hphOE.*AAJTSQACMDE.* Property: TimeZone: PST Property: County: SantaClara
Notice both the properties populated by OpenAM, and also the two
properties, TimeZone and County, that
are set by the sample client.
6.1. Receiving Notifications
If your application implements a listener for change notification, such
as a SessionListener to handle notification when a session
is invalidated, then you must configure the following settings in the
AMConfig.properties configuration file for your
application.
- com.iplanet.am.notification.url
Set this parameter to
http://host:port/context/notificationservice.- com.iplanet.am.sdk.caching.enabled
Set this parameter to
true.- com.iplanet.am.serverMode
Set this parameter to
false.- com.sun.identity.client.notification.url
Set this parameter to
http://host:port/context/notificationservice.- com.sun.identity.idm.cache.enabled
Set this parameter to
true.- com.sun.identity.idm.remote.notification.enabled
Set this parameter to
true.- com.sun.identity.sm.cache.enabled
Set this parameter to
true.- com.sun.identity.sm.enableDataStoreNotification
Set this parameter to
true.
The above configuration to access the notification service also applies
for other types of listeners, such as ServiceListener, and
IdEventListener implementations. See the OpenAM Java SDK API Specification for details
on the available listener interfaces.
Chapter 7. Requesting Policy Decisions Using OpenAM Java SDK
Important
This samples mentioned in this chapter are not available in the current release.
This chapter shows how to request policy decision by using OpenAM Java
SDK. The chapter focuses on the sample client,
PolicyEvaluationSample.java, which demonstrates making a
request to OpenAM for a policy decision about access to a web resource.
OpenAM centralizes policy administration, policy evaluation, and policy decision making so that your applications do not have to do so. In many deployments, OpenAM policy agents and the Open Identity gateway can handle policy enforcement independently from your application code.
If your application does need to request a policy decision from OpenAM,
then your application can retrieve a PolicyEvaluator from
a client-side PolicyEvaluatorFactory, and then call the
PolicyEvaluator getPolicyDecision()
method. For boolean decisions such as allow or deny, your application can also
call the isAllowed() method.
To make a policy decision, OpenAM needs an SSOToken,
the resource to access, the action the user wants to perform on the resource
such as HTTP GET or POST, and a
Map of environment settings you can use to specify
conditions and attributes in the session or can pass back as an empty
Map if your policy does not include conditions and
response attributes.
The PolicyEvaluationSample class takes as its
configuration the user credentials, service name, resource, and action that
you provide in a Java properties file. It then authenticates the user to get
an SSOToken using the TokenUtils.java
helper methods. At that point it has sufficient information to request a
policy decision.
The implementation of the sample client follows.
package samples.policy;

public class PolicyEvaluationSample {
public PolicyEvaluationSample() {
}
public static void main(String[] args) throws Exception {
PolicyEvaluationSample clientSample = new PolicyEvaluationSample();
clientSample.runSample(args);
System.exit(0);
}
public void runSample(String[] args) throws Exception {
if (args.length == 0 || args.length > 1) {
System.out.println("Missing argument:"

} else {
System.out.println("Using properties file:" + args[0]);

);

(String)sampleProperties.get("action.name")
);
}
}
private SSOToken getSSOToken(
String userName, String password) throws Exception {
System.out.println("Entering getSSOToken():"
+ "userName=" + userName + ","
+ "password=" + password);
SSOToken ssoToken = TokenUtils.getSessionToken("/",

System.out.println("returning from getSSOToken()");
return ssoToken;
}
private void getPolicyDecision(
SSOToken ssoToken,

String resourceName,
String actionName)
throws Exception {
System.out.println("Entering getPolicyDecision():"
+ "resourceName=" + resourceName + ","
+ "serviceName=" + serviceName + ","
+ "actionName=" + actionName);
PolicyEvaluator pe = PolicyEvaluatorFactory.getInstance().
getPolicyEvaluator(serviceName);
Map env = new HashMap();
Set attrSet = new HashSet();
Set actions = new HashSet();
actions.add(actionName);
PolicyDecision pd = pe.getPolicyDecision(ssoToken, resourceName,
actions, env);
System.out.println("policyDecision:" + pd.toXML());
System.out.println("returning from getPolicyDecision()");
}
private Properties getProperties(String file)
throws MissingResourceException {
Properties properties = new Properties();
ResourceBundle bundle = ResourceBundle.getBundle(file);
Enumeration e = bundle.getKeys();
System.out.println("sample properties:");
while (e.hasMoreElements()) {
String key = (String) e.nextElement();
String value = bundle.getString(key);
properties.put(key, value);
System.out.println(key + ":" + value);
}
return properties;
}
}Before you run the script that calls the sample, edit the properties
file, resources/policyEvaluationSample.properties, to
indicate the user credentials, resource to access, and HTTP method to
use. You can use a resource that might not exist for the purposes of this
example.
user.name=demo user.password=changeit service.name=iPlanetAMWebAgentService resource.name=http://www.example.com:80/banner.html action.name=GET
Also, set up a policy in OpenAM that corresponds to the resource in
question. You can set up the policy in OpenAM console under Access Control
> Realm Name > Policies. Concerning the
Realm Name, notice that unless you change the code,
the sample uses the top-level realm, / to authenticate the
user.
With the properties configured and policy in place, get the decision
from OpenAM using the script,
scripts/run-policy-evaluation-sample.sh.
$ scripts/run-policy-evaluation-sample.sh Using properties file:policyEvaluationSample sample properties: user.password:changeit service.name:iPlanetAMWebAgentService user.name:demo resource.name:http://www.example.com:80/banner.html action.name:GET ------------------------------------------------------------------------------: Entering getSSOToken():userName=demo,password=changeit TokenID:AQIC5wM2LY4Sfcwu-JzDtYKCaxP-DxROXYd73zLlDt3fCh4.*AAJTSQACMDE.* returning from getSSOToken() Entering getPolicyDecision(): resourceName=http://www.example.com:80/banner.html, serviceName=iPlanetAMWebAgentService, actionName=GET policyDecision:<PolicyDecision> <ResponseAttributes> </ResponseAttributes> <ActionDecision timeToLive="9223372036854775807"> <AttributeValuePair> <Attribute name="GET"/> <Value>allow</Value> </AttributeValuePair> <Advices> </Advices> </ActionDecision> </PolicyDecision> returning from getPolicyDecision()
As you see, the policy decision response is formatted here as an XML document.[1] Notice here the line showing that OpenAM has allowed access to the resource.
<Value>allow</Value>
[1] The PolicyDecision element is
defined in
openam/WEB-INF/remoteInterface.dtd
where openam is the location where the OpenAM web
application is deployed.
Chapter 8. Using Fedlets in Java Web Applications
This chapter introduces OpenAM Fedlets, and shows how to use the Fedlet as part of your Java web application.
An OpenAM Fedlet is a small web application that can do federation in your service provider application with OpenAM acting as the identity provider. The Fedlet does not require an entire OpenAM installation alongside your application, but instead can redirect to OpenAM for single sign on, and to retrieve SAML assertions.
The OpenAM administrator running the identity provider server creates
a Fedlet.zip file for your service provider application,
and then sends you the .zip.
(Optional) Before creating the Fedlet, create a Hosted Identity Provider if you have not already done so.
On the Common Tasks page of the OpenAM console, click Create Fedlet.
Note that the Circle of Trust includes your hosted identity provider, and that Identity Provider is set to your to hosted identity provider.
Name the Fedlet, and also set the Destination URL.
You can use the deployment URL, such as
http://www.example.com:8080/fedletas both the name and the destination URL.If you must map attributes to match profiles on the service provider, set up the attribute mapping.
To prepare to perform the Fedlet Attribute Query example, set
CommonName=cn,GivenName=sn, andUserStatus=inetUserStatus.Click create to generate the Fedlet.zip file, such as
$HOME/openam/myfedlets/httpwwwexamplecom8080fedlet/Fedlet.zip.Provide the Fedlet to the service provider.
Fedlet.zip includes the
fedlet.war archive corresponding to the identity
provider, and a README file.
The
fedlet.wararchive contains both the Fedlet as a demo web application, and also the files you use to include the Fedlet in your service provider application.The README file describes how to use the Fedlet.
Deploy the Fedlet in your web container.
$ unzip Fedlet.zip $ mv fedlet.war /path/to/tomcat/webapps
Browse to the Fedlet URL, and then click the links to set up the configuration directory in
$HOME/fedlet, where $HOME corresponds to the user running the web application container.In the Fedlet configuration directory, set up a JKS keystore file, keystore password file, and key password file.
For demo purposes, you can copy the test
keystore.jks,.keypass, and.storepassfrom the OpenAM identity provider.$ cd /home/user/openam/openam $ scp keystore.jks .keypass .storepass www.example.com:/home/user/fedlet/ user@www.example.com's password: keystore.jks 100% 1348 1.3KB/s 00:00 .keypass 100% 36 0.0KB/s 00:00 .storepass 100% 36 0.0KB/s 00:00
Try one or more examples from the Fedlet home page to validate Fedlet setup.
After setting up OpenAM with the default subjects, you can login on the identity provider with user name
demoand passwordchangeit.
The Fedlet includes the following files that you use when building your own service provider application based on the demo web application, including a set of JavaServer Pages (JSP) examples.
conf/Configuration files copied to
$HOME/fedletwhen you first deploy and configure the Fedlet. When deploying your application, you can move these to an alternate location passed to the Java virtual machine for the web application container at startup. For example, if you store the configuration under/export/fedlet/, then you could pass the following property to the JVM.-Dcom.sun.identity.fedlet.home=/export/fedlet/conf
You do not need to include these files in your application.
fedletAttrQuery.jsp,fedletAttrResp.jspSample SAML attribute query and response handlers. See the Fedlet README file for more information.
fedletEncode.jspUtility JSP to encode a password, such as the password used to protect a Java keystore
fedletSampleApp.jsp,index.jspDemo application. You can remove these before deployment to replace them with your application.
fedletXACMLQuery.jsp,fedletXACMLResp.jspSample SAML XACML query and response handlers. See the Fedlet README file for more information.
logout.jspUtility page to perform single log out
saml2/jsp/JSPs to initiate single sign on and single logout, and to handle error, and also a JSP for obtaining Fedlet metadata,
saml2/jsp/exportmetadata.jspWEB-INF/classes/Localized Java properties files for strings used in the Fedlet user interface
WEB-INF/lib/Fedlet libraries required by your application
WEB-INF/web.xmlFedlet web application configuration, showing how JSPs map to URLs used in the Fedlet. Add mappings for your application before deployment.
In the
web.xmlmappings, your application must be mapped to/fedletapplication, as this is the assertion consumer URL set in the Fedlet metadata.<servlet> <servlet-name>yourApp</servlet-name> <jsp-file>/fedletSampleApp.jsp</jsp-file> </servlet> <servlet-mapping> <servlet-name>yourApp</servlet-name> <url-pattern>/fedletapplication</url-pattern> </servlet-mapping>
Follow these steps for a very simple demonstration of how to customize the Fedlet.
Backup
fedletSampleApp.jsp.$ cd /path/to/tomcat/webapps/fedlet/ $ cp fedletSampleApp.jsp fedletSampleApp.jsp.orig
Edit
fedletSampleApp.jspto reduce it to a single redirection tomyapp.jsp. An implementation of the <html> element of the file follows below.<html> <head> <title>Fedlet Sample Application</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <% // BEGIN : following code is a must for Fedlet (SP) side application Map map; try { // invoke the Fedlet processing logic. this will do all the // necessary processing conforming to SAMLv2 specifications, // such as XML signature validation, Audience and Recipient // validation etc. map = SPACSUtils.processResponseForFedlet(request, response); response.sendRedirect("myapp.jsp"); } catch (SAML2Exception sme) { SAMLUtils.sendError(request, response, response.SC_INTERNAL_SERVER_ERROR, "failedToProcessSSOResponse", sme.getMessage()); return; } catch (IOException ioe) { SAMLUtils.sendError(request, response, response.SC_INTERNAL_SERVER_ERROR, "failedToProcessSSOResponse", ioe.getMessage()); return; } catch (SessionException se) { SAMLUtils.sendError(request, response, response.SC_INTERNAL_SERVER_ERROR, "failedToProcessSSOResponse", se.getMessage()); return; } catch (ServletException se) { SAMLUtils.sendError(request, response, response.SC_BAD_REQUEST, "failedToProcessSSOResponse", se.getMessage()); return; } // END : code is a must for Fedlet (SP) side application %> </body> </html>Add a
myapp.jsppage to the Fedlet, such as the following.<html> <head> <title>My Application</title> <meta http-equiv="Content-Type" content="text/html" /> </head> <body> <h1>My Application</h1> <p>After you change the <code>fedletSampleApp.jsp</code>, all it does is redirect to this home page after successful login.</p> <p>See the fedlet README file and example JSPs for hints on how to retrieve attributes from OpenAM, or to send XACML queries for policy decisions.</p> </body> </html>
Browse to the Fedlet URL, such as
http://www.example.com:8080/fedlet/, and try one of the login methods.After login you are redirected to
myapp.jsp.
8.1. Signing & Encryption
By default when you create the Java Fedlet, signing and encryption are not configured. You can however set up OpenAM and the fedlet to sign and to verify XML signatures and to encrypt and to decrypt data such as SAML assertions.
Enable signing and encryption for the Java Fedlet involves the following high level stages.
Before you create the Fedlet, configure the IDP to sign and encrypt data. See Federation > Entity Providers > IDP Name > Signing and Encryption in the OpenAM console.
For evaluation, you can use the
testcertificate delivered with OpenAM.Initially deploy and configure the Fedlet, but do not use the Fedlet until you finish.
On the Fedlet side set up a JKS keystore used for signing and encryption. For evaluation, you can use copy the
keystore.jksfile delivered with OpenAM. You can find the file under the configuration directory for OpenAM, such as$HOME/openam/openam/for a server instance with base URIopenam. The built-in keystore includes thetestcertificate.You must also set up
.storepassand.keypassfiles using thefedletEncode.jsppage, such ashttp://www.example.com:8080/fedlet/fedletEncode.jsp, to encode passwords on the Fedlet side. The passwords for the test key store and private key are bothchangeit.Configure the Fedlet to perform signing and encryption by ensuring the Fedlet has access to the key store, and by updating the SP metadata for the Fedlet.
Import the updated SP metadata into the IDP to replace the default Fedlet configuration.
Restart the Fedlet or container in which the Fedlet runs for the changes you made on the Fedlet side to take effect.
The FederationConfig.properties file specifies
the paths to the JKS keystore holding the signing or encryption keys for
the Fedlet, the keystore password file, and the private key password
file.
After setting up your keystore and password files as described above, edit the properties file in the configuration directory, such as
$HOME/fedlet/FederationConfig.properties, to point to the keystore and password files.Export the certificate to use for signing and encryption purposes.
$ keytool -export -rfc -keystore keystore.jks -alias test Enter keystore password: -----BEGIN CERTIFICATE----- MIICQDCCAakCBEeNB0swDQYJKoZIhvcNAQEEBQAwZzELMAkGA1UEBhMCVVMxEzARBgNVBAgTCkNh bGlmb3JuaWExFDASBgNVBAcTC1NhbnRhIENsYXJhMQwwCgYDVQQKEwNTdW4xEDAOBgNVBAsTB09w ZW5TU08xDTALBgNVBAMTBHRlc3QwHhcNMDgwMTE1MTkxOTM5WhcNMTgwMTEyMTkxOTM5WjBnMQsw CQYDVQQGEwJVUzETMBEGA1UECBMKQ2FsaWZvcm5pYTEUMBIGA1UEBxMLU2FudGEgQ2xhcmExDDAK BgNVBAoTA1N1bjEQMA4GA1UECxMHT3BlblNTTzENMAsGA1UEAxMEdGVzdDCBnzANBgkqhkiG9w0B AQEFAAOBjQAwgYkCgYEArSQc/U75GB2AtKhbGS5piiLkmJzqEsp64rDxbMJ+xDrye0EN/q1U5Of+ RkDsaN/igkAvV1cuXEgTL6RlafFPcUX7QxDhZBhsYF9pbwtMzi4A4su9hnxIhURebGEmxKW9qJNY Js0Vo5+IgjxuEWnjnnVgHTs1+mq5QYTA7E6ZyL8CAwEAATANBgkqhkiG9w0BAQQFAAOBgQB3Pw/U QzPKTPTYi9upbFXlrAKMwtFf2OW4yvGWWvlcwcNSZJmTJ8ARvVYOMEVNbsT4OFcfu2/PeYoAdiDA cGy/F2Zuj8XJJpuQRSE6PtQqBuDEHjjmOQJ0rV/r8mO1ZCtHRhpZ5zYRjhRC9eCbjx9VrFax0JDC /FfwWigmrW0Y0Q==

In OpenAM console delete the original SP entity configuration for the Fedlet, and then import the updated metadata for the new configuration into OpenAM on the IDP side.
Restart the Fedlet or the container in which it runs in order for the Fedlet to pick up the changes to the configuration properties and the metadata.
Chapter 9. Using Fedlets in .NET Applications
This chapter explains how to use the Fedlet in your .NET application. You must configure the OpenAM .NET Fedlet to work with the identity provider. Before creating the Fedlet, therefore, set up a Hosted Identity Provider in OpenAM.
Before you start, create the hosted identity provider, and the Circle
of Trust to which you plan to add the Fedlet. You can perform these steps
using the Create Hosted Identity Provider wizard on the Common Tasks page of
the OpenAM console. The .NET Fedlet demo requires a signing key for the
Identity Provider. For evaluation, use the test
certificate installed with OpenAM.
Follow these steps to configure and install the .NET Fedlet demo application.
Download the .NET Fedlet (
Fedlet-aspnet.zip). Unpack the contents of the .zip file into a working directory.bin\This folder contains the
Fedlet.dlllibrary, that you copy to your application'sbin\folder.conf\This folder contains the templates you edit to prepare your Fedlet configuration, including the identity provider and Fedlet (SP) metadata for federation. The completed configuration files belong in your application's
App_Data\folder.readme.txtThis file describes how to set up and configure .NET Fedlets.
SampleApp\This folder contains the demo application.
Edit the template files in the
SampleApp\App_Data\folder based on where you deploy the Fedlet demo application, and on how your identity provider is configured.Edit
fedlet.cotto setcot-nameto the name of the Circle of Trust, and to setsun-fm-trusted-providersto include the entity ID of the identity provider, and the entity ID of the Fedlet service provider.Edit
sp.xmlandsp-extended.xmlto configure the entity IDs, URLs, and Circle of Trust names to correspond to your sample application.
Export the identity provider metadata from OpenAM, and copy the resulting
idp.xmlandidp-extended.xmlmetadata to the FedletSampleApp\App_Data\folder.$ ssoadm create-metadata-templ --entityid "http://idp.example.com:8080/openam" --adminid amadmin --password-file /tmp/pwd.txt --identityprovider /idp --meta-data-file idp.xml --extended-data-file idp-extended.xml --idpscertalias test Hosted entity configuration was written to idp-extended.xml. Hosted entity descriptor was written to idp.xml.
Register the Fedlet with OpenAM as a remote service provider using the
sp.xmlandsp-extended.xmlmetadata.$ ssoadm import-entity --adminid amadmin --password-file /tmp/pwd.txt --cot fedlet-cot --meta-data-file sp.xml --extended-data-file sp-extended.xml Import file, sp.xml. Import file, sp-extended.xml.
Deploy the demo application in Internet Information Server.
Note
IIS must be installed with ASP.NET and additional application support necessary for web applications beyond static web sites. The additional support is not necessarily installed by default when you activate IIS as a Windows feature.
Try the demo application links to run Fedlet initiated single sign on using HTTP POST binding and HTTP Artifact binding.
If you are using the embedded directory as a user store, you can authenticate to OpenAM using the
demouser whose password ischangeit.
Chapter 10. Using Secure Attribute Exchange
Important
This samples mentioned in this chapter are not available in the current release.
Most deployments can rely on OpenAM to handle authentication and provide identity assertions. Not only does OpenAM support a wide variety of authentication scenarios out of the box, but OpenAM also makes it possible to add custom authentication modules. Furthermore OpenIG lets you integrate legacy systems into your access management deployment.
In a deployment where you need OpenAM to act as a SAML 2.0 gateway to a legacy application that serves as an identity provider, you can use OpenAM Secure Attribute Exchange (SAE). On the identity provider side, SAE lets OpenAM retrieve the information needed to create assertions from an external authentication service, bypassing OpenAM authentication and trusting the external service as the authoritative source of authentication. On the service provider side, SAE lets OpenAM securely provide attributes to an application that makes its own policy decision based on the attributes rather than rely on OpenAM for the policy decision.
When you use SAE on the identity provider side, an external application
acts as the authoritative source of authentication. After a user authenticates
successfully, the application lets OpenAM know to create a session by sending
a secure HTTP GET or POST to OpenAM that asserts the identity of the user.
OpenAM processes the assertion to create a session for the user. If the user
is already authenticated and comes back to access the application, the
application sends a secure HTTP POST to OpenAM to assert both the user's
identity and also any necessary attributes related to the user. OpenAM
processes the assertion to create the session for the user and populate the
attributes in the user's session. When the user logs out, the external
authentication application can initiate single logout from the identity
provider OpenAM server by sending the sun.cmd=logout
attribute to OpenAM using SAE.
On the service provider side OpenAM communicates using SAML 2.0 with OpenAM on the identity provider side. OpenAM can use SAE to transmit attributes to an application through a secure HTTP POST.
SAE relies either on shared keys and symmetric encryption, or on public and private keys and asymmetric encryption to protect attributes communicated between OpenAM and external applications.
OpenAM ships with sample JSPs that demonstrate secure attribute exchange. In order to try the sample, you must set up an OpenAM circle of trust to include an identity provider and a service provider, install the SDK sample web application on each provider and then configure the providers appropriately as described in this chapter to secure communications with the sample SAE applications on both the identity provider and service provider sides.
10.1. Installing the Samples
Set up an OpenAM server as an identity provider, and another as a
service provider, connecting the two in a circle of trust called
samplesaml2cot. Configure both the hosted providers and
also the remote providers as described in Setting Up SAML
2.0 SSO in the Administration Guide. This chapter assumes you set up the hosted
identity provider at http://idp.example.com:8080/openam
and the hosted service provider at
http://sp.example.com:8080/openam. Use Common Tasks >
Test Federation Connectivity in OpenAM console to make sure Federation is
working before you add secure attribute exchange applications that rely
on functioning SAML 2.0 communications between the providers.
Set up the sample web application as described in Installing OpenAM
Client SDK Samples in the Installation Guide, both on the identity provider side
and also on the service provider side. The SAE samples are found under
/saml2/sae where you installed the samples.
saeIDPApp.jsp is the identity provider side external
application. saeSPApp.jsp is the service provider side
external application.
10.2. Preparing to Secure SAE Communications
In order for SAE to be secure, you must both set up a trust relationship between the application on the identity provider side and the OpenAM server acting as identity provider, and also set up a trust relationship between the application on the service provider side and the OpenAM server acting as the service provider. These trust relationships can be based on a shared secret and symmetric encryption, or on public and private key pairs and asymmetric encryption. The trust relationships on either side are independent. In other words you can for example use a shared secret on the identity provider side and certificates on the service provider side if you chose.
When using symmetric encryption, you must define a shared secret
string used both for the application and the provider. The sample uses
secret12 as the shared secret. To simplify
configuration, the sample uses the same shared secret, and thus
symmetric encryption, for both trust relationships.
When using symmetric encryption, you must also use the encoded
version of your shared secret. To get the encoded version of a shared
secret string, use the encode.jsp page on the
provider, as in
http://idp.example.com:8080/openam/encode.jsp and
http://sp.example.com:8080/openam/encode.jsp. An
encoded version of secret12 looks something like
AQICEcFhDWmb6sVmMuCJuVh43306HVacDte9.
When using asymmetric encryption, you must obtain a public-private key pair for the application, and store the keys in a key store on the application side. Also store the public key from OpenAM which is acting as the provider in the application's key store. Make note of the certificate aliases for your application's private key, and for OpenAM's public key. Also note the path to the key store for your application, the key store password, and the private key password.
10.3. Securing the Identity Provider Side
This configuration uses the default sample settings with a shared
secret of secret12, without encryption of the
attributes.
Login as
amadminto the OpenAM server console where you set up the hosted identity provider (IDP).As the sample includes a
branchattribute not found in user profiles by default, under Access Control > Realm Name > Authentication > All Core Settings..., set User Profile to Ignored, and then Save your work.Under Federation > Entity Providers, click the name for the Hosted IDP in order to access the IDP configuration.
Under Assertion Processing > Attribute Mapper, add both
mail=mailandbranch=branchto the attribute map, and then Save your work.Under Advanced > SAE Configuration, make sure the IDP URL reflects an endpoint on the IDP such as
http://idp.example.com:8080/openam/idpsaehandler/metaAlias/idp, and then Save your work.Also under Advanced > SAE Configuration > Application Security Configuration, add the URL value for the kind of encryption you are using, and then Save your work.
When using the defaults, the value is something like
url=http://idp.example.com:8080/samples/saml2/sae/saeIDPApp.jsp|type=symmetric|secret=encoded-secret, where the OpenAM SDK sample web application is deployed on the IDP side with context root/samplesand the encoded-secret is something likeAQICEcFhDWmb6sVmMuCJuVh43306HVacDte9.If you use a different mechanism to secure the communications between the SAE application and the provider, read the online help in the console to see how to construct your URL value.
Under Federation > Entity Providers, click the name for the Remote SP in order to access the SP configuration on the IDP side.
Under Assertion Processing > Attribute Mapper, add both
mail=mailandbranch=branchto the attribute map, and then Save your work.Under Advanced > SAE Configuration, make sure the SP URL reflects an endpoint on the SP such as
http://sp.example.com:8080/openam/spsaehandler/metaAlias/sp, and then Save your work.Also under Advanced > SAE Configuration, add the URL to the sample SAE application as the SP Logout URL such as
http://sp.example.com:8080/samples/saml2/sae/saeSPApp.jsp, and then Save your work.
10.4. Securing the Service Provider Side
This configuration uses the default sample setting of symmetric
encryption, with a shared secret of secret12.
Login as amadmin to the OpenAM server console where
you set up the hosted service provider (SP).
As the sample includes a
branchattribute not found in user profiles by default, under Access Control > Realm Name > Authentication > All Core Settings..., set User Profile to Ignored, and then Save your work.Under Federation > Entity Providers, click the name for the Hosted SP in order to access the SP configuration.
Under Assertion Processing > Attribute Mapper, add both
mail=mailandbranch=branchto the attribute map, and then Save your work.Also under Assertion Processing > Attribute Mapper > Auto Federation, select Enabled, set the Attribute to
mail, and then Save your work.Under Advanced > SAE Configuration, make sure the SP URL reflects an endpoint on the SP such as
http://sp.example.com:8080/openam/spsaehandler/metaAlias/sp, and then Save your work.Furthermore, under Advanced > SAE Configuration, add the URL to the sample SAE application as the SP Logout URL such as
http://sp.example.com:8080/samples/saml2/sae/saeSPApp.jsp, and then Save your work.Also under Advanced > SAE Configuration > Application Security Configuration, add the URL value for the kind of encryption you are using, and then Save your work.
When using the defaults, the value is something like
url=http://sp.example.com:8080/samples/saml2/sae/saeSPApp.jsp|type=symmetric|secret=encoded-secret, where the OpenAM SDK sample web application is deployed on the IDP side with context root/samplesand the encoded-secret is something likeAQICkX24RbZboAVgr2FG1kWoqRv1zM2a6KEH.If you use a different mechanism to secure the communications between the SAE application and the provider, read the online help in the console to see how to construct your URL value.
10.5. Trying It Out
After completing the setup described above, navigate to the IDP side
SAE application, for example at
http://idp.example.com:8080/samples/saml2/sae/saeIDPApp.jsp.
Make sure you set at least the "SP App URL" and "SAE URL on IDP end" to fit your configuration. For example if you used the settings above then use the following values.
- SP App URL
http://sp.example.com:8080/samples/saml2/sae/saeSPApp.jsp- SAE URL on IDP end
http://idp.example.com:8080/openam/idpsaehandler/metaAlias/idp
Check the settings, and then click Generate URL to open the Secure Attributes Exchange IDP APP SAMPLE page.
Click the ssourl link in the page to start the
exchange.
The resulting web page shows the attributes exchanged, including the mail and branch values used. The text of that page is something like the following.
SAE SP APP SAMPLE Secure Attrs : mail testuser@foo.com sun.idpentityid http://idp.example.com:8080/openam sun.spentityid http://sp.example.com:8080/openam branch mainbranch sun.authlevel 0
Chapter 11. Using the OpenAM C API
Important
This samples mentioned in this chapter are not available in the current release.
This chapter introduces OpenAM C SDK. OpenAM C SDK is delivered for
selected platforms in
libraries/native/agent-csdk/agent-csdk.zip where you
unpacked the full version of OpenAM. To prepare to install OpenAM C SDK, first
unzip agent-csdk.zip.
$ unzip ~/Downloads/opensso/libraries/native/agent-csdk/agent-csdk.zip Archive: ~/Downloads/opensso/libraries/native/agent-csdk/agent-csdk.zip inflating: README inflating: agent-csdk-linux-32.tar.gz inflating: agent-csdk-linux-64.tar.gz inflating: agent-csdk-solaris-sparc-32.tar.gz inflating: agent-csdk-solaris-sparc-64.tar.gz inflating: agent-csdk-solaris-x86-32.tar.gz inflating: agent-csdk-solaris-x86-64.tar.gz extracting: agent-csdk-windows-32.zip extracting: agent-csdk-windows-64.zip
Unpack the archive for your platform.
$ mkdir -p /path/to/openam-client ; cd /path/to/openam-client $ tar xzvf /path/to/agent-csdk-linux-32.tar.gz

Chapter 12. Extending OpenAM
OpenAM services solve a wide range of access and federation management problems out of the box. Yet, OpenAM also exposes APIs and SPIs that enable you extend OpenAM services when built-in functionality does not fit your deployment.
This part of the guide covers OpenAM mechanisms for plugging in additional functionality not available out of the box.
Chapter 13. Customizing Profile Attributes
You can extend user profiles by adding custom attributes. This chapter demonstrates how to add a custom attribute to a user profile when storing user profiles in the embedded LDAP directory.
Adding a custom attribute involves both updating the
iPlanetAMUserService, and also updating the identity
repository schema to hold the new attribute. Furthermore, to allow users
to update the attribute in their own profiles, you must also update the
OpenAM policy configuration stored in the configuration directory.
Follow the steps below to create a custom attribute in OpenAM.
Create a backup copy of the configuration file for the
iPlanetAmUserService.$ cd $HOME $ cp openam/config/xml/amUser.xml openam/config/xml/amUser.xml.orig
Edit the file to add your attribute as one of the list of
<User>attributes.<AttributeSchema name="customAttribute" type="single" syntax="string" any="display" i18nKey="Custom Attribute"> </AttributeSchema>Here, the name refers to the attribute type name used in LDAP. The
i18nKeyholds either the reference, or in this case the content, of the text that appears in the user interface.Delete
iPlanetAMUserService, and then create it from your updated configuration file.$ cd /path/to/tools/openam/bin/ $ ssoadm delete-svc --adminid amadmin --password-file /tmp/pwd.txt --servicename iPlanetAMUserService Service was deleted. $ ssoadm create-svc --adminid amadmin --password-file /tmp/pwd.txt --xmlfile $HOME/openam/config/xml/amUser.xml Service was added.
Follow the steps below to update the identity repository LDAP schema for the custom attribute, and then update OpenAM to use the custom attribute and object class.
Tip

Chapter 14. Customizing OAuth 2.0 Scope Handling
RFC 6749, The OAuth 2.0 Authorization Framework, describes access token scopes as a set of case-sensitive strings defined by the authorization server. Clients can request scopes, and resource owners can authorize them.
The default scopes implementation in OpenAM treats scopes as profile
attributes for the resource owner. When a resource server or other entity uses
the access token to get token information from OpenAM, OpenAM populates the
scopes with profile attribute values. For example, if one of the scopes
is mail, OpenAM sets mail to the
resource owner's email address in the token information returned.
You can change this behavior by writing your own scopes plugin. This chapter shows how to write a custom OAuth 2.0 scopes plugin for use in an OAuth 2.0 provider (authorization server) configuration.
14.1. Designing an OAuth 2.0 Scopes Plugin
A scopes plugin implements the
org.forgerock.openam.oauth2.provider.Scope interface. The
Scope interface has four methods that your plugin
overrides.
public Set<String> scopeToPresentOnAuthorizationPage(
Set<String> requestedScope,
Set<String> availableScopes,
Set<String> defaultScopes);
public Set<String> scopeRequestedForAccessToken(
Set<String> requestedScope,
Set<String> availableScopes,
Set<String> defaultScopes);
public Set<String> scopeRequestedForRefreshToken(
Set<String> requestedScope,
Set<String> availableScopes,
Set<String> allScopes,
Set<String> defaultScopes);
public Map<String, Object> evaluateScope(AccessToken token);The first three methods return the scopes to display when the resource
owner makes the authorization decision, or when an access token or refresh
token is granted, respectively. The fourth method,
evaluateScope can be used to set values for scopes
returned when token information is requested.
The following example plugin sets whether read and
write permissions were granted.
package org.forgerock.openam.examples;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;
import org.forgerock.openam.oauth2.model.AccessToken;
import org.forgerock.openam.oauth2.provider.Scope;
/**
* Custom scope providers implement the
* {@link org.forgerock.openam.oauth2.provider.Scope} interface.
*
* This custom scope implementation follows the OpenAM default scope
* implementation for all methods except {@link #evaluateScope}.
*
* The {@code evaluateScope} method is called when a client accesses
* the {@code /tokeninfo} endpoint to retrieve token information.
*
* In this example, the method populates scope values returned in the
* JSON with the token information.
*/
public class CustomScope implements Scope {
@Override
public Set<String> scopeToPresentOnAuthorizationPage(
Set<String> requestedScope,
Set<String> availableScopes,
Set<String> defaultScopes) {
if (requestedScope == null) {
return defaultScopes;
}
Set<String> scopes = new HashSet<String>(availableScopes);
scopes.retainAll(requestedScope);
return scopes;
}
@Override
public Set<String> scopeRequestedForAccessToken(
Set<String> requestedScope,
Set<String> availableScopes,
Set<String> defaultScopes) {
if (requestedScope == null){
return defaultScopes;
}
Set<String> scopes = new HashSet<String>(availableScopes);
scopes.retainAll(requestedScope);
return scopes;
}
@Override
public Set<String> scopeRequestedForRefreshToken(
Set<String> requestedScope,
Set<String> availableScopes,
Set<String> allScopes,
Set<String> defaultScopes) {
if (requestedScope == null){
return defaultScopes;
}
Set<String> scopes = new HashSet<String>(availableScopes);
scopes.retainAll(requestedScope);
return scopes;
}
@Override
public Map<String, Object> evaluateScope(AccessToken token) {
Set<String> scopes = token.getScope();
Map<String, Object> map = new HashMap<String, Object>();
String[] permissions = {"read", "write"};
for (String scope : permissions) {
if (scopes.contains(scope)) {
map.put(scope, true);
} else {
map.put(scope, false);
}
}
return map;
}
}14.2. Building an OAuth 2.0 Scopes Plugin
As the plugin imports at least
org.forgerock.openam.oauth2.model.AccessToken
and org.forgerock.openam.oauth2.provider.Scope, add
openam-oauth2-common-10.1.0-Xpress.jar to
the classpath.
After compiling, put it in a .jar file that you can deploy with OpenAM.
$ mkdir classes $ javac -d classes -cp /path/to/.../openam/WEB-INF/lib/openam-oauth2-common-10.1.0-Xpress.jar CustomScope.java $ cd classes/ $ jar cf ../CustomScope.jar
14.3. Configuring OpenAM to Use the Plugin
After building your plugin jar file, add the file under
WEB-INF/lib/ where you deployed OpenAM.
Restart OpenAM.
In OpenAM console, you can either configure a specific OAuth 2.0 provider to use your plugin, or configure your plugin as the default for new OAuth 2.0 providers. To configure a specific OAuth 2.0 provider to use your plugin, add the class name of your scopes plugin under Access Control > Realm Name > Services > OAuth2 Provider Name > Scope Implementation Class. To configure your plugin as the default for new providers, add the class name of your scopes plugin under Configuration > Global > OAuth2 Provider > Scope Implementation Class.
14.4. Trying the Example Plugin
If you build the example plugin shown above in
Section 14.1, "Designing an OAuth 2.0 Scopes Plugin", and then create an OAuth 2.0
client that takes scopes read and write,
you can configure OpenAM to use the plugin, and then try it as shown in the
following example.
$ curl
-d "grant_type=client_credentials&username=demo&password=changeit
&client_id=myClientID&client_secret=password&scope=read"
http://oauth2.example.com:8080/openam/oauth2/access_token
{
"expires_in": 599,
"token_type": "Bearer",
"access_token": "84122d5e-0462-4d81-93c3-7bc58bd416b3"
}
$ curl http://oauth2.example.com:8080/openam/oauth2/tokeninfo
?access_token=84122d5e-0462-4d81-93c3-7bc58bd416b3
{
"write": false,
"read": true,
"token_type": "Bearer",
"expires_in": 539,
"access_token": "84122d5e-0462-4d81-93c3-7bc58bd416b3"
}Chapter 15. Customizing Authentication Modules
This chapter shows how to customize authentication with a sample custom authentication module. For deployments with particular requirements not met by existing OpenAM authentication modules, determine whether you can adapt one of the built-in or extension modules for your needs. If not, build the functionality into a custom authentication module.
15.1. About the Sample Authentication Module
The sample authentication module prompts for a user name and password to authenticate the user, and handles error conditions. The sample shows how you integrate an authentication module into OpenAM such that you can configure the module through OpenAM console, and also localize the user interface.
The name for the sample authentication module is
SampleAuth. Notice how this name is used to form module
component names according to OpenAM conventions.
An OpenAM authentication module is comprised of five components.
The authentication logic, which is a class that extends the
com.sun.identity.authentication.spi.AMLoginModuleclass. In this case,SampleAuth.java.The principal, which is a class that implements the
java.security.Principalinterface. In this case,SampleAuthPrincipal.java.The callbacks XML file, which describes the states of authentication logic and the user input needed for each state. In this case there is one file,
SampleAuth.xml.The service configuration XML file, which defines how the authentication module is configured in OpenAM. In this case,
amAuthSampleAuth.xml.The properties files for the module, which map localized strings to identifiers used elsewhere in the module. In this case,
amAuthSampleAuth.properties.
15.2. The Sample Auth Callbacks
OpenAM callbacks XML files prompt the user for identity information
needed to process the authentication. The document type for a callback XML
file is described in
war-file-name/WEB-INF/Auth_Module_Properties.dtd.
Tip
Callback files for built-in modules are under
war-file-name/config/auth/default/;
extension modules are stored in the OpenAM source tree.
This example shows a simplified sample auth callbacks XML file that does no error handling. The file specifies only one state (order="1"), and prompts the user for two pieces of information: user name and password. All strings for the user interface are hard coded into the file.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ModuleProperties PUBLIC
"=//iPlanet//Authentication Module Properties XML Interface 1.0 DTD//EN"
"jar://com/sun/identity/authentication/Auth_Module_Properties.dtd">
<ModuleProperties moduleName="SampleAuth" version="1.0" >
<Callbacks length="2" order="1" timeout="600" header="Please Login" >
<NameCallback isRequired="true">
<Prompt> User Name: </Prompt>
</NameCallback>
<PasswordCallback echoPassword="false" >
<Prompt> Password: </Prompt>
</PasswordCallback>
</Callbacks>
</ModuleProperties>This example shows a full callbacks file with dynamic text and error
handling. Use this as your SimpleAuth.xml file.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ModuleProperties PUBLIC
"=//iPlanet//Authentication Module Properties XML Interface 1.0 DTD//EN"
"jar://com/sun/identity/authentication/Auth_Module_Properties.dtd">
<ModuleProperties moduleName="SampleAuth" version="1.0" >
<Callbacks length="0" order="1" timeout="600" header="#NOT SHOWN#" />
<Callbacks length="2" order="2" timeout="600" header="#TO BE SUBSTITUTED#">
<NameCallback isRequired="true">
<Prompt>#USERNAME#</Prompt>
</NameCallback>
<PasswordCallback echoPassword="false" >
<Prompt>#PASSWORD#</Prompt>
</PasswordCallback>
</Callbacks>
<Callbacks length="1" order="3" timeout="600" header="#TO BE SUBSTITUTED#"
error="true" >
<NameCallback>
<Prompt>#THE DUMMY WILL NEVER BE SHOWN#</Prompt>
</NameCallback>
</Callbacks>
</ModuleProperties>This file specifies three states.
The initial state (order="1") is used dynamically to replace the dummy strings shown between hashes (for example,
#USERNAME#) by thesubstituteUIStrings()method inSampleAuth.java.The next state (order="2") handles prompting the user for authentication information.
The last state (order="3") has the attribute
error="true". If the authentication module state machine reaches this order then the authentication has failed. TheNameCallbackis not used and not displayed to user. OpenAM requires that the callbacks array have at least one element. Otherwise OpenAM does not permit header substitution.
15.3. The Sample Authentication Logic
An OpenAM authentication module must extend the
com.sun.identity.authentication.spi.AMLoginModule abstract
class, and must implement the methods shown below.
See the OpenAM Java SDK API Specification for reference.
// OpenAM calls the init() method once when the module is created. public void init(Subject subject, Map sharedState, Map options) // OpenAM calls the process() method when the user submits authentication // information. The process() method determines what happens next: // success, failure, or the next state specified by the order // attribute in the callbacks XML file. public int process(Callback[] callbacks, int state) throws LoginException // OpenAM expects the getPrincipal() method to return an implementation of // the java.security.Principal interface. public Principal getPrincipal()
OpenAM does not reuse authentication module instances. This means that you can store information specific to the authentication process in the instance.
The implementation, SimpleAuth.java, is shown
below.

}15.5. The Sample Auth Service Configuration
OpenAM requires that all authentication modules be configured by means
of an OpenAM service. At minimum, the service must include an authentication
level attribute. Your module can access these configuration attributes in
the options parameter passed to the
init() method.
Some observations about the service configuration file follow in the list below.
The document type for a service configuration file is described in
war-file-name/WEB-INF/sms.dtd.The service name is taken from the module name:
iPlanetAMAuthmodule-nameService. In this case, the service name isiPlanetAMAuthSampleAuthService.The service must have a localized description, retrieved from a properties file.
The
i18nFileNameattribute in the service configuration holds the default (non-localized) base name of the Java properties file. Thei18nKeyattributes indicate properties keys to string values in the Java properties file.The authentication level attribute name is taken from the module name:
iplanet-am-auth-module-name-auth-level, where the module-name is all lower case. Here, the authentication level attribute is namediplanet-am-auth-sampleauth-auth-level.The Sample Auth service configuration includes an example
sampleauth-service-specific-attribute, which can be configured through OpenAM console.
The service configuration file,
amAuthSampleAuth.xml, is shown below.

OpenAM uses a Java properties file per locale to retrieve the
appropriate, localized strings for the authentication module. The default
properties file,
amAuthSampleAuth.properties, is shown below.
sampleauth-service-description=Sample Authentication Module a500=Authentication Level a501=Service Specific Attribute sampleauth-ui-login-header=Login sampleauth-ui-username-prompt=User Name: sampleauth-ui-password-prompt=Password: sampleauth-error-1=Error 1 occured during the authentication sampleauth-error-2=Error 2 occured during the authentication
15.7. Building & Installing the Sample Auth Module
Once you have the files for the sample authentication module, build the module, and then install the module into OpenAM.
15.7.1. Building the Module
The sample authentication module code relies on three .jar files, two of which are deployed with OpenAM, and the third which is provided by your web application container.
amserver.jarWhen you deploy OpenAM, the file is
war-file-name/WEB-INF/lib/amserver.jar.opensso-sharedlib.jarWhen you deploy OpenAM, the file is
war-file-name/WEB-INF/lib/opensso-sharedlib.jar.servlet-api.jarThis .jar provides the Java EE Servlet API.
If you use Apache Tomcat as your web application container, the file is
/path/to/tomcat/lib/servlet-api.jar.
Put these libraries for example in a lib/
directory, and then put them on your CLASSPATH to compile the custom
authentication authentication module classes.
$ mkdir classes $ javac -d classes -cp lib/servlet-api.jar:lib/amserver.jar: lib/opensso-sharedlib.jar src/com/forgerock/openam/examples/SampleAuth*.java
Add the resulting classes to a new sampleauth.jar
file.
$ cd classes/ $ jar cf ../sampleauth.jar .
15.7.2. Installing the Module
Installing the sample authentication module consists of putting the .jar and other files in the right places, registering the module with OpenAM, and then restarting the web application or the web application container.
Copy the sampleauth.jar file to
war-file-name/WEB-INF/lib/
where OpenAM is deployed.
$ cp sampleauth.jar /path/to/tomcat/webapps/openam/WEB-INF/lib/
Copy the amAuthSampleAuth.properties file to
war-file-name/WEB-INF/classes/
where OpenAM is deployed.
$ cp amAuthSampleAuth.properties /path/to/tomcat/webapps/openam/WEB-INF/classes/
Copy the amAuthSampleAuth.xml service definition
file to
war-file-name/WEB-INF/classes/
where OpenAM is deployed.
$ cp amAuthSampleAuth.xml /path/to/tomcat/webapps/openam/WEB-INF/classes/
Copy the SimpleAuth.xml callbacks file to
war-file-name/config/auth/default/
where OpenAM is deployed.
$ cp SampleAuth.xml /path/to/tomcat/webapps/openam/config/auth/default/
Register the module with OpenAM using the ssoadm command.
$ ssoadm create-svc --adminid amadmin --password-file /tmp/pwd.txt --xmlfile amAuthSampleAuth.xml Service was added. $ ssoadm register-auth-module --adminid amadmin --password-file /tmp/pwd.txt --authmodule com.forgerock.openam.examples.SampleAuth Authentication module was registered.
See the ssoadm reference in the Reference a full list of Authentication Service Management subcommands.
Restart OpenAM, or the web applications container where it runs.
$ /path/to/tomcat/bin/shutdown.sh $ /path/to/tomcat/bin/startup.sh $ tail -1 /path/to/tomcat/logs/catalina.out INFO: Server startup in 32746 ms
15.8. Configuring & Testing the Sample Auth Module
Login to the console as OpenAM administrator,
amadmin, and browse to Access Control >
Realm Name > Authentication > Module
Instances. Click New, and then create an instance of your Sample
Authentication Module.
After creating the module, click the name in the Module Instances list, and configure as appropriate.
Add your module to the top of the default authentication chain so that OpenAM considers the module sufficient to login. Also, under All Core Settings... for the realm, set User Profile creation to Dynamic so that successful login results
Now that your module is configured, logout of OpenAM console, to return to the login page.
You can try different combinations as seen in
SimpleAuth.java. Unless you create a
test subject with a user profile in OpenAM or set User
Profile creation to Dynamic for the login realm, successful login results
in an "User has no profile in this organization" error. This is because
OpenAM attempts to redirect the authenticated test user to a profile page
that does not exist.
Chapter 16. Creating a Post Authentication Plugin
Post authentication plugins (PAP) let you include custom processing at the end of the authentication process, immediately before the subject is authenticated. Common uses of post authentication plugins include setting cookies and session variables. Post authentication plugins are often used in conjunction with policy agents. The post authentication plugin sets custom session properties, and then the policy agent injects the custom properties into the request header to the protected application.
This chapter explains how to create a post authentication plugin.
16.1. Designing Your Post Authentication Plugin
Your post authentication plugin class implements the
AMPostAuthProcessInterface interface, and in particular
the following three methods.
public void onLoginSuccess( Map requestParamsMap, HttpServletRequest request, HttpServletResponse response, SSOToken token ) throws AuthenticationException public void onLoginFailure( Map requestParamsMap, HttpServletRequest request, HttpServletResponse response ) throws AuthenticationException public void onLogout( HttpServletRequest request, HttpServletResponse response, SSOToken token ) throws AuthenticationException
OpenAM calls the onLoginSuccess() and
onLoginFailure() methods immediately before informing the
user of login success or failure, respectively. OpenAM calls the
onLogout() method only when the user actively logs out,
not when a user's session times out.
See the OpenAM Java SDK API Specification for reference.
These methods can perform whatever processing you require. Yet, know that OpenAM calls your methods synchronously as part of the authentication process. Therefore, if your methods take a long time to complete, you will keep users waiting. Minimize the processing done in your post authentication methods.
16.2. Building Your Sample Post Authentication Plugin
The following example post authentication plugin sets a session property during successful login, writing to its debug log if the operation fails.
package com.forgerock.openam.examples;
import java.util.Map;
import com.iplanet.sso.SSOException;
import com.iplanet.sso.SSOToken;
import com.sun.identity.authentication.spi.AMPostAuthProcessInterface;
import com.sun.identity.authentication.spi.AuthenticationException;
import com.sun.identity.shared.debug.Debug;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class SamplePAP implements AMPostAuthProcessInterface
{
private final static String PROP_NAME = "MyProperty";
private final static String PROP_VALUE = "MyValue";
private final static String DEBUG_FILE = "SamplePAP";
protected Debug debug = Debug.getInstance(DEBUG_FILE);
public void onLoginSuccess(
Map requestParamsMap,
HttpServletRequest request,
HttpServletResponse response,
SSOToken token
) throws AuthenticationException
{
try {
token.setProperty(PROP_NAME, PROP_VALUE);
} catch (SSOException ssoe) {
debug.error("Unable to set property");
}
}
public void onLoginFailure(
Map requestParamsMap,
HttpServletRequest request,
HttpServletResponse response
) throws AuthenticationException
{
; // Not used
}
public void onLogout(
HttpServletRequest request,
HttpServletResponse response,
SSOToken token
) throws AuthenticationException
{
; // Not used
}
}A post authentication plugin code relies on three .jar files, two of which are deployed with OpenAM, and the third which is provided by your web application container.
amserver.jarWhen you deploy OpenAM, the file is
war-file-name/WEB-INF/lib/amserver.jar.opensso-sharedlib.jarWhen you deploy OpenAM, the file is
war-file-name/WEB-INF/lib/opensso-sharedlib.jar.servlet-api.jarThis .jar provides the Java EE Servlet API.
If you use Apache Tomcat as your web application container, the file is
/path/to/tomcat/lib/servlet-api.jar.
Put the sample plugin in
src/com/forgerock/openam/examples/SamplePAP.java,
and compile the class.
$ cd src $ mkdir ../classes $ javac -d ../classes -classpath /path/to/tomcat/webapps/openam/WEB-INF/lib/amserver.jar: /path/to/tomcat/webapps/openam/WEB-INF/lib/opensso-sharedlib.jar: /path/to/tomcat/lib/servlet-api.jar com/forgerock/openam/examples/SamplePAP.java
Copy the classes to the WEB-INF/classes directory
where you deployed OpenAM.
$ cp -r ../classes/* /path/to/tomcat/webapps/openam/WEB-INF/classes/
Restart OpenAM or your web container to ensure the post authentication plugin class is loaded.
$ /etc/init.d/tomcat stop $ /etc/init.d/tomcat start $ tail -1 /path/to/tomcat/logs/catalina.out INFO: Server startup in 32070 ms
16.3. Configuring Your Post Authentication Plugin
You can configure the post authentication plugin for a realm, for a service (authentication chain), or for a role. Where you configure the plugin depends on the scope to which the plugin should apply. Configuring the plugin at the realm level as shown here, for example, ensures that OpenAM calls your plugin for all authentications to the realm.
In the OpenAM console, browse to Access Control > Realm
Name > Authentication > All Core Settings... In the
Authentication Post Processing Classes list, add the sample plugin class,
com.forgerock.openam.examples.SamplePAP, and then click
Save.
Alternatively, you can configure sample plugin for the realm by using the ssoadm command.
$ ssoadm set-svc-attrs --adminid amadmin --password-file /tmp/pwd.txt --servicename iPlanetAMAuthService --realm /realm --attributevalues iplanet-am-auth-post-login-process-class= com.forgerock.openam.examples.SamplePAP iPlanetAMAuthService under /realm was modified.
16.4. Testing Your Post Authentication Plugin
To test the sample post authentication plugin, login successfully to
OpenAM in the scope where the plugin is configured. For example, if you
configured your plugin for the realm, /realm, specify the
realm in the login URL.
http://openam.example.com:8080/openam/UI/Login?realm=realm
Although as a user you do not notice anywhere in the user interface that OpenAM calls your plugin, a policy agent or custom client code could retrieve the session property your plugin added to the user session.
Chapter 17. Customizing Policy Evaluation
OpenAM policies let you restrict access to resources based both on identity and group membership, and also on a range of conditions including session age, authentication chain or module used, authentication level, realm, session properties, IP address and DNS name, user profile content, resource environment, date, day, time of day, and time zone. Yet, some deployments require further distinctions for policy evaluation. This chapter explains how to customize policy evaluation for deployments with particular requirements not met by built-in OpenAM functionality.
OpenAM comes with sample plugins that demonstrate how to customize policy evaluation. This chapter shows how to compile the samples, and how to configure OpenAM to use one of the plugins.
17.1. About the Sample Plugins
The OpenAM policy framework lets you build plugins to extend subjects,
conditions, and response providers for policies, and also extend referrals
for policy delegation. When you deploy OpenAM, you find Java code for sample
policy evaluation plugins under
war-file-name/source/com/sun/identity/samples/policy.
SampleCondition.javaExtends the
Conditioninterface. Shows an implementation of a condition to base the policy decision on the length of the user name.SampleReferral.javaExtends the
Referralinterface. Shows an implementation of a policy referral for delegation.SampleResponseProvider.javaExtends the
ResponseProviderinterface. Shows an implementation of a response provider to send an attribute from the user profile with the response.SampleSubject.javaExtends the
Subjectinterface. Shows an implementation that defines the users to whom the policy applies, in this case all authenticated users.
Before including the plugins in OpenAM, you compile the four files, and package the classes into a .jar for deployment.
The sample policy evaluation code relies on two .jar files deployed with OpenAM.
openam-core-10.1.0.jarWhen you deploy OpenAM, the file is
war-file-name/WEB-INF/lib/openam-core-10.1.0.jar.openam-shared-10.1.0.jarWhen you deploy OpenAM, the file is
war-file-name/WEB-INF/lib/openam-shared-10.1.0.jar.
$ cd /path/to/tomcat/webapps/openam/ $ mkdir classes $ javac -d classes -classpath /path/to/tomcat/webapps/openam/WEB-INF/lib/openam-core-10.1.0.jar: /path/to/tomcat/webapps/openam/WEB-INF/lib/openam-shared-10.1.0.jar source/com/sun/identity/samples/policy/Sample*.java $ cd classes/ $ jar cf ../policy-plugins.jar .
The .jar belongs under
war-file-name/WEB-INF/lib/.
$ cp ../policy-plugins.jar /path/to/tomcat/webapps/openam/WEB-INF/lib
Alternatively, you can add individual classes under
war-file-name/WEB-INF/classes/.
17.2. Configuring A Sample Policy Plugin
This section shows how to configure the sample custom policy condition
that you built. Configuration involves defining the strings that describe
the policy condition, and plugging the policy condition into the
iPlanetAMPolicyService, and then restarting OpenAM in
order to be able to add the condition to your policies.
The strings describing your plugin belong as properties values in two
files,
war-file-name/WEB-INF/classes/amPolicy.properties
and
war-file-name/WEB-INF/classes/amPolicyConfig.properties.
To the former, add this property:
samplecondition-policy-name=Sample Condition
To the later, add this property:
x100=Sample Condition
Add the schema that describes your plugin to OpenAM.
$ ssoadm add-plugin-schema --adminid amadmin --password-file /tmp/pwd.txt --servicename iPlanetAMPolicyService --interfacename Condition --pluginname SampleCondition --i18nname amPolicy --i18nkey samplecondition-policy-name --classname com.sun.identity.samples.policy.SampleCondition Plug-in schema, Condition was added to service, iPlanetAMPolicyService.
Set the choice values of the schema to include your plugin with other policy conditions in the policy service.
$ ssoadm set-attr-choicevals --adminid amadmin --password-file /tmp/pwd.txt --servicename iPlanetAMPolicyConfigService --schematype Organization --attributename iplanet-am-policy-selected-conditions --add --choicevalues "x100=Sample Condition" Choice Values were set.
Set the plugin policy condition as one of the default attibutes of the policy service.
$ ssoadm add-attr-defs --adminid amadmin --password-file /tmp/pwd.txt --servicename iPlanetAMPolicyConfigService --schematype Organization --attributevalues "iplanet-am-policy-selected-conditions=Sample Condition" Schema attribute defaults were added.
After completing configuration, restart OpenAM or the web application container.
$ /etc/init.d/tomcat stop Password: Using CATALINA_BASE: /path/to/tomcat Using CATALINA_HOME: /path/to/tomcat Using CATALINA_TMPDIR: /path/to/tomcat/temp Using JRE_HOME: /path/to/jdk1.6/jre Using CLASSPATH: /path/to/tomcat/bin/bootstrap.jar: /path/to/tomcat/bin/tomcat-juli.jar $ /etc/init.d/tomcat start Password: Using CATALINA_BASE: /path/to/tomcat Using CATALINA_HOME: /path/to/tomcat Using CATALINA_TMPDIR: /path/to/tomcat/temp Using JRE_HOME: /path/to/jdk1.6/jre Using CLASSPATH: /path/to/tomcat/bin/bootstrap.jar: /path/to/tomcat/bin/tomcat-juli.jar
In OpenAM console, browse to Access Control > Realm Name > Policies > Policy Name > Conditions > New... Notice in the list of conditions that you can now apply your Sample Condition.
Chapter 18. Customizing Identity Data Storage
OpenAM maps user and group identities into a realm using data stores. An OpenAM data store relies on a Java identity repository (IdRepo) plugin to implement interaction with the identity repository where the users and groups are stored.
18.1. About the Identity Repository Plugin
This chapter describes how to create a custom identity repository plugin. OpenAM includes built-in support for LDAP and JDBC identity repositories. For most deployments, you therefore do not need to create your own custom identity repository plugin. Only create custom identity repository plugins for deployments with particular requirements not met by built-in OpenAM functionality.
Tip
Before creating your own identity repository plugin, start by reading
the OpenAM source code for the FilesRepo or
DatabaseRepo plugins under
com.sun.identity.idm.plugins.
18.1.1. IdRepo Inheritance
Your identity repository plugin class must extend the
com.sun.identity.idm.IdRepo abstract class, and must
include a constructor method that takes no arguments.
18.1.2. IdRepo Lifecycle
When OpenAM instantiates your IdRepo plugin, it calls the
initialize() method.
public void initialize(Map configParams)
The configParams are service configuration
parameters for the realm where the IdRepo plugin is configured. The
configParams normally serve to set up communication with
the underlying identity data store. OpenAM calls the
initialize() method once, and considers the identity
repository ready for use.
If you encounter errors or exceptions during initialization, catch and store them in your plugin for use later when OpenAM calls other plugin methods.
After initialization, OpenAM calls the addListener()
and removeListener() methods to register listeners that
inform OpenAM client code of changes to identities managed by your
IdRepo.
public int addListener(SSOToken token, IdRepoListener listener) public void removeListener()
You must handle listener registration in your IdRepo plugin, and also
return events to OpenAM through the IdRepoListener.
When stopping, OpenAM calls your IdRepo plugin
shutdown() method.
public void shutdown()
You are not required to implement shutdown() unless
your IdRepo plugin has shut down work of its own to do, such as close
connections to the underlying identity data store.
18.1.3. IdRepo Plugin Capabilities
Your IdRepo plugin provides OpenAM with a generic means to manage subjects—including users and groups but also special types such as roles, realms, and agents— and to create, read, update, delete, and search subjects. In order for OpenAM to determine your plugin's capabilities, it calls the methods described in this section.
public Set getSupportedTypes()
The getSupportedTypes() method returns a set of
IdType objects, such as IdType.USER
and IdType.GROUP. You can either hard-code the supported
types into your plugin, or make them configurable through the IdRepo
service.
public Set getSupportedOperations(IdType type)
The getSupportedOperations() method returns a set
of IdOperation objects, such as
IdOperation.CREATE and
IdOperation.EDIT. You can also either hard-code these, or
make them configurable.
public boolean supportsAuthentication()
The supportsAuthentication() method returns true if
your plugin supports the authenticate() method.
18.2. Identity Repository Plugin Implementation
Your IdRepo plugin implements operational methods depending on what you support. These methods perform the operations in your data store.
- Create
OpenAM calls
create()to provision a new identity in the repository, wherenameis the new identity's name, andattrMapholds the attributes names and values.public String create(SSOToken token, IdType type, String name, Map attrMap) throws IdRepoException, SSOException
- Read
OpenAM calls the following methods to retrieve subjects in the identity repository, and to check account activity. If your data store does not support binary attributes, return an empty
MapforgetBinaryAttributes().public boolean isExists( SSOToken token, IdType type, String name ) throws IdRepoException, SSOException public boolean isActive( SSOToken token, IdType type, String name ) throws IdRepoException, SSOException public Map getAttributes( SSOToken token, IdType type, String name ) throws IdRepoException, SSOException public Map getAttributes( SSOToken token, IdType type, String name, Set attrNames ) throws IdRepoException, SSOException public Map getBinaryAttributes( SSOToken token, IdType type, String name, Set attrNames ) throws IdRepoException, SSOException public RepoSearchResults search( SSOToken token, IdType type, String pattern, Map avPairs, boolean recursive, int maxResults, int maxTime, Set returnAttrs ) throws IdRepoException, SSOException public RepoSearchResults search( SSOToken token, IdType type, String pattern, int maxTime, int maxResults, Set returnAttrs, boolean returnAllAttrs, int filterOp, Map avPairs, boolean recursive ) throws IdRepoException, SSOException
- Edit
OpenAM calls the following methods to update a subject in the identity repository.
public void setAttributes( SSOToken token, IdType type, String name, Map attributes, boolean isAdd ) throws IdRepoException, SSOException public void setBinaryAttributes( SSOToken token, IdType type, String name, Map attributes, boolean isAdd ) throws IdRepoException, SSOException public void removeAttributes( SSOToken token, IdType type, String name, Set attrNames ) throws IdRepoException, SSOException public void modifyMemberShip( SSOToken token, IdType type, String name, Set members, IdType membersType, int operation ) throws IdRepoException, SSOException public void setActiveStatus( SSOToken token, IdType type, String name, boolean active )
- Authenticate
OpenAM calls
authenticate()with the credentials from theDataStoreauthentication module.public boolean authenticate(Callback[] credentials) throws IdRepoException, AuthLoginException
- Delete
The
delete()method removes the subject from the identity repository. Thenamespecifies the subject.public void delete(SSOToken token, IdType type, String name) throws IdRepoException, SSOException
- Service
The
IdOperation.SERVICEoperation is rarely used in recent OpenAM deployments.
18.3. Identity Repository Plugin Deployment
Your IdRepo plugin must link to amserver.jar,
which when you deploy OpenAM is
war-file-name/WEB-INF/lib/amserver.jar.
You can either package your plugin as a .jar, and then add it to
war-file-name/WEB-INF/lib/,
or add the classes under
war-file-name/WEB-INF/classes/.
To register your plugin with OpenAM, you add a
SubSchema to the
sunIdentityRepositoryService using the
ssoadm command. First, you create the
SubSchema document having the following structure.
<SubSchema i18nKey="x4000" inheritance="multiple" maintainPriority="no"
name="CustomRepo" supportsApplicableOrganization="no" validate="yes">
<AttributeSchema cosQualifier="default" isSearchable="no"
name="RequiredValueValidator" syntax="string"
type="validator" >
<DefaultValues>
<Value>com.sun.identity.sm.RequiredValueValidator</Value>
</DefaultValues>
</AttributeSchema>
<AttributeSchema any="required" cosQualifier="default"
i18nKey="x4001" isSearchable="no"
name="sunIdRepoClass" syntax="string"
type="single" validator="RequiredValueValidator" >
<DefaultValues>
<Value>org.test.CustomRepo</Value>
</DefaultValues>
</AttributeSchema>
<AttributeSchema cosQualifier="default" i18nKey="x4002" isSearchable="no"
name="sunIdRepoAttributeMapping" syntax="string" type="list">
<DefaultValues>
<Value></Value>
</DefaultValues>
</AttributeSchema>
</SubSchema>Also include the AttributeSchema required to
configure your IdRepo plugin.
Notice the i18nKey attributes on
SubSchema elements. The i18nKey
attribute values correspond to properties in the
amIdRepoService.properties file, stored under
war-file-name/WEB-INF/classes/.
OpenAM console displays the label for the configuration user interface that
it retrieves from the value of the i18nKey property in the
amIdRepoService.properties file.
Register your plugin using the ssoadm command after copy the files into place.
$ ssoadm add-sub-schema --adminid amadmin --password-file /tmp/pwd.txt --servicename sunIdentityRepositoryService --schematype Organization --filename customIdRepo.xml --subschemaname CustomRepo
Login to OpenAM console as administrator, then then Browse to Access Control > Realm Name > Data Stores. In the Data Stores table, click New... to create a Data Store corresponding to your custom IdRepo plugin. In the first screen of the wizard, name the Data Store and select the type corresponding to your plugin. In the second screen of the wizard, add the configuration for your plugin.
After creating the Data Store, create a new subject in the realm to check that your plugin works as expected. You can do this under Access Control > Realm Name > Subjects.
If your plugin supports authentication, then users should now be able
to authenticate using the DataStore module for the
realm.
