Interface MessageConsumerPlugin

public interface MessageConsumerPlugin

The base interface for providing Message Consumer Extension functionality. This plug-in extends the SiteMinder SAML 1.x, SAML 2.0 and the WS-Federation authentication schemes.

To develop the plug-in implementation:

• The implementation class must provide a public default constructor, which has no parameters.
• The implementation must be stateless -- that is, the single plug-in instance can be concurrently used for many threads.

To integrate the MessageConsumerPlugin with the SiteMinder SAML or WS-Federation authentication scheme:

• Compile the MessageConsumerPlugin Java file. It requires the following dependent libraries installed with SiteMinder Policy Server:
  • <InstallationRoot>\siteminder\bin\jars\SmJavaApi.jar There is an identical copy of SmJavaApi.jar installed with SiteMinder SDK, <InstallationRoot>\sdk\java\SmJavaApi.jar. You can use either of them at development time.
• When a plug-in class is available, either in a folder or a jar file, modify the <InstallationRoot>\siteminder\config\JVMOptions.txt for the "-Djava.class.path" setting so that the plug-in class can be loaded with the modified classpath. Do not modify the ClassPath for the existing xerces.jar, xalan.jar, or SmJavaApi.jar.
• Restart the Policy Server.The Policy Server must be restarted to pick up the latest version of MessageConsumerPlugin each time the plug-in Java file is recompiled.
• Specify the full class name of the compiled plug-in in the SiteMinder Admin UI. Alternatively, you can use the Policy Management API (C or Perl) to set the IdpPluginClass and IdpPluginParameters.

Since:

SDK 6.0 SP3

Method Detail

init

boolean init(APIContext context)
             throws java.lang.Exception

Performs any initialization procedures that MessageConsumerPlugin requires.

SiteMinder calls this method when this MessageConsumerPlugin object is loaded. SiteMinder maintains a cache for all the instances, one instance per Policy Server. Each MessageConsumerPlugin is initialized only once.

Parameters:

context - A context object that provides methods for sending log, trace and error messages to the Policy Server.

Returns:

true if the initialization succeeds.

Throws:

java.lang.Exception - Thrown if anything happens unexpectedly; it is treated as an error.

release

boolean release(APIContext context)
                throws java.lang.Exception

Performs any close-down procedures that the MessageConsumerPlugin requires.

SiteMinder calls this method once for each instance of MessageConsumerPlugin class, when this object is unloaded, or SiteMinder is shutting down. SiteMinder maintains a cache for all the instances, one instance per Policy Server. Each MessageConsumerPlugin is released only once.

Parameters:

context - A context object that provides methods for sending log, trace and error messages to the Policy Server.

Returns:

true if the shutdown succeeds.

Throws:

java.lang.Exception - Thrown if anything happens unexpectedly; it is treated as an error.

postDisambiguateUser

int postDisambiguateUser(APIContext apiContext,
                         UserContext userContext,
                         java.lang.String parameters,
                         java.lang.String message,
                         java.util.Map props,
                         java.lang.String loginID,
                         java.lang.StringBuffer output)
                         throws java.lang.Exception

Performs additional user disambiguation. The Policy Server calls this method when the SAML authentication scheme cannot disambiguate the user. For SAML2.0, when encrypted data data (Assertion, Name ID, or Attribute) is used in an SSO transaction, the decrypted assertion can be retrieved by accessing the _DecryptedAssertion key of the props parameter.

Parameters:

apiContext - A context object that provides methods for sending log, trace, and error messages to the Policy Server.

userContext - A context object that provides directory information for user disambiguation.

parameters - The parameters string configured with the plug-in.

message - The federation message, which is the SAML Response element.

props - The Map object that contains all the name/value pair settings defined for the authentication scheme.

loginID - The available loginID, which can be used to search the user in the directory

output - The result buffer, which contains the user DN.

Returns:

The processing status, which is either an authentication reason code, or SUCCESS, or FAILURE. This return value is used as the real status for the SAML authentication scheme

Throws:

java.lang.Exception - Thrown when an error has occurred.

postAuthenticateUser

int postAuthenticateUser(APIContext apiContext,
                         java.lang.String parameters,
                         java.lang.String message,
                         java.util.Map props,
                         int statusCode)
                         throws java.lang.Exception

Performs customization of federation credential validation.

Parameters:

apiContext - A context object that provides methods for sending log, trace, and error messages to the Policy Server.

parameters - The parameters string configured with the plug-in.

message - The federation message, which is the SAML Response element

props - The Map object that contains all the name/value pair settings defined for the authentication scheme

statusCode - The current processing status.

Returns:

The processing status, which is either an authentication reason code, or SUCCESS, or FAILURE. This return value is used as the real status for the SAML authentication scheme.

Throws:

java.lang.Exception - Thrown when an error has occurred.
