Sun Java System SAML v2 Plug-in for Federation Services User's Guide


The IDPAttributeMapper interface is used by the identity provider to specify which user attributes will be included in an assertion. The default implementation, com.sun.identity.saml2.plugins.DefaultIDPAttributeMapper, retrieves attribute mappings (SAML v2-attribute=user-attribute) defined in the attributeMap property in the identity provider's extended metadata configuration file. It reads the value of the user attribute from the identity provider's data store, and sets this value as the <AttributeValue> of the specified SAML v2 attribute. The SAML v2 attributes and values are then included in the <AttributeStatement> of the assertion and sent to the service provider. The value of attributeMap can be changed to modify the mapper's behavior without programming. The default mapper itself can be modified to attach any identity provider user attribute with additional programming.
