Starting with this release, J2EE agents provide support for user mapping modes that have flexibility in the user names they choose. In prior releases, a user name had to be an Access Manager user ID. Now, user names can be chosen from a few different sources as long as the names are for authenticated users who have trusted identities. A trusted identity can be established on the agent- protected server for a security principal (or for an equivalent trusted identity of the user). This mechanism allows the agent to choose a user ID for the authenticated user from the user’s profile attributes, the user’s session properties, or an HTTP header accompanying the user request.
