Identity management is the system service that provides definitive identity information for each user in a computing environment. That information is used to:

• Authenticate users, verifying that they are who they claim to be.

• Authorize users to access and perhaps modify system data or services. Authorization is granted, or denied, based on role and governance information that's also stored by the identity management system and associated with each user. For example, users with the role of administrator would generally be authorized to view and modify more information than non-administrators.

Java™ enterprise applications benefit from not only core identity management services, but also additional integration and federation of user identity provided by JBoss® Enterprise Portal Platform services. These services enable greatly enhanced user experiences with features like single sign-on (SSO) and comprehensive security for personal information.
