An identity repository is a database where you can store user attributes and user configuration data. Previous versions of Access Manager relied on Sun Java System Directory Server as the only supported identity repository and the only supported software for creating, managing, and storing user data.
Access Manager provides an identity repository plug-in that connects to an identity repository framework. This new model enables you to view and retrieve Access Manager user information without having to make changes in your existing user database. The Access Manager framework integrates data from the identity repository plug-in with data from other Access Manager plug-ins to form a virtual identity for each user. Access Manager can then use the universal identity in authentication and authorization processes among more than one identity repository. The virtual user identity is destroyed when the user’s session ends.
You can configure the Identity Repository Management Service per realm to use its own list of Identity Repositories.
Using realm-based configuration, you can specify a single Identity Repository that will store service configurations for both users and roles. The Identity Repository Service provides a list of Identity Repositories that can provide user attributes to Policy, SAML , and Liberty services. The Identity Repository Services pluggable interface combines attributes obtained from different repositories. Identity Repository plug-ins provide interfaces to create, read , edit, and delete objects such as Realm, Role, Group, User, and Agent.
The default identity repository plug-in is designed to work with Sun Java Directory Server which is based on LDAP. In previous Access Manager versions, the functionality of this default plug-in was provided by the AM SDK component. In Access Manager 7.0, the AM SDK functionality still exists, but now in plug-in form.
