Realm mode is based on the Access Manager information tree and Identity Repository Management Service described in previous sections. Realm Mode is appropriate in most new Access Manager deployments where you want to keep identity repositories independent of access management, or where you cannot maintain user data within the required object classes of Sun Java System Directory Server. If you choose Realm Mode at installation, your identity repositories can exist in any of the following configurations:
In the same Directory Server instance and the same suffix as the Access Manager information tree.
In the same Directory Server instance but in a different suffix as the Access Manager information tree.
In a different directory server instance from the Access Manager information tree.
