Abstract: A method and apparatus for managing a heterogeneous network is disclosed. A first computer system has one or more identities. A management service on a second computer system manages objects on the second computer system. One or more objects on the second computer system represent the one or more identities and are adapted to be managed by the management service. An event monitor operating on the second computer system is operative to send messages relating to changes to the one or more objects. A replication agent operating on the first computer system is operative to receive messages from the event monitor and is operative to synchronize the one or more identities to the changes made to the one or more objects.
