Multi-master replication (in ADAM)

A feature of Active Directory Application Mode that provides and maintains copies of the directory across multiple servers in a configuration set. Since all replicas of a given configuration set are writable, updates can be applied to any replica of a given partition in a replication set. The Active Directory Application Mode replication system propagates the changes from a given replica to all other replicas. Replication is automatic and transparent.

Active Directory Application Mode multi-master replication propagates every object created on any ADAM instance to each of the other participating ADAM instances that span a replica set. If one ADAM instance slows or fails, other ADAM instances in the same replica set can provide the necessary directory access because they contain the same directory data.
