Enabling Replication Dialog
The replication wizard helps you to enable replication on a suffix or promote or demote the role of an enabled suffix. The first step is to choose the new role of your suffix:
Consumer Replica. Data below this suffix cannot be modified by LDAP clients. Data changes are not logged and cannot be replicated to other servers.
A consumer replica is a dedicated read-only copy of the suffix. It receives all updates to the suffix contents through replication. It automatically refers any write operations back to a master replica.
Master Replica. Data below this suffix can be modified by LDAP clients. Data changes are logged and may be replicated to other servers.
A master replica is the "owner" of the suffix contents: it centralizes all write operations and distributes them to consumer replicas of the suffix. In multi-master replication (MMR), several masters allow modifications to the same suffix and they use timestamps to determine the latest updates.
Hub Replica. Data below this suffix cannot be modified by LDAP clients. Data changes are logged and may be replicated to other servers.
A hub replica receives updates from masters (or another hub) and sends them to any number of consumers (or another hub). The hub replica is read-only, and like a consumer, it automatically refers any write operations back to a master replica.
