In multimaster replication (MMR) environments, Identity Synchronization for Windows allows you to specify a preferred and secondary master servers for any given Sun directory source.
Directory Server supports n-way MMR (where you can change the replicated database at any of the 'n' masters configured). When you install the plug-in at the preferred master, you must select the Other host type and enter Directory Server instance's parameters manually during plug-in installation.
The following steps assume you are replicating a single suffix. If you are replicating more than one suffix, you may configure them in parallel on each server. In other words, you may repeat each step to configure replication on multiple suffixes.
Define a replication manager entry on all servers except single masters (or use the default replication manager on all servers.)
On all servers containing a dedicated consumer replica:
On all servers containing a hub replica, if applicable:
On all servers containing a master replica:
Configure the replication agreements on all supplier replicas, in the following order:
Configure replication agreements between the hub replicas and their consumers.
For multimaster replication, initialize all masters from the same master replica containing the original copy of the data. Initialize the hub and consumer replicas.
