The sample deployment scenarios include:
■ “Multi-Master Replication Deployment” on page 140
■ “Multi-Host Deployment with Windows NT” on page 141
Multi-Master Replication Deployment
In a multi-master replication (MMR) deployment, two Directory Server instances are installed
on different hosts. It is possible to run the hosts on different operating systems, but in this
scenario, both hosts are running on the same operating system.
Table 7–1 and Figure 7–2 illustrate how the Identity Synchronization for Windows components
are distributed between the two hosts.
TABLE 7–1 Component Distribution in a Multi-Master Replication Deployment
Host 1 Host 2
Directory Server (one instance) as the secondary
master for synchronized users Directory Server (one instance) as the preferred
master for synchronized users
Core (Message Queue, Central Logger, System
Manager, and Console) Directory Server Plugin
Active Directory Connector

Directory Server Plugin
The migration process keeps on-demand password synchronization running continuously on
the preferred master or on the secondary master.
Note – If both hosts are running on a Solaris operating system, then a third host running
Windows 2000 with Active Directory is required for synchronization purposes only. (No
components would be installed on the third host.)
The following figure illustrates the process for migrating Identity Synchronization for Windows
in a MMR deployment.
