Replication allows write operations to be directed to any directory server in the topology. Distributing write
operations in a round-robin fashion could introduce conflicts. In particular, distributing
a series of LDAP
DN operations targeting the same distinguished name (DN) in quick succession
can cause conflicts that require manual intervention.
The Assured Replication feature can help prevent conflicts created by the same client application. For more information, see Configuring assured replication.
Consider using server affinity with the load balancer that either associates a client IP address or a client connection with a single directory server instance at a time.
For load balancing LDAP traffic, consider using the PingDirectoryProxy Server. The Server Affinity feature in PingDirectoryProxy Server enables replication-friendly load balancing. For more information, see Configuring server affinity.
