Replica Synchronization

Replica synchronization ensures that changes to NDS* objects are synchronized among all replicas of the partition.

This means that any server that holds a copy of a given partition must communicate with the other servers to synchronize a change.

Two types of replica synchronization can occur:

• 'Immediate sync' occurs after any change to an NDS object, or any addition or deletion of an object in the Directory tree.
• 'Slow sync' occurs for specific changes to an NDS object that are repetitive and common to multiple objects such as changes to login properties. An example of this would be an update to Login Time, Last Login Time, Network Address, and Revision properties when a user logs in or out.

The slow sync process runs only in the absence of an immediate sync process. By default, the immediate sync process runs ten seconds after any change is saved and the slow sync runs 22 minutes after other changes are made.
