Replica Synchronization

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

This means that any server that holds a replica of a 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 a Directory object, or any addition or deletion of an object in the NDS tree. By default, the immediate sync process runs ten seconds after any change is saved. Immediate sync also applies to changes in Network Address and Revision attributes to the User object.
• Slow sync occurs for specific changes to a Directory object that are repetitive and common to multiple objects such as changes to login properties. An example of this would be a password change or an update to Login Time and Last Login Time attributes when a user logs in or out.

The slow sync process runs only in the absence of an immediate sync process, by default 30 minutes after particular changes are made.
