Replication and Data Integrity

Active Directory Domain Services provide multi-master update. Multi-master update means that all full replicas of a given partition are writable (the partial replicas on global catalog servers are not writable.) Multi-master update means that updates are not blocked even when some replicas are inoperable. The Active Directory server propagates the changes from the updated replica to all other replicas. Replication is automatic and transparent.
