Managing Users and Roles with the Directory Service
The directory service is intended to provide a single place for user and role management across multiple appliances. It does not matter which appliance that the changes are made to as any new changes are replicated to all other appliances added under Replication Management.
When you create or modify a user on one appliance, the changes automatically replicate to all other appliances participating in the replication. When you set up clustering, the nodes are automatically set up to replicate, so there is no need to manually add the other appliance in the cluster.
Select Add to add replication sources.
