In the event of a service instance failure, authentication is handled automatically by a cloned instance, as configured in the load balancer. However, for directory sync, you need to modify the directory settings in the VMware Identity Manager service to use a cloned instance. Directory sync is handled by the connector component of the service and can only be enabled on one connector at a time.
