A connector instance handles both directory sync and authentication, or either one of them, based upon your configuration. In the event of a connector instance failure, authentication is handled automatically by another connector 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 another connector instance instead of the original connector instance. Directory sync can only be enabled on one connector at a time.
