During normal companion mode, companions automatically synchronize any changes to user logins, access and security information, and so on. Any logins added during failover are automatically added to the primary companion when it gets updated during failback. Any uncommitted transactions must be resubmitted and any options set at the session level must be reestablished once the companion has successfully failed-over.

All user roles and privileges are maintained after fail over.
