    winbind: Retry after SESSION_EXPIRED error in ping-dc
    
    Trying to establish a netlogon connection when the service ticket
    expires might fail with NT_STATUS_NETWORK_SESSION_EXPIRED. The
    underlying client code already marks the session as invalid, so retry
    the netlogon connect in this case.
