        TdbException -

        When requesting a new login ticket, the new ticket will replace any previous ticket assigned to the current user. Subsequent ticket-based login for the user must use the new ticket.

        The login ticket feature requries TRIPsystem 8.0 or later and must be explicitly enabled on the TRIP server in order to be used as it is disabled by default.

        Tickets time out after 30 days of inactivity by default. This period can be configured. Refer to the TRIPsystem documentation for more information.

        Parameters:
        ticket - Empty string or login ticket to revoke
