This command is found on the Action menu; it is also the fourth button
(from the left) in the toolbar. Use this command to destroy all
of the Kerberos tickets (and perhaps AFS tokens) on your local
machine. Leash confirms your intentions before completing the
request. Tickets for individual services may not be destroyed by
the Leash Application.
Once tickets are destroyed, you must Get or Import new tickets before
Kerberized applications can once again access network services.
