kdestroy - destroy Kerberos tickets
/usr/bin/kdestroy [-q] [-c cache_name]
The kdestroy utility destroys the user's active Kerberos authorization
tickets by writing zeros to the specified credentials cache that con-
tains them. If the credentials cache is not specified, the default cre-
dentials cache is destroyed. If the credentials cache does not exist,
kdestroy displays a message to that effect.
After overwriting the cache, kdestroy removes the cache from the sys-
tem. The utility displays a message indicating the success or failure
of the operation. If kdestroy is unable to destroy the cache, it will
warn you by making your terminal beep.
If desired, you can place the kdestroy command in your .logout file so
that your tickets are destroyed automatically when you logout.
The following options are supported:
-c cache_name Uses cache_name as the credentials (ticket)
cache name and location. If this option is not
used, the default cache name and location are
-q Runs quietly. Your terminal will not beep when
kdestroy fails to destroy the tickets.
kdestroy uses the following environment variable:
KRB5CCNAME Location of the credentials (ticket) cache. See
krb5envvar(5) for syntax and details.
/tmp/krb5cc_uid Default credentials cache (uid is the decimal
UID of the user).

Only the tickets in the specified credentials cache are destroyed. Sep-
arate ticket caches are used to hold root instance and password chang-
ing tickets. These files should probably be destroyed too, or all of a
user's tickets should be kept in a single credential cache.
