KDESTROY(1)KDESTROY(1)NAME
kdestroy - destroy Kerberos tickets
SYNOPSIS
/usr/bin/kdestroy [-q] [-c cache_name]
DESCRIPTION
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
credentials 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.
OPTIONS
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 used.
-q
Runs quietly. Your terminal will not beep when kde‐
stroy fails to destroy the tickets.
ENVIRONMENT VARIABLES
kdestroy uses the following environment variable:
KRB5CCNAME
Location of the credentials (ticket) cache. See
krb5envvar(5) for syntax and details.
FILES
/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.
