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 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.

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).

BUGS
       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.
