kdestroy(1)                      User Commands                     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 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
                               kdestroy 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.
