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 contains  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  system.  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 termi-
     nal beep.

     If desired, you can  place  the  kdestroy  command  in  your
     .logout  file  so  that your tickets are destroyed automati-
     cally 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  kdes-
           troy fails to destroy the tickets.


ENVIRONMENT VARIABLES

     kdestroy uses the following environment variable:

      KRB5CCNAME
           Location of the credentials (ticket) cache.


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 des-
     troyed.   Separate  ticket  caches  are  used  to  hold root
     instance and password changing tickets. These  files  should
     probably be destroyed too, or all of a user's tickets should
     be kept in a single credential cache.
