kdestroy(1)

NAME

   kdestroy - destroy Kerberos tickets

SYNOPSIS

   kdestroy [-A] [-q] [-c cache_name]

DESCRIPTION

   The  kdestroy utility destroys the user's active Kerberos authorization
   tickets by overwriting and deleting the credentials cache that contains
   them.    If  the  credentials  cache  is  not  specified,  the  default
   credentials cache is destroyed.

OPTIONS

   -A     Destroys all caches in the collection, if a cache collection  is
          available.

   -q     Run quietly.  Normally kdestroy beeps if it fails to destroy the
          user's tickets.  The -q flag suppresses this behavior.

   -c cache_name
          Use cache_name  as  the  credentials  (ticket)  cache  name  and
          location; if this option is not used, the default cache name and
          location are used.

          The default credentials cache may vary between systems.  If  the
          KRB5CCNAME  environment  variable  is  set, its value is used to
          name the default ticket cache.

NOTE

   Most installations recommend that you place  the  kdestroy  command  in
   your  .logout  file,  so  that your tickets are destroyed automatically
   when you log out.

ENVIRONMENT

   kdestroy uses the following environment variable:

   KRB5CCNAME
          Location of the default Kerberos 5 credentials  (ticket)  cache,
          in  the  form  type:residual.  If no type prefix is present, the
          FILE type is  assumed.   The  type  of  the  default  cache  may
          determine  the availability of a cache collection; for instance,
          a default cache of type DIR causes caches within  the  directory
          to be present in the collection.

FILES

   FILE:/tmp/krb5cc_%{uid}
          Default location of Kerberos 5 credentials cache
