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
