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
