  NAME
    kdestroy - Destroys a principal's login context and associated
               credentials

  SYNOPSIS

    kdestroy [-c cache_name]

  OPTIONS

    -c cache_name        Specifies that the login context and associated
                         credentials for cache_name should be destroyed
                         instead of the default cache.

  DESCRIPTION

  The kdestroy command destroys a principal's login context and the
  principal's credentials. Until the credentials are reestablished by
  either executing the dce_login command or the kinit command,  the
  principal and any processes created by the principal will be limited to
  unauthenticated access.

                       default credentials cache.
