      It does work without NIS/NIS+ (well sort of), it's just that you have to
    create an /etc/netid (see man netid for details) and /etc/publickey (man
    -s 4 publickey) files.  However, certain applications (dtpad, dtmail,
    mailtool, and some others) still won't run.  Also, I couldn't get a
    console root login to work under CDE either ... although some might
    consider this a plus.
    
      Now, I can't take credit for discovering this, that goes to Dan
    Astoorian who pointed this out to me in a related discussion.
    
      Also, Sun has issued the following bug id assoiciated with running
    ttsessoin with DES: 4272834
