    Contrary to all the other advice you've received, the cleanest way to
    have done this would be to read the man pages on pam_console (8) ,
    pam_console_apply (8), and console.apps (5). Proper settings will
    allow users logged in on the console (and only on the console) to
    simply shut down the machine with no need for sudo or any other
    rigamarole. This will also save you from mischief makers who could ssh
    into a machine while someone else is using it and then shut it down on
    them.

    HTH,
