i am not sure but i believe it should work

you can change the permission of shutdown
so that other users can also shutdown , without elevating their
previlages (and hope you dont need to create a user just for
shutdown :-) ).

what I do is create a 'shutdown' group, then modify /sbin/shutdown so that its group owner (set to 'shutdown') has executable permission, chmod /sbin/shutdown to suid ('chmod 4550 /sbin/shutdown') and add the desired user to the 'shutdown' group.

but that's just what I do, I could be wrong.

heh, i also configured sudo for it, i did it differently though, as i have only the root account and my own.
i just added this to the command alias thingie:
#Command Alias section
[your_username]            ALL=NOPASSWD:/sbin/shutdown
i just hope i did it the best way....

: he doesnt want to give the root passwd to the users to do shutdown....

Well if you just do what jpbarto said then you can do it right now, easy as, you dont need any additional software or anything. Looks like it would work, jpbarto says it does anyway.
