Re: system shutdown from xdm
You could also use sudo to let certain people have the privilege of
running shutdown. They won't need to know the root password, only their
own, and you could even set it up so they don't need their own password.
Here's an example sudoers entry:
<username> <machinename>= /sbin/shutdown -[hr] now
would allow the user _username_ to run either the shutdown or reboot command
on the host _machinename_. A simple modification to that would allow
_username_ to run the command without her own password. See man 8 sudo, man
5 sudoers and man 8 visudo.
