The shutdown(8) binary ("/sbin/shutdown") is not owned by the
"wheel" group (do an "ls -l" on it), but by the "operator"

I personally set the execute bit on "/sbin/shutdown" for
others on my desktop machine, as I want anyone using it
(locally, no remote access enabled) to be able to shut it down.

To do this: "chmod o+x /sbin/shutdown". Might be a good idea to
understand the setuid concept beforehand, if you don't
