"Normal" (unpriveledged) users can shutdown/halt or shutdown/reboot a
vanilla Slackware Linux box with no problem.

a) From any (character) console: <ctl><alt><del> will shutdown/reboot
(see the "ca" line in /etc/inittab)
(FWIW, <ctl><alt><Fx> will move you from a GUI to a console, where
you can then <ctl><alt><del> to shutdown)

b) From any login, a login as user "shutdown" will cause the system to
shutdown/halt (see /etc/passwd user "shutdown", which runs
/sbin/shutdown as it's shell)

c) From any login, a login as user "halt" will cause the system to halt
(see /etc/passwd user "halt", which runs /sbin/halt as it shell)

d) From KDM (KDE's XDM replacement), the user is permitted to select
either the "reboot" or "halt" shutdown option.

e) From GDM (Gnome's XDM replacement), the user is permitted to select
either the "reboot" or "halt" shutdown option.
