I've just created a normal user on my test system and when I try to
reboot or halt the system when logged in via ssh I get:
$ reboot
Failed to set wall message, ignoring: Interactive authentication required.
Failed to reboot system via logind: Interactive authentication required.
Failed to open initctl fifo: Permission denied
Failed to talk to init daemon.
Which is correct behaviour.
However, a user logged in at the machine as GUI console session has
always been able to halt or reboot the system.

If it's a desktop machine, then the console logged in user should be
able to shutdown the machine - at least then it means they don't resort
to pulling the plug. Presumably you don't allow users physically near
a server?
