You have to enable an undocumented setting in lts.conf for this to work 
(hint: grep SHUTDOWN /opt/ltsp/i386/etc/*).

The reason this feature is undocumented and disabled by default is that
there is NO AUTHENTICATION yet. That means your kids can shutdown/reboot
any terminal they please if they figure this out :-(
