make a copy of shutdown to some other directory (keep it named shutdown
because it looks at it's name to determine it's behavior).
addgroup buddies # edit /etc/groups and add your two users to it
chown root.buddies shutdown
chmod 550 shutdown
chmod +s shutdown
Now only root and your two users can execute this binary.
