I have already edited /etc/sudoers as described in this topic:
Poweroff or Reboot as normal User
...to allow one specific user to reboot/shutdown via terminal without needing root password, but the user is still prompted for a password when attempting to reboot/shutdown via the menu in the GUI.
What else needs to be edited/modified to allow this?
