Didn't see the archived discussion, but this method works for me:

Create executable /usr/local/sbin/shutdown which does a sudo shutdown:

    #!/bin/bash
    sudo /sbin/shutdown $*

Add users to /etc/sudoers with permission to run /sbin/shutdown.  Eg add line:

    user    ALL = NOPASSWD: /sbin/shutdown

Edit /etc/gdm.conf and change the RebootCommand/HaltCommand to use
/usr/local/sbin/shutdown.

Run gdmsetup as root and configure gdm to show the system menu.
