Comment 27 for bug 445123

For an LTS version (aimed more at corporate environments) this bug issue is ridiculous, especially if the machine is centrally authenticated through AD or NDS. It would result in a list of EVERY valid login for the company being displayed.

Personally I develop SOE's that include a Ubuntu Linux environment and already have a beta build working where I have avoided this issue using gnome (registry) key settings to avoid the problem but that is not an option to everyone, and I would not expect everyone to be able to look into gconf-editor to find the right key to remove it.

Oh and FYI to remove the user list and make it a mandatory setting (so it is always hidden) should be:

sudo -u gdm dbus-launch gconftool --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type boolean --set /apps/gdm/simple-greeter/disable_user_list true
