Configuring GDM login screen

Hi Folks,

I manage a number of RHEL/Fedora workstations at a University. For a very long time I've been able to configure GDM for some simple settings like " disable_user_list true ". For Gnome 2.x I can run commands like this:
/usr/bin/gconftool-2 --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --direct --type bool --set /apps/gdm/simple-greeter/disable_user_list true

Now for GDM in Gnome 3 this seems much more complex. I found this guide:
https://wiki.archlinux.org/index.php/Gnome#Login_screen
but on Fedora 16 & 17alpha it fails when I launch "dconf-service". Despite the "su -" dconf-service still wants to access /run dir of the pre-su user.

Also, I need to setup GDM via kickstart post install or via puppet.. so things like "xhost +" and such aren't really a good choice.

Thanks for any pointers!

Well, I have more info in case anyone cares. None of this is good news.

First, with systemd "su -" is mildly broken. See bugzilla 753882 You can work around this by manually "fixing" the
XDG_RUNTIME_DIR env var.

However, once you get past this and finally set

Code:

gsettings set org.gnome.login-screen disable-user-list true

it still doesn't work. That is covered in bugzilla 708276
