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:
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!
