Comment 1 for bug 219473

I've seen this problem when I install Xvnc (vnc4server) and attach to the host. Local display (via terminal screen) allows me to unlock users & groups, or 'system services'. When I vnc I cannot unlock as the button is greyed out. This is a pain and doesn't exist in Ubuntu, only my first installation of Xubuntu 8.04. Again, like original description my system is not accessible via a local terminal.

Another minor gripe which may or may not be related is the screensaver never kicks in Xubuntu compared to Ubuntu where it kicks in after a timeout and locks the screen. I dont know if this is related to this 'admin' thin-client issue or there is another bug raised?
