Ah, sorry, I didn't know you weren't using GNOME. The gnome-settings- daemon part is not essential at all: the idea was only to use the PID of a process that is known to be running - you can use any program name here.
The polkitd log contains the explanation to your problem: ** (polkitd:1592): DEBUG: subject is in session /org/freedesktop/ConsoleKit/Session2 (local=1 active=0) Your session is not considered as active. Are you working over VNC or another remote desktop system? This is the usual cause of this issue, there's a bug 187585 about that. So the current bug is that users-admin doesn't report correctly when authentication couldn't be obtained. The rest is a problem elsewhere. It shouldn't be hard to fix at all, would you try to write a patch? Else I'll try to do it myself, but I'm not making any promise. ** Changed in: gnome-system-tools (Ubuntu) Importance: Medium => Low ** Changed in: gnome-system-tools (Ubuntu) Status: Incomplete => Triaged ** Summary changed: - users-admin edit dialogs don't show up + users-admin doesn't report error when PolicyKit authentication fails -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/685596 Title: users-admin doesn't report error when PolicyKit authentication fails -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
