I just tried Hardy, and this behaves as expected for me. The Unlock button should always be greyed out in users-admin by default when running over a SSH session, as the default Ubuntu policy for this action is to only grant authorization when running on the active console. A SSH session can never be on the active console.
The Unlock button in users-admin is active for me over VNC when the users session on the local machine is on the active console. If the users session is on an inactive console, PolicyKit will not grant any authorization, as this is the default Ubuntu policy (which you can adjust BTW). The empty output of "polkit-auth --show-obtainable" is what I would expect to see if the session that is called from is not on the active console, unless you have altered the Policykit settings on your machine. For those of you experiencing a problem, please provide the output of the following commands (obtained from within your VNC session only): "ck-list-sessions" "polkit-auth --show-obtainable" "dbus-send --system --dest=org.freedesktop.ConsoleKit --type=method_call --print-reply /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.GetCurrentSession" Thanks in advance -- policykit not available over Vnc sessions https://bugs.launchpad.net/bugs/238799 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
