Comment 28 for bug 431147

Me too. Nothing happens when klicking the Unlock button.

Behaviour:

When gdmsetup is started from the System>Administration menu, locally, the button becomes gray when pressed and resumes normal appearance when released.
When "gdmsetup" is started from a terminal with ssh X11 forwarding, the button becomes gray when pressed and resumes normal appearance when released.
When started with "sudo gdmsetup" and "gksu gdmsetup" from a terminal with ssh X11 forwarding, the button becomes gray when pressed and stays gray/inactive when released.

User-admin behaviour, for reference:

When "users-admin" is started from a terminal with ssh X11 forwarding, the unlock button is already gray and a text (in swedish that translates to) "Not authorized to make changes".
When users-admin is started with "sudo users-admin" there is no unlock button, and operations are allowed.

Ubuntu 9.10 was installed from scratch but /home was copied from a 9.04 system.

No process "polkit-gnome-authentication-agent-1" is running.

Kernel: 2.6.31-17-generic
