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.
