Comment 14 for bug 219473

I just wanted to add that this affects remote X-logins as well. When I am logged in through GDM from a different computer the unlock button in the users administration GUI is also grayed out.

Here are some data:

Ubuntu Hardy Heron
--installed from server 64
--apt installed ubuntu-desktop

root@donald:~#ck-list-sessions
-----cut------
Session10:
 uid = '1000'
 realname = 'Holden Hao,,,'
 seat = 'Seat8'
 session-type = ''
 active = FALSE
 x11-display = '192.168.1.111:1'
 x11-display-device = ''
 display-device = ''
 remote-host-name = '192.168.1.111'
 is-local = FALSE
 on-since = '2008-07-05T04:06:38Z'
------cut end-----

Other note:
Access to local devices on the server such as a scanner exhibit similar behavior. Users can use the scanner if directly logged in to the server. However, from their remote x-sessions, Xsane can not detect the scanner. This is true even if implicit policy kit access to the scanner is already anyone "yes", console "yes", and active console "yes". I will post the same info in another bug report.
