Comment 22 for bug 183673

Just ran into this bug. Clean installation of Ubuntu Desktop 8.04.

Running "users-admin" from console works as expected.
Running "users-admin" or "sudo users-admin" from remote connection (e.g. ssh X11 forwarding, NXClient, etc) does not allow administrative access to unlock the tool.

The error given is:
** (users-admin:9673): CRITICAL **: Unable to lookup session information for process '9673'

"ck-list-sessions" output below shows minor differences between a local and remote session.

Session1:
 uid = '1000'
 realname = 'Gilbert Mendoza,,,'
 seat = 'Seat1'
 session-type = ''
 active = TRUE
 x11-display = ':0'
 x11-display-device = '/dev/tty7'
 display-device = ''
 remote-host-name = ''
 is-local = TRUE
 on-since = '2008-05-29T16:48:47Z'
 idle-since-hint = '2008-05-29T17:09:07Z'
Session3:
 uid = '1000'
 realname = 'Gilbert Mendoza,,,'
 seat = 'Seat3'
 session-type = ''
 active = TRUE
 x11-display = 'localhost:10.0'
 x11-display-device = ''
 display-device = '/dev/pts/0'
 remote-host-name = 'hostnamewashere.local'
 is-local = FALSE
 on-since = '2008-05-29T21:10:32Z'
