[system-tools] Problems with authentication when using users-admin

Hi.


I'm building a distro from scratch and have build
gnome-system-tools-2.28.1 with gnome-2.28.1 without problem. When
starting some module like users-admin I'm asked to choose which type
of system my distro is most liked, I've chosen Slackware and them the
configuration screen opens. So far looks fine, the problem is when I
try to make some change clicking in the "Click to make changes" icon
and an authentication popup window quick appear bouncing a message
with a Authentication Failure in the middle:


 System policy prevents modifying the system configuration.



Details
Action: org.freedesktop.systemtoolsbackends.set

Cancel - Authenticate (Pressing authenticate doesn't really work)


I think this problem may be related to some dbus service
configuration, or maybe some gksudo configuration, but really don't
know for sure, I will appreciate any help with this.


Thanks.
