Comment 2 for bug 152107

Can you post your file

/etc/gnome-system-tools/users/profiles

It tells which settings for new desktop users, administrators, or unprivileged user should be used.

Other problem (which need to be patched in users-admin itself) is that when a user is once created one cannot assign a profile to him any more and under the groups on the "User Privileges" tab there is NO "Printer Administration" (for group "lpadmin") nor "System Administration" adds users to "lpadmin".
