Comment 24 for bug 240437

Xubuntu 9.10 (Karmic Koala) Alpha 5 (02-Sep-2009) Live CD

Starting from GUI:

Menu Users and Groups:
Users Settings box shows no users.
Select "Click to make changes" button, then enter "" (null) password.
Manage Groups box is also blank.

cat /etc/passwd shows expected full list of users (30)
cat /etc/group shows expected full list of groups (58)

Using GUI, add user "test" with UID of 1000 and administrator profile.
Error message: "The configuration could not be saved - an unknown error occurred."
Error message: "System policy prevents modifying the system configuration" and requests a password for root. Try Passwords "" (null), "ubuntu" and "root" but none accepted!
Note that this error identified as from org.freedesktop.systemtoolsbackends.set

No entry appears in Users Settings box.
However, home directory for "test" is created.

cat /etc/passwd now shows only eight users, including the new user "test":
(root, daemon, syslog, messagebus, avahi, haldaemon, ubuntu, test)

cat /etc/group now shows only nine groups:
(root, daemon, audio, nogroup, syslog, messagebus, avahi, haldaemon, ubuntu)

sudo capability now lost.

============================
Starting from terminal:

Result are very similar to starting from the GUI with the addition of this terminal output...

============================
Conclusion:

Fault basically unchanged from that first reported.

Should be re-opened.
