Bug Description

How to reproduce the bug:
1) Install Ubuntu 11.10 or 12.04 (development branch), and as normal, create a administrator user during the installation.
2) Open Gnome Control Center (also called System Settings), and open User Accounts module.
3) Pick the only existent user (the Administrator user created in the installation), click on Unlock and enter the user password to can do administrative tasks.
4) Click on 'password' to configure password stuff for the current selected user.
5) On 'Action' list box, select 'Log in without a password' and click 'Change' to save the new configuration.
6) Log out (close user session) and Log in again, now you don't need to type the user password to log in.
7) Now try to run some administrative task using sudo or pocicykit to authenticate, they will ask you for your password but they won't accept your old password and neither accept a blank (null) password. This happens also for 'User Accounts' module.

The result is: you cannot do administrative tasks now in Ubuntu.

I think this bug is not exactly the same than bug #907452, because in this case, I am not changging the account type from Administrator to Normal.
This bug is regading the 'logging without password' feature, bug #907452 is regarding 'deleting the unique Administrator' account.
Are you sure they are the same bug?
