[Bug 882255] Re: No administrative actions possible (password refused) after enabling passwordless login
Stragely though, when I reboot my ubuntu and mosue-click some times out of my ubuntu and inside my VmWare player randomly some times, it allowed me in. and also on reboot, it works with an Enter ( i.e removing password effected ). Also i tried to change password with passwd command giving the same string I had used earlier, as new password. Strangely, this fails saying "please enter a longer password". Then why was I allowed to be using a "shorter" password all these days ?

I am affected with Password problem . I have been using a strong passwd. a few days back it began. While log in i have to enter password for a second time. at first time the log in window refuse permission. But when entering the password for a second time , allows log in.

The bug has been disussed at UbuntuForums Ubuntu+1 sub-forum by Precise testers at http://ubuntuforums.org/showthread.php?t=1933237 and confirmed. It's a serious one: Unadvised users may easily get locked out of their systems. In case users get locked out of their system, the description of the workaround to regain access is also presented in that thread. @MIkeBarber: Follow the instructions at the thread I posted above.
