Comment 14 for bug 882255

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.
I am using a laptop and my key board marking are not visible , is using a key board through usb.
Today I was totally refused login while booting. So I rebooted system and change my password through recovery , and when came back for login to desktop, the new password which was by -heart to me was rejected. So i have to went back repeat pwd change process. Then used the new pwd to log in . the next thing i did was to log into users and group session and taken option for to log in with out a password. when rebooted and attempted login , the log in window appeared and refused entry without password. When i gave my password , allowed log in.
A window option for kerying also is asking similar repeated incident for password even the correct password is entered. After a few repetition with the same pass word , it allows acceptance of the same password. something wicked is playing.
