Suddenly, I Can't login with correct password (greeter & tty)

Solution 1
Problem solved.
Here are the actions I carried out before the problem got solved:
sudo ppa-purge ppa:gnome3-team/gnome3 (in order to revert back to supported gnome packages like nautilus, ...etc)
creating directory: /var/lib/samba and adding myself to samba passwords databse (sudo mkdir -p /var/lib/samba && sudo smbpasswd -a myusername
sudo pam-auth-update (all the authentication modules were already selected, so I just cliked okay).

Solution 2
I had done chmod 555 to my home folder which created the problem. The solution is to change the permissions back by using someone else's laptop.
ssh (your laptop username)@(your IP)
cd ..
chmod 777 (your username on laptop)

This might be a duplicate of other password related questions but it's somehow eccentric.
I have 3 accounts in my Ubuntu 12.10 system (one standard and two administrators). One of the administrator accounts is my main development account and suddenly before yesterday, it started to act weird (since the latest updates - Kernel and others:
- At the greeter stage, when I enter my password, it instantly returns 'Incorrect password'. It does not even check. (N.B: The password is absolutely correct)
- At TTY, impossible to login, once I enter my login name and then the password, it instantly re-prompts me to enter the login name...It feels like tha path to authenticate this account has been accidently locked or access-sealed.
I logged in with my second admin account and changed the password for the troublesome account, but no luck, reverted the password back to its original value and set the account to auto-login. rebooted and then, indeed the account logged in. Yet, the abonormality remains:
- I cannot perform root privilege actions (sudo & gksudo). Once I enter my password, nothing happens. The only time when the password is accepted is when the screen is locked and that I am prompted to enter the password to unlock it.
I checked the ownership of my home folder and it's ok. Some help is very appreciated.
So to summarize: - Can't login through lightdm - sudo, gksudo & pkexec do not succeed - su command fails - if I provide the sudo command with an incorrect password, it checks and it return "Password incorrect", but if I provide the correct password, it does return nothing. - The password keyring is accepted when I autologin. - The password is accepted when I unlock the screen.
- I already changed the password and checked if my username belongs to groups like (sudo, admin, adm,....).

text about 11 yearsAny problem with the definitions in /etc/login.defs?

Gilles 'SO- stop being evil' about 11 yearsDoes anything appear in the system logs? Particularly/var/log/auth.log, but look at all the files in/var/logthat are modified at the time of your ubsuccessful attempts. Has a file in/etc/pam.dor/etc/pam.confchanged recently? Are the permissions of/etc/passwdand/etc/shadowok? Copy-paste log lines and command output that you need help to interpret. -
Hanynowsky about 11 years@mdpc I don't think so. The file seems okay. It is a common file for all accounts. And as I mentioned, I can login with the two other accounts.

Hanynowsky about 11 years@Gilles this is what I've been doing. Yet nothing weird. I am surprised it only affects one account. I am pasting right away some content from log files in my question. Maybe u could help.
