Using Keyboard-interactive authentication

[Yizi]

Installed a fresh copy of 14.04 LTS and It won't let me use PUTTY to SSH. I had a look around the SSH config file and made a few changes but still won't let me login. I've followed a few guide but still can't manage to login, example: http://ubuntuforums.org/showthread.php?t=2123275

Thanks in advance.
