[ubuntu] Still trying to fix password issue

view story

http://ubuntuforums.org – I changed my password, and was unable to log on. I went into root area, and changed password there. When logging on, it kicks me back to main screen. I used ecryptfs-rewrap-passphrase /home/.ecryptfs/$USER/.ecryptfs/wrapped-passphrase, It asked for old wrapping passphrase, which I assumed was my initial password. It asked for new wrapping passphrase (twice). I got an error: Unwrapping passphrase failed (-5). Info: Check the system log for more inforamtion from libecryptfs. How do I do that? Thanks, (Hardware)
