I installed UBUNTU using encrypted LVM .. like in the link below:
http://www.linuxbsdos.com/2011/05/10/how-to-install-ubuntu-11-04-on-an-encrypted-lvm-file-system/
When I boot it prompts me for a pass phrase to decrypt , and it was working fine till I changed the user login password.
After changing the user login password I rebooted and now my de-crypt passphrase is not working (Ques: Is changing user login password can really be a reason ?)
Any inputs on how can I recover the password (decrypt passphrase), as the de-crypt pass phrase will not even let me login into the recover console.
