Full Disc Encryption and Root Password Don't Work

[IWantFroyo]

When being prompted for password after installing with full disc encryption, password is invalid. Root and user passwords are invalid as well. Replicatable: I installed twice. Once with full disc encryption, and once without. The first time I couldn't boot up (password invalid error), second time I couldn't log in (same thing). "su" on guest account (which I am using now) also results in invalid password.

I tried multiple times, and I am sure I wasn't typing my password wrong.

Also, when I installed the second time, I wasn't asked for a password to unencrypt the discs, and the installation went successfully. (security issue?)

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
