I think you need to delete them (remove the characters between the first and second colon) because they get stored in an encrypted method. You'd have to know what wacky string to type so that the encrypted output matches whatever plain text is in there... I think go back in through system rescue cd, delete the passwords, log in with blank passwords and then change them using passwd. > > After a reboot the original passwords, the new passwords, and the > passwords reset using the System Rescue CD all failed. > > Note: I had one existing non-root user whose password I did not > modify.
