If that person is trying to log in with root from one of the latest image, they're going to get an error, which is possibly a PAM error. Robert changed the root account so one can not by default log in over ssh as root. It can be fixed, but it's probably nto a good idea for anyone to "fix" this. Instead keep security in mind when logging into their board.
