First question, how did you reset the password for a user account if you don't know the name of said user account?
Nevertheless, when you are in the password-less root shell where you used the passwd command, I'm assuming you have full command access. Can you not just navigate to your home directory, 'cd /home/' and then see what users have home directories via 'ls'? Just a thought.
