I interpreted the sentence as meaning "if the user has the correct password, but not username, then tell him so". But on re-reading I can see that it does leave itself open to other interpretations.
A system which says one of "username does not exist" or "password incorrect" (as I believe Livejournal will do) is fine, and in fact is what I'll probably actually implement for the assignment.
