I suspect that user just never visited the bbPress portion of your site.

There are four ways a user will get their role set in bbPress once the role map is setup:

1. If they register through bbPress (will also give them a role in WordPress)
2. If they register through WordPress, then visit bbPress whilst logged in
3. If they register through WordPress, then logout, then log back in through bbPress at some stage
4. If they register through WordPress, then an admin re-saves the role mapping in bbPress
