[Twisted-Python] Form based auth - problem with credential checker

I've posted code here: credential checker --> https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-crede... realm.py --> https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-realm... session wrapper --> https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-webau... As I point out on line 14 of realm.py the checker is matching a password against the db but its requestAvatarId (line 10 of *credentialChecker.py * <https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-credentialchecker-py>) is returning None to requestAvatar Any guidance warmly welcomed.
