SASLDB not working

i have finally gotten amavis, clamav, set-up as described in afp548.com. my new problem is that i can no longer use sasl for login purposes. i am using md5 challenge response. i can send mail via the server, email are being processed coming in but i can not log in and check the mail. i hoping that someone has some insight on this. i know i haven't provided my info. i will login later and provide some logs.
