[Serusers] Credentials problem for calling out

Hi, I have installed SER on a machine and I have mysql DataBase elsewhere. I was able to add new users to that DB using serctl and even chenge their group to ld. All the new users created are able to register but when I check whether they are in ld and can call out in ser.cfg it always tells that they have no permission and not in ld. I think it is checking localhost DB for credentials to call out but I am sure for registration it is checking DB on other machine. I included there in my ser.cfg modparam("usrloc", "db_url", "mysql://user:secret@othermachineip/ser") modparam("auth_db", "db_url", "mysql://user:secret@othermachineip/ser") modparam("acc", "db_url", "mysql://user:secret@othermachineip/ser") Please tell me what more should I include for making it point to DB on other machine even for checking credentials for calling out. Thanks, Manoj.
