[Users] aut_db module and realm

Hello to everybody, I configured the openser.cfg as follow: #----------------------------------- # AUT_DB parameters #---------------------------------- modparam("auth_db", "db_url", "mysql://openser:openser@localhost/openser") modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "domain_column", "domain") modparam("auth_db", "user_column", "phone") modparam("auth_db", "password_column", "password") In this way openser checks for authentication the phone number instead of the username (it works fine!!). My problem is realted to domain. Entering the modparam(.....,"domain") I was expecting to see the domain column populated in the table location, but it doesn't happen. Do I have to configure something else? Moreover, anybody could explain me the meaning of the column location.received? thanks in advance Alessandro
