[Serusers] RPID Handling in ser 0.9.0/0.9.1

Hi all, what's the best way to fetch rpid value from DB in SER release 0.9.0 and 0.9.1? In my test, I've set this 2 modparam line: modparam("auth_db", "avps_column_int", "domn") modparam("auth_db", "avps_column_str", "uuid|rpid") and the function append_rpid_hf("<", ">;party=calling;id-type=subscriber;screen=yes;privacy=off"); is called before t_relay(). But in the release 0.9.0 SER is unable to fetch the rpid value from DB and the call failed when is parsed from my DSS-1 Gateway, wheter in 0.9.1 release all works well. I've, as usual, provisioned the rpid values with 'serctl rpid add' tool. What I'm wrong or missing in my ser.cfg file? Another question....the 2 modparam above seems to be no more mandatory in the 0.9.1....is it ok?? Many thanx Verbal
