[SR-Users] auth result -3

Hi all I'm getting an auth challenge result of -3 and I don't know what it means as it's not listed in the auth module doc. Here's syslog' output: db_postgres [km_dbase.c:230]: db_postgres_submit_query(): sending query ok: 0x7f36d1f75f00 (2) - [select secret from sip_buddies where username='48481628780'] db_postgres [km_res.c:108]: db_postgres_get_columns(): 1 columns returned from the query db_postgres [km_res.c:133]: db_postgres_get_columns(): RES_NAMES(0x7f36d1f92238)[0]=[secret] db_postgres [km_res.c:166]: db_postgres_get_columns(): use DB1_STRING result type db_postgres [km_res.c:211]: db_postgres_convert_rows(): no rows returned from the query auth_db [authorize.c:199]: get_ha1(): no result for user '48481628780@' INFO: <script>: Ha fallado la auth con resultado -3 cheers Jon
