[SR-Users] Kamailio Failed to Query the Asterisk DB to Authenticate Registration Requests.

Hi Dears, I'm trying to configure Kamailio as SBC in multi home mode for Asterisk by authenticating the inbound SIP registration requests,i'm following this tutorial http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb to achieve this goal. i have modified the necessary changes like the Asterisk DB URL and the SIP table name and Username and password column and verified the Mysql connection. My topology like this Asterisk (192.168.100.10) <----Internal:192.168.100.1---->Kamailio<---External:192.168.50.1-----> SIP Phone (192.168.50.2) But when trying to register a SIP phone Kamailio generates these error messages Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Unknown column 'secret' in 'field list' Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: auth_db [authorize.c:175]: get_ha1(): failed to query database The Auth_DB Params in the configuration file is as follows. # ----- auth_db params ----- #!ifdef WITH_AUTH modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "load_credentials", "") #!ifdef WITH_ASTERISK modparam("auth_db", "user_column", "account") modparam("auth_db", "password_column", "secret") modparam("auth_db", "db_url", DBASTURL) modparam("auth_db", "version_table", 0) #!else modparam("auth_db", "db_url", DBURL) modparam("auth_db", "password_column", "password") modparam("auth_db", "use_domain", MULTIDOMAIN) #!endif I tried also to give the Auth_DB module all the paramaters like this but still receiving the same error ! So any ideas about the cause of the problem and how to solve it please ? # ----- auth_db params ----- #!ifdef WITH_AUTH modparam("auth_db", "user_column", "account") modparam("auth_db", "password_column", "secret") modparam("auth_db", "db_url", "mysql:// sipuser:sippassword@192.168.100.10/asterisk") modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "load_credentials", "") #!ifdef WITH_ASTERISK modparam("auth_db", "user_column", "account") modparam("auth_db", "password_column", "secret") modparam("auth_db", "db_url", "mysql:// sipuser:sippassword@192.168.100.10/asterisk") modparam("auth_db", "version_table", 0) #!else modparam("auth_db", "db_url", "db_url","mysql:// sipuser:sippassword@192.168.100.10/asterisk") modparam("auth_db", "password_column", "secret") modparam("auth_db", "user_column", "account") modparam("auth_db", "use_domain", MULTIDOMAIN) #!endif
