ACS, MAB users authentication with MYSQL DB

[ciscoexarmic]

Hi ALL!!!

I want to authenticate mab users which are my ip phones with mysql database.My mysql database was filled with mac adddress by means of mac notification feature. Havig read the User guide for ACS i created procedure in mysql that was applied  and configure acs to check external ODBC database ( unknown user policy). I have configured ACS  on "ODBC configuration" page to use mysql's procedure for mab users authentication. But ACS don't query mysql to authenticate user. I found out it  when i decided to sniff packets with wireshark.

Can anybody help me ? why ACS don't query mysql?

I went on my search after i had posted this discussion. I think it is impossible to use external odbc database in order to validate mab users credentials. The only way is to use LDAP for mab users authentication!
