JSF 2 - form based Authentication without JDBC

Hi, I need a little help with JSF2 application which is run on Glassfish 3 and user authentication .

I want to use Form-Based Authentication with Container-managed security. I've got few tutorials but everyone is based on direct connect to database to verify user and password. (like this one: http://blog.eisele.net/2011/01/jdbc-security-realm-and-form-based.html[^])

In Container-managed security I've to configure my Glassfish Realms. Set user table, user name column, password column... even group table in my database. Then just use: j_username, j_password.

And my problem is: I don't want to direct access to the database. My application will use many database. And not always table with users will be named the same. So I have web-services, that get username,password and database name as parameters and return information whether the password is ok or not.

I want to use similar solution but without JDBC, and every access to the database will be via web-services. Is that possible to do that without specifying database tables and columns with users at the beginning and use for example web-services instead?

Thanks for help,
Regards,
