User Database integration

[*****Sniper]

I dont have to integrate the software, I just have to be able to allow the users in another database to access VB3. This is because there are over 2M users in the Database and cannot be migrated over to the VB3 database.

What I think I have to do is edit the login page so it takes the userid, username & password from the other database. Following is the SQL that does so.

$sql = "SELECT id, username, password FROM anagrafica WHERE username='".addslashes(htmlspecialchars_uni($usern ame))."'";
Also that DB is Oracle, not mysql.

problems: Password is plain text, not md5 encrypted. No "salt" field. different identifying names (eg. $bbuserinfo['id'] and not $bbuserinfo['userid'])
can anybody point me in the right direction?

I've started looking at the login.php file but am not sure what to modify?!?!
