Hi, I currently have custom php based system which keeps whole users database in mysql. I'm trying to make otrs use the same database (read-only) but the problem is that users are not keept in one table... there are multiple tables which contain information about users. From what I see otrs wants one table with all fields in it (at least that's how it looks on example http://doc.otrs.org/1.2/en/html/customer-user-backend.html) Is it possible to define my own SQL queries or better force otrs to get all data from some page like http://xyz.pl/users.php (so I could write all SQL magic into users.php and return proper entries). http-link in CustomerUser is for this purpose or something else?
