ok, so everything works for me with one exception: If user is already in osTicket database, then auto login works (user don't need to provide login or password). The problem is when new user in AD want to login to osTicket first time, it's fail... When I had 1.9 version, osTicket created for me new user account in database in a fly (user wasn't aware of this) and now in new version, new AD user must to go to login page and login once and then he is available to login automatically, so I probably mess up something or need to change something in login.php ?I will edid mentioned changes in ajax file tomorrow.
