Josh, you're the man! I haven't gotten to importing my existing users or configuring the community registration process to populate the UBB.t DB yet, but I did bring over a couple sample users and tweaked my login script based on the info you provided above, Josh. Worked like a charm, got the correct cookies in with the correct info and viola, the user is automatically logged in.<br /><br />For anyone also trying to do this, here is what I pulled out of ubbt.inc.php as Josh suggested and added to my login script (and yes, it is PHP) to set the cookies correctly. This chunk goes after the user is authenticated:<br /><br /> srand((double)microtime()*1000000);<br /> $newsessionid = md5(rand(0,32767));<br /> $autolog = md5("$Uid$pass");<br /> setcookie("w3t_myid","$Uid",time()+31536000,"/");<br /> setcookie("w3t_key","$autolog",time()+31536000,"/");<br /> setcookie("w3t_mysess","$newsessionid","0","/");<br /> setcookie("w3t_language","english",time()+31536000,"/");<br /> setcookie("ubbt_pass","",time()-3600,"/");<br /> setcookie("ubbt_dob","",time()-3600,"/");<br /><br />You basically have to make sure the Uid matches up with your existing User ID scheme, and make sure $pass is already an md5 encrypted version of the user's password. You'll notice I had to hardcode some of the cookie variables (such as the language and the path), but nothing too crazy here, and it works great.<br /><br />I'll try to update this as I drop in my existing users and tweak my current registration process to do the DB insert into the UBB.t DB, but it should be relatively easy. The existing users dump should be a simple script looping an insert, and the registration process tweak should also just be a variation of the insert query that Josh pointed me to.<br /><br />Thanks again.
