I was thinking the exact same thing.
I created a new db and a new folder and extracted the source into the new folder. Went through the setup just fine. Under Settings->Users I checked the Registration Required and set the Registration Method to Private. I added the http passthru and ldap plugins and configured them appropriately. Then added a user. When I registered the user from the admin panel, I choose Any Available Backend, set a password, and checked the user cannot change password box. I added another user but the only difference was setting auth to just local.
When I try to login with either user I'm getting the exact same problem. Authentication appears to be good (no red bar saying access denied), the url is tickets.php but the content is the login page.
