David, My only guess is that the logon request (POST /iddb3/iddb3_2/login.verify) fails due to invalid credentials or some other reason. I see no session cookie in the response. The UserId and pUserId cookies are too simple and may not necessarily be session cookies.
Anyways, knowing what exactly what handshake the site expects is your best chance. Take a look at the Ethereal http://www.ethereal.com/download.html See if you succeed in capturing the HTTP traffic between the browser and the site using this tool.
