How do I auto-login a user with web client 4.5.3? Error: 0x80040405

System

I would like to have my clients automatically login to the mediabin 4.5.3 web client without having to enter the credentials. My mbin web client, sql server, and mbin application server are on three seperate servers and all members of the same domain.

I have the web server configured to disallow anonymous access, enabled Windows authentication, and tried to digest and not digest Active Directory.

I have modified the global.asa in the following manner:
' Turn on Integrated Windows Login?
Application("ENABLE_INTEGRATED_LOGIN") = "True"
Application("INTEGRATED_LOGIN_SERVER") = "TKXTMEDIABIN.Partners.Extranet.Microsoft.com"

This is the error that I get.
Unable to connect to server. Reason: The requested object does not exist. (0x80040405)

Integrated login (auto-login) is only supported by Internet Explorer. You may be able to find third party support for FireFox, but Interwoven does not officially support that browser for 4.5.3.
Credentials must be passed from the browser to the web server and from there to MediaBin server. NTLM does not permit passing credentials across multiple servers. Therefore, you must have Kerberos authentication enabled. To use NTLM, MediaBin server and IIS must coexist on the same server.
Please contact Interwoven Support for more information on configuring Active Directory and IIS for Kerberos integrated login. Interwoven Support should be able to provide you with a document that contains guidelines for configuring Active Directory and IIS. You will very likely need to work closely with your IT department to get this working. We have multiple customers that are using it, so it has been proven to work, but has been known to be quite complicated to get working at some sites.
