Mechanize alternative that uses kerberos

Hi All, I'm working on an application that needs to crawl a Windows intranet site that does not use NTLM (basic authentication). Does anyone know of a library like mechanize that can use Kerberos? I think Kerberos is the only way this will work but if someone has a different method that would be great. thanks, Leo

After some research I realized I mixed up authentication methods. The server I am trying to access uses NTLM. I'm looking for a way to work with NTLM authentication. It appears that mechanize is using basic authentication.
