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.
