How do I use kerberos authentication with the MIP SDK?

Can I write my own code to obtain a kerberos token and then pass that token in the http auth header for all MIP SOAP calls? I am using script and I have the basic user/SSL scenario working but I have one customer who does not have SSL installed.

We are aware that protocol integration authentication in this context is a pain point for many integrators, and we are hoping to be able to present a better way to achieve this soon, but there is as of this writing no fixed timetable in this regard. I also asked my colleague and he said, to the best of his knowledge, there are implementations of NTLM authentication in Java and Python, but none for Kerberos.
