Ok, taking a different tack on this. Rather than running it as a 
separate server process, run it as a WSGI app inside Apache. This 
required a fair bit of re-tooling and complicates the set up a little 
bit. I think I've got it all covered in the man page.

On the python-kerberos front I've got bugs opened in Ubuntu and Debian 
to see if we can get the patch accepted their until (if) upstream ever 
takes a look.
