I don't know what modifications you are using (I'm familar
with Sandia's work, although I have not looked at the patches in
detail, and I don't know how much of it your site needs.) but you
might want to consider upgrading everything.
MIT hasn't really done much interoperability testing between
recent code and anything before Beta 5. My personal reaosn for not
doing this is the complexity of the pre-Beta 5 build process from the
user point of view. Other developers probably have their own
reasons.
I have looked at sections of the Beta 4 code in order to try
and understand interoperability problems. It's my belief that if Beta
6 is configured properly, it will probably work with an older server.
This belief is supported by several facts. First, I'm fairly
certain I have received bug reports with questions from people using
Beta 6 clients with older servers. The bug reports were small items,
and didn't indicate fundamental incompatabilities. Secondly, people
are successfully using Beta 6 clients with DCE. I believe the DCE KDC
is at least as old as Beta 4--probably older than that.
It's certainly worth giving a try.
