The Kerberos package *has* domain based DFS support. But I seriously
doubt the success of the Kerberos package has anything to do with
Kerberos. The Kerberos package requires special usage to actually get
it to do Kerberos. Meaning you would get precisely the same result
with the equivalent non-Kerberos version of JCIFS.
Your analysis of the problem isn't optimal. Test a standard JCIFS
example with a standard JVM with a standard server so that you see it
work. Then change one thing at a time systematically until it breaks.
Just saying "that fails too" is going to get you nowhere. You need to
provide error messages, thread dumps, log fragments, captures or
whatever you can get that shows what is happing at the failure
