The NTLM HTTP authentication protocol uses some non-standard HTTP
exchanges that require requests be passed without modification over
the same session. If any layer intercepts a message, changes a header,
or closes the session the negotiation can fail. It is known that there
are some environments that have problems and there are clear disclaimers
in the NTLM HTTP documentation about this.
To make it work, I think you would really have to take packet captures
 and output debugging information the the jcifs/http/NtlmHttpFilter
to determine what and where the negotiation is failing.
Greedo shoots first? Not in my Star Wars.
