Yeah, that definitely sounds like a problem with Websphere on Linux. The
NTLMSSP exchange is pretty strange so unless the web server is considerate
of it it's very possible for things to get messed up. I would create a
bug report with at the WebSpere side.

Just for kicks you could try dopping in the latest jcifs
jar. We have tweeked how the http connection is handled over time
(e.g. setContentLength(0) after setting status just changed in the
last release).
