[jcifs] NullPointerException

[jbaker-jcifs at javasystemsolutions.com]

Hello all,

I posted this a few weeks ago but didn't seem to get any response, but I also 
didn't see the mail in the list archives so perhaps it was not delivered. 
Therefore, apologies if this has already been posted.

I am getting a NullPointerException from jcifs when trying to authenticate 
against the following:

- Windows 2000 functional AD domain running on Windows 2003
server.  
- The web server is IIS 6 and New Atlanta ServletExec version 5 installed.
- Using the ntlm filter provided with the jcifs package.

And here is the stack trace:

I've Googled this NPE and have found a few posts dating back to 2003, so I'd 
assume this problem was fixed now. However, it would appear a problem still 
exists.

Does anyone have any idea what's going on? Would you like me to get more 
information in order to diagnose the problem?
