[jcifs] new exception thrown in version 1.3.16

[bryan.coleman at dart.biz]

One other thing of note: The share with the issue lives on a Fedora 15 box 
running samba version 3.5.8 with security=server and password server = 
<MICROSOFT DOMAIN CONTROLLERS>.

I tried a slightly modified version of ListFiles.java (removed for loop 
and replaced "file = SmbFile(args[a]);" with "file = 
SmbFile("smb://server/directory/", new 
NtlmPasswordAuthentication(<domain>, <username>, <password>));".

It runs just fine with lmCompatibility=0 and fails without it.

Here is the output upon failure:

P. S. The mailing list URL is still broken.  I get a "Not Found: The 
requested URL /listinfo/jcifs was not found on this server."

That actually doesn't make sense because I don't think you can do
NTLMv1 without extended security.

Try the examples/ListFiles.java example from the commandline without
setting any properties. If that does not work, post the full command
used and the full stack trace.
