The "N" in the documentation means some Number and not a literal "N".

I don't think 1.3 supports plain text passwords. 1.2 might but I have
not tried plain text passwords in a LONG time.

What's the exception? Is it "unknown user name or bad password"? That is odd.
Does it help if you use "smb://fileserver.xxx.nl/My%20Test/" instead?

This setting could be a problem. JCIFS 1.3 uses NTLMv2 by default. Set
jcifs.lmCompatibility = 0 and jcifs.smb.client.useExtendedSecurity =
false so that NTLMv1 is used. Does that fix it?

Wow, those are some serious Samba configuration options. Do you really
know what all of those things do?
