[jcifs] NtlmHttpFilter requires username, password and wins server

[Panagiotis Korros]

I upgraded the jcifs.jar from v. 0.7.x to 1.1 and found out that my
configuration was not working anymore.
 
Until 0.7.x specifing the jcifs.smb.client.domain property was enough.
In 1.1 the jcifs.smb.client.username, jcifs.smb.client.password and
jcifs.netbios.wins are also required. 
This causes problems because I don't have a wins server on my network
and also I would like not to expose the username/password in a text
file.
 
If I try without a wins server I get the following NullPointerException
when I try to access a ntlm protected resource.
 
java.lang.NullPointerException: null address || null buffer

...

I hacked the code and saw that NbtAddress.getAllByName( DOMAIN, 0x1C,
null, null ) doesn't work without a wins server but
NbtAddress.getByName( DOMAIN, 0x1C, null, null ) does work. Why is that?
Is it expected?
