Are you sure the "ntlm auth = no" is correct? I'm not running a windows domain 
myself, so I can't check but in any case samba should correctly negotiate 
NTLMv2 if the other side requests this. Speaking as someone who has little 
clue about running samba and quite some idea how the samba ntlm code works, 
I'm sure samba tries to do NTLMv2 authentication initially.

Unless someone can offer additional config parameters I have no idea about, I 
guess we would be interested in a network capture of a non-working and a 
working authentication attempt. 

Of course I'm not a samba dev, so those more familiar with all this might have 
a way better solution.
