I think that we are going to need to see what is happening at the protocol 
level to figure this out. 

Can you grab a tcpdump capture or something like that of the packet 
activity that occurs, and send it to us along with what an outline of what 
you think each process should be doing.

In answer to your question, there should be no significant differences 
between the libsmbclient code in 2.2.7a, 2.2.8a and 3.0.0, especially with 
respect to what you are doing.
