Did anybody test smbclient4 against smbd4 using SMB2

[Jun Yi]

Hi Andrew,

I forgot to attach the log at the client side, please find it in the
attachment.
I also add some debug by myself, please see the following debug output in
the client log:
----------------------------------------------
SMB2 dialect revision received from server is 767
The common SMB2 dialect revision for both client and server is 0
SMB2 dialect revision received from server is 528
The common SMB2 dialect revision for both client and server is 7
NEG SUCCEEDs
----------------------------------------------

Does the debug output above proved that the negotiation phase is not the
problem? I observed that the client silently closed the TCP connection
after two rounds of protocol negotiation.
Will the problem be the authentication method negotiation? Please point it
out to me.

Thanks and wait for your reply!

Jun
