I agree that it was probably two separate issues.

As I explained in Message #44, my problem appeared to be NetApp 
specific. The administrator of the NetApp server to which I was trying 
to connect told me it was running ONTAP 9, which supports SMB 3.1.0 but 
not SMB 3.1.1. Assuming he was right, this explained most of my problem, 
except why smbclient was unable to negotiate the use of a mutually 
supported protocol.

It did look like Samba bug 13009, but I was definitely running 4.7.3. I 
guess the problem was out-of-date software on the NetApp server.
