[Samba] SMB 311 Negotiates and then stops

[Tompkins, Michael]

Re-sending ... We tend to see a lot of issues with NetApp servers and SMB 311. Not sure what might be wrong with their response packet, that 4.6.6 doesn't like.

We are running Samba-4.6.6 and are running into an issue where it negotiates to a NetApp server but then the client stops the connection.

This is at a customer site, and we cannot recreate it here due to lack of server. Attached is the wireshark trace. Not sure what the client doesn’t like.
