Hello, I was reading about secure Dialect negotiation to prevent man-in-middle to downgrade dialects & capabilities. _https://blogs.msdn.microsoft.com/openspecification/2012/06/28/smb3-secure-dialect-negotiation/_ I wanted to ask, is there any option to disable SMB2 to do dialect renegotiation as present in Windows8 clients, as they can control using RequireSecureNegotiate. -- Thanks Amit

I noticed there was Bug 12808 against 4.6.3 ( if I read it right ) about smblcient doesn't handle STATUS_NOT_SUPPORTED gracefully for FSCTL_VALIDATE_NEGOTIATE_INFO. We are currently updating to 4.6.6 and I do not see it in smbXcli_base.c. I see the fix was done in 5/30/2017. Is this something that is still needed, and will be added in future releases ? I would like to know whether I should update 4.6.6 or not. Regards, Mike Tompkins
