You misunderstood me kerberos auth to my corporate http proxy, not to sftp server.
Sftp server uses public key auth

Unfortunately, this applies to HTTP proxy layer as well. We only support Kerberos on Windows. (However, I see that in your code, you actually use NTLM instead of Kerberos, and that might work on Mono in Linux, but not on .NET Core or .NET 5.)
