While PowerShell Remoting (PSRP) over OpenSSH is our plan for the future of PowerShell remoting, we also recognize the difficulty in deploying new servers (e.g. OpenSSH) to existing Windows Server deployments in the enterprise.

Therefore, for macOS/Linux -> Windows remoting scenarios, our goal is to enable existing remoting cmdlets (e.g. Enter-PSSession, New-PSSession, and Invoke-Command) using the traditional WSMan protocol. This currently works for basic authentication as well as for NTLM-based authentication from (only) Linux environments.
