Here is the issue I can't resolve. Remote RDP server presents a self-signed certificate, and I want to block any connection on client-side when RDP server is using non compliant certificate.
I found a configuration that should enforce server authentication, but it is only blocking when server name in RDP client does not match server certificate CN (for exemple, if i try to connect using IP instead of host).
I can't find any local configuration (GPO, local strategy...) to block RDP connection when server is using a self-signed certificate.
(I am not looking for configuring a compliant certificate on server side, because anyway, my client is configured to accept any certificate that has the server name is the certifcate CN field).
