The server is a win10.
The login fails (bad user/pass) when using the win10 rdp client.
The login succeeds when using rdesktop from WSL ubuntu.
Could it be that the win10 rdp client isn't compatible with the win10 rdp server, which only a linux rdp client is compatible with? 🙄
Maybe I should mention that I'm using an ssh tunnel. Maybe rdp connecting to localhost confuses it in terms of credentials? It shouldn't.
I leave it as another win10 bug. RDP isn't so good anyway, and it has vulnerability (although, I don't intend to use it to access my computer):
NoMachine is better anyway.
But I'm still curios about this.
