Hi Michal,
I have already enabled TLS for RDP as suggested by this article you linked. That is in fact why I asked my question.
With TSL enabled (as per that article) I am no longer able to connect via rdesktop under Ubuntu. I am not trying to use stunnel on the Windows side to add SSL support to RDP (RDP already has SSL/TLS configured). I am wondering if stunnel on the Linux side might somehow be used in conjunction with rdesktop to allow rdesktop to connect to a Windows-based server configured with SSL.
Or am I misunderstanding the purpose of stunnel?
Best regards,
Daren
