I think you'll have to set the ignore certificate setting (guacamole connection option) and
do NLS or TLS auth to 2012 onward

Thanks for that info. I finally got it working, and could successfully conn=
ect with several modules, including RDP.

I now have freerdp 1.1.0 beta1 from 20150312, and my distro is Gentoo.

Connections are OK with Windows Servers 2003 and the default rdp security m=
However, I'm having issues with Windows Server 2012.
I tried using all the security options (rdp, any, tls, nla), but they all f=
ail with the following error:

connected to
recv: Connection reset by peer
Error: protocol security negotiation or connection failure
guacd[8382]: ERROR:=C2=A0=C2=A0=C2=A0=C2=A0 Error connecting to RDP server

I even tried specifying NLA with all the extra settings such as username, p=
assword, domain.

Before I try to disable NLA on this server, I'd like to know if it's a know=
n problem, or if RDP servers above a given version are still unsupported, o=
r if some security modes are known to fail.
