Hi again,

I managed to progress. It was related to the security mode being picked. Since 
I didn't specify any, RDP was used instead of NLA, which was enabled in the 
Windows server.

Now, when opening the RDP connection, I see a black window with a mouse pointer 
now. I'm going through various list posts, as I noticed this issue has come up 
several times in the past.


Thanks.

Asunto: RDP connection problems


Hi all,


I'm a bit puzzled trying to get RDP to work, and I hope someone could shed a 
light.


Both FreeRDP and Guacamole server compile correctly.

However, when trying to connect to a Windows server, I see the following 
warning/error message in Guacd:


guacd[72]: INFO: No security mode specified. Defaulting to RDP.
guacd[72]: INFO: Resize method: none

Error: protocol security negotiation failure



FreeRDP version: 1.0.2

Guacamole server version: 0.9.3-incubating

Operating System: Alpine Linux 3.7 (musl-libc)


Compilation options FreeRDP:

cmake -DWITH_XV=OFF -DWITH_XINERAMA=OFF -DWITH_XEXT=OFF -DWITH_FFMPEG=OFF


Compilation options Guacamole Server:

./configure


Although the guacdr.so and guacsnd.so libs are installed, they are not in the 
directories searched. Creating symlinks to the actual location makes the 
warning message disappear, resulting in warning:

Any ideas?


Thanks in advance.
