Add the sshagent plugin to forward the ssh-agent protocol over an RDP dynamic virtual channel, just as the normal ssh-agent forwards it over an SSH channel. Add the "/ssh-agent" command line option to enable it. Usage: Run FreeRDP with the ssh-agent plugin enabled: xfreerdp /ssh-agent ... In the remote desktop session run xrdp-ssh-agent and evaluate the output in the shell as for ssh-agent to set the required environment variables (specifically $SSH_AUTH_SOCK): eval "$(xrdp-ssh-agent -s)" This is the same as for the normal ssh-agent. You would typically do this in your Xsession or /etc/xrdp/startwm.sh. Limitations: 1. Error checking and handling could be improved. 2. This is only tested on Linux and will only work on systems where clients talk to the ssh-agent via Unix domain sockets. It won't currently work on Windows but it could be ported.
