$HOME for guacamole-guacd is set as /home/guacamole-guacd after installing this app, and since that dir doesn't exist, this failure always happens for RDP connections.

After some digging and a chat with the freerdp devs, it seems the way that guacamole is using freerdp is tied to this requirement. See: https://issues.apache.org/jira/browse/GUACAMOLE-931

Context

Steps to reproduce

  1. Install guacamole
  2. Access guacamole's interface
  3. Set up a new RDP connection
  4. Attempt to use new connection

Workaround

Create /home/guacamole-guacd and set ownership to guacamole-guacd:guacamole-guacd
