Hi Nick, thanks for following up. I just did a quick test of a nightly build (2.0.0-dev5 (245fc6014)) of wfreerdp and it supports preconnection blobs – doesn´t look like support was removed in general. Thus I´d assume it is more like guacamole does not recognize it, or the build options used by Debian do not support it.

I am using guacamole mostly to connect to Hyper-V virtual machines, using the preconnection blob mechanism. Now when I connected to the new guacamole, I was able to authenticate using my extension (thanks for staying compatible!), but connections failed. In guacd log I found the cause: guacd[100]: WARNING: Installed version of FreeRDP lacks support for the preconnection PDU. The specified preconnection BLOB and/or ID will be ignored. Is there a reason not to compile with Hyper-V support out of the box? Did I miss a discussion on the mailing list? Or is it by accident Debian has the wrong default? It seems like FreeRDP 2 either removed support for this or has changed it to the point where Guacamole doesn't recognize it. Worth some additional investigation - if they've just changed it and we need to adjust, then it's worth a JIRA issue on our side. If FreeRDP 2 has removed it then there isn't much we can do about it. It looks like FreeRDP 2 supports it, so there's something in the Guacamole code that sets/detects it that has broken with the switch to FreeRDP 2. I've opened a JIRA issue for it: https://issues.apache.org/jira/browse/GUACAMOLE-952 -Nick
