[jira] [Commented] (GUACAMOLE-1367) Fail to etablish RDP connection

["Adam Scheblein (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GUACAMOLE-1367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17370924#comment-17370924 ] 

Adam Scheblein commented on GUACAMOLE-1367:
-------------------------------------------

I'm going to add this to save others some time.

This is a workaround for connectivity issues with RDP: [https://github.com/MysticRyuujin/guac-install#note-debian-users-having-issues-with-rdp-have-reported-the-following-fix]

I discovered this many many months ago, and just rediscovered it this afternoon. I found it by way of the Bitnami forums: [https://community.bitnami.com/t/ova-version-1-3-0-3-rdp-problem-guacd-1-3-0/91414/21]

> No obvious errors in the logs :(
> In the interface, I have a black screen and the connection is immediately opened !
> I had tried (without restarting the server because it is currently in production) to disable in the RDP settings of the server the option "NLA authentication" but it does not change anything :(
> My Guacamole server is installed on a Debian 9.13. I installed directly from the tar.gz retrieved from Sourceforge.net (https://sourceforge.net/projects/guacamole/files/current/source/guacamole-client-0.9.14.tar.gz/download)
> Many thanks
