I'm also struggling with getting this going. We're using UltraVNC as well, and have enabled MS Logon.
I built guacamole-client and guacamole-server from source (pulled this morning from GitHub) on Ubuntu 18.04, and when I try to connect, the web client gives the message: The remote desktop server is currently unreachable. If the problem persists, please notify your system administrator, or check your system logs. Looking at journalctl, the logs from guacd are: Jan 30 21:47:13 mars-ubuntu guacd[1720]: Creating new client for protocol "vnc" Jan 30 21:47:13 mars-ubuntu guacd[1720]: Connection ID is "$6d308e74-dc49-48d3-b331-a0869b31d31f" Jan 30 21:47:13 mars-ubuntu guacd[9233]: Processing instruction: size Jan 30 21:47:13 mars-ubuntu guacd[9233]: Processing instruction: audio Jan 30 21:47:13 mars-ubuntu guacd[9233]: Processing instruction: video Jan 30 21:47:13 mars-ubuntu guacd[9233]: Processing instruction: image Jan 30 21:47:13 mars-ubuntu guacd[9233]: Processing instruction: timezone Jan 30 21:47:13 mars-ubuntu guacd[9233]: Cursor rendering: local Jan 30 21:47:13 mars-ubuntu guacd[9233]: Parameter "swap-red-blue" omitted.

I'm able to connect to other computers that are running x11vnc, but am struggling to get it working with UltraVNC (which some of our computers need to use). At first, I thought it was related to https://issues.apache.org/jira/browse/GUACAMOLE-414 because, when building on CentOS 7, I was getting a warning while compiling guacamole-server: This version of libvncclient lacks support for TLS locking. VNC connections that use TLS may experience instability as documented in GUACAMOLE-414 Since I had issues with upgrading libvncclient on CentOS, I tried Ubuntu 18.04, and I don't get that message anymore, but I still cannot get UltraVNC connections to work when using MS Logon. Vieri-2, any insight you can provide on your build environment or configurations you've set in UltraVNC to make this work? For what it's worth, I've manually specified the username and password in the Guacamole web interface for VNC, not in LDAP using guacConfigParameter (I can't modify the LDAP schema). -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/ --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@guacamole.apache.org For additional commands, e-mail: user-h...@guacamole.apache.org
