Ok, thanks for the information.
I do wonder if the problem may lay with your password. It's been quite
some time since I used the user-mapping approach, and when I did I'm
fairly sure it was a plain-text pass. Perhaps you could try that?
Otherwise, if you're prepared to try other methods, this is a brief
'howto' I wrote for 20.04 18 months ago. It may need a little updating
with regard to package versions etc, but you could perhaps follow it
through to see if that addresses things for you?
Also, at the end I've commented on your syslog messages...
---- Post from May 2020:
In case anyone's interested here's what I did to get Guacamole 1.1.0
running with Tomcat9 on a fresh Ubuntu 20.04 VM.
Essentially this is the same as my previous list of instructions for
Ubuntu 18.04, however it turns out there is (presently) no libmysql-java
in the repositories for 20.04. Fortunately there is a package for 20.04
on the MySQL site; this requires download and manual install with
appropriate link to /etc/guacamole/lib/.
I've given it a brief try with RDP and it seemed to work fine, albeit
with some odd messages in syslog at disconnect (which I've not pursued)
- YMMV.

track on this forum but how about you try removing (or commenting) the
following lines:

I started by spinning up an entirely new vm running Ubuntu Server
20.04.03 to test with. I used the latest Ubuntu 20.04.03 ISO and after a
quick Google I found the following guide and used it to install
Guacamole 1.3.0. I also ran an apt-get update/install before and after
installing guac and there�s nothing outstanding currently. For right now
I am just using the user-mapping.xml file with a md5 hashed password for
authentication.
Guacamole on Ubuntu 20.04 � Somik's Home
<https://somik.org/guacamole-on-ubuntu-20-04/>
The only thing I added during the Ubuntu install was OpenSSH. Other than
that it was a bare install.
I have since found a few other older guides that mention potential
issues with the freerdp2 package that comes in the official Ubuntu 20.04
repo. I don�t think that�s my particular issue but I�ll probably give it
a try and replace the freerdp2 package with the remmina repository
version and then remake the Guac install.
Failing that I found another guide here: Install and Use Guacamole
Remote Desktop on Ubuntu 20.04 | ComputingForGeeks
<https://computingforgeeks.com/install-and-use-guacamole-on-ubuntu/> so
I�ll try that one next as it is a bit more in-depth.
Regarding rsyslog, what I read said omfile shouldn�t need to be loaded
since it�s built-in. But here is a copy of my rsyslog.conf file:

Vincent,
We'll probably need more information than this to be able to assist you.
For instance:
The version of Guacamole you've installed.
The authentication method you chose (are you using database auth?)
How you installed it (the steps you used, did you use someone's script?)
Also, it looks as if you might want to address the rsyslog issue.
Strange it's coming up from a fresh Ubuntu install, but perhaps try
update/upgrade first. If that doesn't work you may need to look at
rsyslog.conf and compare it against
https://www.rsyslog.com/doc/v8-stable/configuration/modules/omfile.html
<https://www.rsyslog.com/doc/v8-stable/configuration/modules/omfile.html>
Finally, when fault-finding I try to look for common causes to an issue.
In your case it raises a question as to why you're experiencing logging
issues as well as the Guacamole auth problem. You mentioned this was a
fresh install - I wonder what that means? Was this a completely new HDD,
new install of 20.04, or perhaps did you install/upgrade over an
existing version of Ubuntu?
