Apache Guacamole - How to enable totp?

[EcN000]

Glad to see guacamole added, but it seems that it's missing the option to enable totp or duo. I was previously able to enable it in the docker config, but not sure how to enable totp in this case. thank you.

I am a complete novice, but this is what I did to get TOTP to work with guacamole.

I logged in to the LXC console and downloaded the TOTP extension
wget https://dlcdn.apache.org/guacamole/1.5.5/binary/guacamole-auth-totp-1.5.5.tar.gz

Extracted the tar file
tar -xvf guacamole-auth-totp-1.5.5.tar.gz

Moved the TOTP jar extension to the correct directory
mv guacamole-auth-totp-1.5.5/guacamole-auth-totp-1.5.5.jar /etc/guacamole/extensions/

Removed the downloaded tar.gz and the extracted files/folders that were not used
rm guacamole-auth-totp-1.5.5.tar.gz
rm -r guacamole-auth-totp-1.5.5/

Rebooted the lxc and boom! Everything seems to work.

The other thing I did was to have https://myip:8080 redirect to https://myip:8080/guacamole/ instead of viewing the tomcat page.

First i saved the original index.jsp as oldindexjsp
cp /opt/apache-guacamole/tomcat9/webapps/ROOT/index.jsp /opt/apache-guacamole/tomcat9/webapps/ROOT/oldindexjsp

Replaced the contents of index.jsp with the redirect to /guacamole
echo "<% response.sendRedirect("/guacamole");%>" > /opt/apache-guacamole/tomcat9/webapps/ROOT/index.jsp

Again I am a complete novice, if there is anything that is not the correct method to install TOTP or in the tomcat redirect please let me know. I hope this helps.
