Some introduction: When I started this project Guacamole 1.4.0 was still the
latest version so I'm still using that to develop my extension. Once I have it
working properly I want to test it with Guacamole 1.5.1. Also, the company I
work for is branding Guacamole as "Clientless RDP" or CRDP so you'll see that
name at several places.
I have the following files in place:
- guacamole-1.4.0.war file saved as /var/lib/tomcat9/webapps/clientlessrdp.war
- auth-jdbc extension saved as
/etc/guacamole/extensions/guacamole-auth-jdbc-mysql-ndaw-1.4.0.jar
- my branding extension saved as /etc/guacamole/extensions/ndaw-crdp-1.4.0.jar
When I start Tomcat the logs show:

So that seems fine. There are no other errors being logged. The missing logo is
only shown in the access logs:
[04/May/2023:09:20:23 +0000] "GET

I based my pom.xml in the pom.xml of the TOTP extension. I only changed the
artifactId, name and url and in the configurations for the angular-maven-plugin
and minify-maven-plugin, I replaced "totp" with "ndaw-crdp".

A listing of the contents of each .jar and the contents of their
guac-manifest.json files would also be helpful.
