I'm following this tutorial to configure mosquitto. This means that I'm storing my local configuration in /etc/mosquitto/conf.d/default.conf. However, I've just now realized that I can put any password/username and it will access mosquitto meaning my config file isn't taken into account. I've just now discovered the /etc/mosquitto.conf and it looks like this.
Do I need to mention the path for my local config file and how do I do it?
