title: How can I use different authentication methods for different MQTT endpoints? [Mosquitto]
body: <p>I have a Mosquitto MQTT Broker, configured for Websockets on one port, and mqtt over another.</p>
  <p>I have a custom authentication plugin, and it works well. What I want, however, is that only clients connecting over websockets use my plugin, and clients connecting over mqtt protocol use the default TLS authentication.</p>
  <p>I am hoping there is some simple setting I have overlooked that I can add to the configuration file, but any/all solutions are welcome. Many thanks.</p>
