All authentication related properties are optional. By default no authentication is used. As soon as you provide a username, authentication is set up. Please note that you should then at least provide truststoreType, truststorePath and truststorePassword. To use client certificate authentication, set keystoreType, keystorePath, keystorePassword and keyPassword.
