Support for MQTT authentication

Hi,

Is there any way to create a route to an authenticated mqtt broker ?

"Failed to create route mqtt... due to: Could not connect:
CONNECTION_REFUSED_SERVER_UNAVAILABLE"

Are there plans to implement MQTT authentication in MQTTComponent as
specified by the protocol ?

Thanks.
