Rabbitmq mqtt plugin how to set user permission
pascal defoort
We declare user for MQTT access.
How could we set permission to insure fine access control ?
User should be able only to consume message based on its MQTT subscription and optionally to publish message if explicily authorized.

Thank you Michael.
I noted that topic authorization will be provide only from 3.7.0.
For now, I wish to protect the broker and limit as such as possible the permission of a mqtt user.
How could I provision permission for dedicated MQTT user ?
What are the ressources to declare in read, write and configure permission ?

This has been discussed several times on this list in the last 6-12 months. I don't know how
you define "base on its MQTT subscription" but if it's topic based then you'll have to wait till 3.7.0.
Publishing happens over the amq.topic exchange by default. You can limit what users have the "write" permission to it:

I've mentioned it before but it's worth repeating: MQTT the protocol doesn't have provisions for authorization
or server-to-client error notifications, which makes authorization a major pain point for both implementers and users.

I don’t want to grant all permissions (read : « .* », write : « .* », configure : « .* ») to users dedicated to MQTT access.
The following combination work (read : « ^mqtt-subscription .* », write : « .* », configure : « .* ») but it is not enough restrictive.
Could you please give me examples of relevant permission set for a mqtt dedicated user with and without publish authorization?

See "How it Works" in http://www.rabbitmq.com/mqtt.html and www.rabbitmq.com/tutorials/amqp-concepts.html
if you are not familiar with exchanges vs. queues.
"Protecting the broker" usually goes well beyond authorization. You can use a separate vhost for
some apps, use a separate topic exchange with the MQTT plugin (covered in the docs) and restrict
access to it only for specific users.
Publishing and binding to that exchange should provide a decent level of restriction without getting really
complicated.

All relevant operations roughly come down to
read: mqtt-subscription* | amq.fanout
configure: mqtt-subscription*
write: mqtt-subscription* | amq.fanout
Limiting the "write" and "configure" permissions to just "mqtt-subscription.*"
should be sufficient to make it impossible for an MQTT client to publish anything
that can reach other MQTT clients.
(all the patterns above are not regular expressions, please figure it out what the
actual regular expressions should be)

I get the messages without error with the following settings :
read: .*
configure: mqtt-subscription*
write: mqtt-subscription*
So the problem is on the read operation.
When I set the read operation with « mqtt-subscription* », I got error.
