mqtt subscribe disallow does not trigger disconnect

PubSub+ Event Broker
1

Hello,

i defined such a “subscribe acl” .

I tested with paho mqtt client and can subscribe also not allowed topic without disconnect.

Can anyone say, why i’m not disconnected during subscibe not allowed topic ?

(i expect a disconnect, but this does not occur.)

…because if i try publish not allowed topic, there is a disconnect from solace broker, as i expect.

show acl-profile **** message-vpn **** detail

Profile Name : vehicle_prod_ap

Vpn Name   : vpn
 Client Connect Default Action : allow
  Exceptions : 0
 Publish Topic Default Action : disallow
  Exceptions : 1

Hi Matthias,
As you are using a Paho client, you should switch the syntax of your ACL exception to MQTT from SMF. Notice the syntax of the expression as well as the MQTT choice in the syntax dropdown.

Hello,
Thx Matthew.
I can see all my things work, except disconnect on fail topic subscribe.
How can i trigger also a disconnect on “not correct topic” subscribe ?
…that’s the question.
let’s make as joke: to be or not to be… incl. disconnect - Howto ?
:wink:

Hi Matthias,
You won’t be disconnected on the “not correct topic” subscribe. An exception will be thrown back to the client, and you can choose how to handle it such as “disconnect.”
