Mosquitto broker not able to use access control

Question

Here are my contents of acl_file

user client1
pattern read client2_topic

user client2
pattern write client2_topic

user client3
topic hello

I tried publishing message to topic test from client3 and he is publishing it.

I don't want any access to topics other than client2_topic and hello .

Answer 1

You should change pattern to topic . pattern applies to all clients and you would expect to see either %c or %u in the pattern string, otherwise there is no point to it.
