Thanks for your reply once again.
Unless I've interpreted this incorrectly -
http://www.rabbitmq.com/access-control.html - the reference here says that
queue.bind is controlled via <write> (to queue) and <read> (from exchange).
I ran set permission for guest user, set <conf> to "testqueue".
//set_permissions [-p <vhostpath>] <user> <conf> <write> <read>
rabbitmqctl set_permissions guest "testqueue" "amq.default" "testqueue"
After that, I tried sending to "testqueue1", and got the following error.
"access to queue 'testqueue1' in vhost '/' refused for user
This test proves that I can limit a user to accessing a specific queue only
(be it to send to or to subscribe to) by limiting the configure operation to
To allow the guest user to be able to "only" send to "testqueue1", and as
well as be able to "only" read from "testqueue2", I try the following:
rabbitmqctl set_permissions guest "^(testqueue1|testqueue2)$" "amq.default"
However, this will give permission to the guest user to send to "testqueue2"
(I only want guest user to read from "testqueue2").
If I were to remove "testqueue2" from <conf>, guest user won't be able to
send to "testqueue2" but will also be unable to read from "testqueue2" - the
following error appears:
=ERROR REPORT==== 23-Feb-2014::16:08:03 ===
connection <0.1780.0>, channel 1 - soft error:
"access to queue 'testqueue2' in vhost '/' refused for user
How can I allow a user to only be able to read from a specific queue while
be able to send to another queue at the same time?
