Here is the thing: after a client connects to the broker without ending its connection, it can never be kicked out even if I changed the authentication on the broker side.
So is there any way for a broker to end a connection between him and a client without restarting the server?
You can manually go in through JMX and find the connection and terminate it (I think). But if you change the authentication on the broker side, don’t you need to restart the broker to pick up those changes?
