Hi Tim, I have more explanation but not the solution!!!
I found this bug: https://issues.jboss.org/browse/ENTMQ-1154 it's the same behavior for my point. I use (for my test) only activemq 5.15.1 (the latest 5.15.2 zip file is corrupt!) in standalone (without Karaf) I reproduce the issue! I use qpid messaging (latest) to try a connection with the broker. without <plugins><jaasDualAuthenticationPlugin configuration="activemq-domain" sslConfiguration="activemq-ssl-domain"/> </plugins> it's works, with this it's fail Regards -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
