      Description

      We have the following setup:

      MQTT client (reproducible with at least mosquitto and fusesource) with cleanSession = false and QOS = 1 (important!)

      AMQ with authentication/authorization plugin

              <plugins>
                <statisticsBrokerPlugin/>
      
                <simpleAuthenticationPlugin>
                  <users>
                    <authenticationUser username="${activemq.username}" password="${activemq.password}" groups="admins,everyone"/>
                    <authenticationUser username="mcollective" password="secret" groups="mcollective,admins,everyone"/>
                  </users>
                </simpleAuthenticationPlugin>
                <authorizationPlugin>
                  <map>
                    <authorizationMap>
                      <authorizationEntries>
                        <authorizationEntry queue=">" write="admins" read="admins" admin="admins" />
                        <authorizationEntry topic=">" write="admins" read="admins" admin="admins" />
                        <authorizationEntry topic="mcollective.>" write="mcollective" read="mcollective" admin="mcollective" />
                        <authorizationEntry queue="mcollective.>" write="mcollective" read="mcollective" admin="mcollective" />
                        <authorizationEntry topic="ActiveMQ.Advisory.>" read="everyone" write="everyone" admin="everyone"/>
                      </authorizationEntries>
                    </authorizationMap>
                  </map>
                </authorizationPlugin>
              </plugins>
      

      No problem to connect for the first time, but when reconnecting with the same client ID, the connection fails each time:
