Hello, So far I've been happy connecting to Artemis using either the Artemis JMS (CORE protocol) or with QPid JMS (AMQP protocol). But attempts with using Python QpidProton (AMQP protocol) are only successful when an anonymous user is allowed, but I actually need username+password. I now did a Wireshark trace to see what happened when a username+password is used:
Client <---> broker =============== --> Protocol header 1-0-0 <-- Protocol header 1-0-0 sasl.mechanisms(PLAIN+ANONYMOUS) --> sasl.init ANONYMOUS <-- sasl.outcome OK --> Protocol header 1-0-0 open begin attach(correct client-id and correct address) <-- Protocol header 1-0-0 --> open close(error-desciption=NullPointerException) --> close First observation is that Artemis is returning "NullPointerException" in the description of the 'close' sub-packet. The Artemis logfile shows a real NPE in location "org.apache.activemq.artemis.protocol.amqp.broker.AMQPSessionCallback.getAddress(AMQPSessionCallback.java:724)" for that. I'm not sure whether that is a bug, or just some unpolished code. Second observation is that Artemis offers the PLAIN+ANONYMOUS mechanisms. But my server only has "PropertiesLoginModule required" in etc/login.config, which does not actually allow anonymous login. I'm not sure whether that is a bug, or just an incorrect expectation from my side. Does anyone have useful remarks on these 2 observations? Does anyone have a working Python QpidProton client that uses username+password? thx, Erwin
