Hi all I don't have the same behavior between python-qpid-proton under Linux and WIN10.
I'm trying to authenticate with a user "access1" to send messages on an exampleQueue. With the same configuration, it works under WIN10 but not under Linux. etc/login.config activemq { org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule required debug=true reload=true org.apache.activemq.jaas.properties.user="artemis-users.properties" org.apache.activemq.jaas.properties.role="artemis-roles.properties"; }; With artemis CLI (using java) it's works for both OS. ./artemis producer --url amqp://localhost:5676 --destination exampleQueue --user access1 --password access1 --message "salut" --protocol amqp --message-count 4 --clientID sender1 --verboseExecuting org.apache.activemq.artemis.cli.commands.messages.Producer producer --url amqp://localhost:5676 --destination exampleQueue --user access1 --password access1 --message salut --protocol amqp --message-count 4 --clientID sender1 --verbose Home::/opt/apache-artemis-2.31.2, # Version client and Artemis broker Linux (repo amq-clients-2-for-rhel-8-x86_64-rpms ;yum install python3-qpid-proton) python-qpid-proton (0.37.0) --> broker apache-artemis-2.31.2 Windows10 (pip install) python-qpid-proton-0.39.0.tar.gz --> broker apache-artemis-2.31.2 My python test urlh="localhost:5672" cur_address="exampleQueue" # To connect with a user and password: cur_conn = event.container.connect(urlh, user="access1", password="access1") See the log on Linux with the python code (sender). 2024-01-22 14:01:50,864 INFO [org.apache.activemq.artemis.core.server.plugin.impl] AMQ841000: created connection: org.apache.activemq.artemis.protocol.amqp.broker.ActiveMQProtonRemotingConnection@1fc3c919<mailto:org.apache.activemq.artemis.protocol.amqp.broker.ActiveMQProtonRemotingConnection@1fc3c919> 2024-01-22 14:01:50,911 INFO [org.apache.activemq.artemis.core.server.plugin.impl] AMQ841010: routed message with ID: 427, result: NO_BINDINGS 2024-01-22 14:01:50,921 WARN [org.apache.activemq.artemis.core.server] AMQ222216: Security problem while authenticating: AMQ229031: Unable to validate user from /127.0.0.1:57226.

On WIN10, the user/password is sent correctly. Do you have an idea?
