-----------------------------------
Summary: Validate against cluster user name uniqueness
Key: ARTEMIS-2959
URL: https://issues.apache.org/jira/browse/ARTEMIS-2959
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Affects Versions: 2.15.0
Reporter: Howard Gao
Fix For: 2.16.0
The broker has a special cluster user and cluster password and when doing
authentication it always check the cluster user first.
If user configures a cluster user name that is the same as one of it's
normal users, the broker always authenticate that normal user
against the cluster password which is not right and probably failed
authentication as the cluster password usually not the same as
the normal user's password.
To avoid such a case the broker should check the configuration
during startup and if the cluster user name collides with a normal
user name, it should report as an error.
