Hi Domenico, > maybe this issue is due to the cache, see > https://github.com/apache/activemq-artemis/blob/2.31.0/artemis-server/src/main/java/org/apache/activemq/artemis/core/security/impl/SecurityStoreImpl.java#L409 > > Could you try to clear the authentication cache using the operation > clearAuthenticationCache?
It helped. After executing clearAuthenticationCache opertation, I have successfully sent a message without entering username and password. But when I checked later, I've got previous error. I have cleared authentication cache serveral times and tried to send messages through console. It seems that I can send message immediately after clearing cache, and 5-30 seconds after that operation. There are settings in broker.xml: authentication-cache-size: 10000 authorization-cache-size: 10000 security-invalidation-interval: 120000 When I configured LDAP authentication several months ago, I have increased both caches size from default (1000), but I don't know if it is small or large for our environment, and how to check it's usage. It is a shared instance for testing in development environment, and there is a lot of user logon events. I have also increased security invalidation interval to minimize LDAP servers load. Maybe these settings has effect on this problem. -- Best regards, Aleksandr ----------------------------------- This message and any attachment are confidential and may be privileged or otherwise protected from disclosure.
