Subject [jira] [Commented] (AMQ-6148) When use LDAP auth, Activemq should not always connect to ldap service to do authentication
Date Fri, 29 Jan 2016 02:45:39 GMT

    [ https://issues.apache.org/jira/browse/AMQ-6148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15122828#comment-15122828

Justin Bertram commented on AMQ-6148:
-------------------------------------

For what it's worth, [Apache ActiveMQ Artemis|http://activemq.apache.org/artemis/] (a sub-project
of Apache ActiveMQ) employs a caching mechanism so that whatever login module is being used
isn't called *every* time an authentication is performed.  It's controlled by a simple time-out.
 You can see the details in [org.apache.activemq.artemis.core.security.impl.SecurityStoreImpl|https://github.com/apache/activemq-artemis/blob/master/artemis-server/src/main/java/org/apache/activemq/artemis/core/security/impl/SecurityStoreImpl.java]

> I am using LDAP service to do authentication for ActiveMQ, and I found everytime ActiveMQ
servers try to establish a connection between ActiveMQ client, the ActiveMQ server will create
a connection to LDAP server to do authentication. That's is not good, think about there are
thousands of ActiveMQ clients are trying to connect to ActiveMQ servers, the ActiveMQ servers
will need to create thousands of connections to LDAP servers. And moreover it is not reliable
as well because the connection between LDAP servers and ActiveMQ servers could be broken sometimes.
We need something similar as Cached LDAP Authorization Module. It is more reasonable that
the ActiveMQ will cache the ldap account credential in local memory and refresh in certain
interval.
