Dear ActiveMQ people,
we have a neatly working setup of several ActiveMQ 5 brokers which rely on an LDAP server for authorization. The configuration in activemq.xml looks roughly like this (some parts omitted): <plugins> <jaasAuthenticationPlugin configuration="LdapConfiguration" /> <authorizationPlugin> <map> <cachedLDAPAuthorizationMap connectionURL="ldap://my.ldap.server:389" connectionUsername="..." connectionPassword="..." queueSearchBase="..." topicSearchBase="..." tempSearchBase="..." refreshInterval="300000" legacyGroupMapping="false" groupObjectClass="groupOfNames" permissionGroupMemberAttribute="member" userObjectClass="person" userNameAttribute="uid" /> </map> </authorizationPlugin> </plugins> Now we plan to add some redundancy / high-availability for the LDAP part by using two or more mirrored LDAP servers. My simple question is: Does ActiveMQ have support for working with multiple LDAP servers? The documentation at https://activemq.apache.org/cached-ldap-authorization-module does not give any hint on whether the connectionURL can specify multiple servers. However I found another reference to the JAAS LDAP Login Module at https://access.redhat.com/documentation/en-us/red_hat_jboss_a-mq/6.3/html/security_guide/esbsecurecontainer#JAASAuth-LDAPLoginModule, which seems to indicate that connection.url may specify multiple URLs as a space-separated list. Can I expect that to work also in the ActiveMQ context?
