Portal: 2.2.1SP3 AS: 4.0.4GA bundled download There does not seem to be any way to define the Portal mbean's to stack authentication in the jboss-service.xml as you can in the login-config.xml. The UserModule and RoleModule mbeans can be configured with contexts and filters that work for a single LDAP server, but a user authenticated through a secondary LDAP with a different structure will fail in the mbean. How can multiple LDAP servers be defined to work with the Portal? Has this problem been encountered and already solved in a newer Portal release?
