Hi Hugh, If you have some time to try and implement it, start from SyncReplSourceService.java class and look at the getNextId() method which is storing results inside a temporary map. Don't implement IAsynchronousService if you do not plan to use the event based model, but use this idea inside a subclass of SimpleJndiService in which you should override the getBean method.
You will have to build the same map and before returning any result, sort the map according the DN hierarchy through for example the following method : http://directory.apache.org/api/gen-docs/latest/apidocs/org/apache/directory/shared/ldap/model/name/Dn.html#isAncestorOf(org.apache.directory.shared.ldap.model.name.Dn Regards, -- Sebastien BAHLOUL IAM / Security specialist Ldap Synchronization Connector : http://lsc-project.org Blog : http://sbahloul.wordpress.com/ 2012/4/24 Hugh Kelley <[email protected]> > I do plan to run the sync as a recurring job (cron-like) but the > destination directory is currently empty. > > Is it AbstractSimpleJndiService that you are proposing I customize > (specifically the SearchResult property or thereabouts)? > > Hugh > > > On Tue, Apr 24, 2012 at 12:19 PM, Sébastien Bahloul < > [email protected]> wrote: > >> Hi Clement, Hugh, >> >> The builtin LDAP source service is effectively not designed to handle >> such use case.
