replication was setup yesterday and worked fine. Today after is not work.
Configuration is as follows:
1. To set up the provider (master) an replication handler must be specified and is done by adding the attribute ads-replReqHandler with the value org.apache.directory.server.ldap.replication.provider.SyncReplRequestHandler to the LDAP server entry ads-serverId=ldapServer,ou=servers,ads-directoryServiceId=default,ou=config. This will activate the module for listening to "LDAP Content Synchronization"-requests after the server is restarted.
