To enable Change Log on Apache Directory server

We referred the below mentioned links but we're not able to configure Change Log on Apache directory server. Can you please provide us step by step guide on how to enable change log or Change tracking mechanism so that we can get the delta changes from Apache directory server.

Its a blocking for us as its hindering us to implement Delta Import feature for the Apache directory. We can not find any adequate resource on Internet describing the steps to configure Change log.

Any help in this regard will be highly appreciated.
