implementing changlog in openldap

[nomit babraa <h.babraa@sheffield.ac.uk>]

Hi

We are using open ldap (sorry don't have access to the version at the
moment) and were wondering if there is any support for creating a
changelog that is available at cn=changelog?

We have a third party system that could use this changelog for
monitoring event driven changes and I've had difficulty googling
anything that sounds officially supported?

Thanks for any advice.
