Overview#

Changelog typically refers to the concept by which all LDAP Server operations are written to a special kind of database that is used by some LDAP Server Implementations to keep track of the changes that occur in a Directory System Agent instance.

Many Changelogs are implemented in a proprietary method and do not follow any published standard.

The Definition of an Object Class to Hold LDAP Change Records is the attempt to make the Changelog format a standard.
