If an entry is edited by a plug-in or by the server, rather than a Directory Server user, this attribute records what internal user (by plug-in DN) modified the entry.

The internalModifiersname attributes always show a plug-in as the identity. This plug-in could be an additional plug-in, such as the MemberOf Plug-in. If the change is made by the core Directory Server, then the plug-in is the database plug-in, cn=ldbm database,cn=plugins,cn=config.
