Assertion controls in the generated LDIF (...) This requires support for assertion controls in back-ldif/back-config, and some attribute for the assertion to test. Maybe an automatically maintained md5sum(contents of entry) attribute.
Or rather dynamically generated, since people might edit LDIFs in cn=config by hand if slapd won't start.
From an implicitly included overlay, I guess. (Lacking that, it could at least check modifyTimeStamp.)
