!!! Overview
Referential integrity is a mechanism for ensuring that any references to an entry are updated whenever that entry is removed or altered.  Historically, referential integrity is primarily used to ensure that attributes with a [DN] syntax (especially group membership attributes like {{member}} and {{uniqueMember}}) are properly maintained in the event of [delete|Definition -- LDAP Delete Operation] and [modify DN|Definition -- LDAP Modify DN operation|ModifyDNRequest] operations.  For a delete operation, any references to the target entry will be removed.  For modify [DN] operations, any references to the target entry will be renamed accordingly.
