From eb0421c471342edfe4900fbd9d5b9fd9a7c650d8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix several schema checking issues; add rename specific
 statement for entry renaming without losing ID (helps e.g. in renaming
 referrals, otherwise referential integrity would prevent del/add because of
 referenced stuff in ldap_referrals and ldap_entry_objclasses); referrals need
 schemacheck off otherwise objectClass chain is invalid (they need to be
 attached to another objectClass by now; will address this later)
