s4:dsdb: Make the linked_attributes module set an extended dn
This means that linked attributes will always have the same case form as the actaul entry, as we search for that entry. We then also use the GUID and SID found on that entry to fill in the extended DN on disk. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
