Sounds good. Meanwhile I could use this syntax here too. After lowering 
tombstone lifetime at my setup running

samba-tool dbcheck --cross-ncs

resulted in

Checking 20970 objects
ERROR: wrong

Please use --fix to fix these errors
Checked 20970 objects (1 errors)

reran with --fix but it did not help. So I took an snapshot of al addc 
vm's and deleted the entry using your syntax

ldbdel -H /var/lib/samba/private/sam.ldb 
"<GUID=ce76b285-0ade-444b-b08c-e8b2f7c9fcf9>"

on all addc's.

Afterwards dbcheck passed and till now i have not seen replication errors.

Had tried to delete "Deleted Objects" before using -H 
/var/lib/samba/private/sam.ldb.d/DC=\DOMAINDNSZONES,DC=...ldb which was 
an bad idea, afterwards i could no longer add/delete or modify dns 
records. This does still work now and i wonder if this sytnax can be 
used to remove these hundreds of deleted DNS records for clients with 
dynamic ip's.

Anyway thanks for figuring this out.
