Hi,

I have a pretty big database (hdb, 300 000 entries) with low memory (1/4 GB).
If I try a search with scope sub, base dc=suffix, and filter
(entryDN=uid=nonexisting,dc=people,dc=suffix), the search is very slow (I
stopped after some minutes).
But if I try with scope base, base uid=nonexisting,dc=people,dc=suffix, filter
(objectClass=*), the result is immediate, telling there is no such entry.

I have read that since 2.4.13 entryDN is indexed by dn2id, but it doesn't seem
to be the case.

Regards,
Raphaël Ouazana.

PS : my test database run OpenLDAP 2.4.26 only, but I have not seen any change
in the area of entryDN indexing. Will try with 2.4.37 if you think something has
changed.
