OpenLDAP builds a query tree from filters, but incorporates subtree search as
well as internal conditions into that tree that use equality tests on
onjectClass.  If a query should be accelerated by an index, "index eq
objectClass" must be used as well.

Please update the manuals slapd-ldbm and slapd-bdb to tell people that if they
use any index at all, the above index must be configured as well to see any gain
in performance.
