In OpenLDAP you would set an equality index on uidNumber and do a query for,
e.g., (uidNumber<=2147483647) with sizelimit=1.
What? That only finds the max uidNumber when you already know an
almost-max value, so you can fill it into the filter. Without that
you'd need to guess an upper limit and do a binary search. (Though you
could use a sizelimit > 1 for that.)
