Ok, why not. But LDAP does not provide such a mechanism. Even if the
search engine knows about how many entries are going to be returned I
see no standard way to send it back to the requester (it would require a
dedicated control or extended operation).

What I would see as a valid requirement is to keep a track of all
operations that have been done on an audit part of the DIrectory server,
with informations like the number of returned entries.

OTOH, such demand are pretty equivalent to people wanting to do
something likle a SQL "select count(*) ..." which is frequently severly
abused request (how many times have I seen people writing code that
first does a select count(*) before doing the same request again,
allegedly to "know about the number of elements I will get back, to
correctly manage my web page presentation" ?)

You are likely to hit the configured limit anyway...
