Another paged result question

["Armbrust, Daniel C." <Armbrust.Daniel@mayo.edu>]

The paged result response control has a field that returns the result size.

The RFC for paged results says that this may be an estimate - not the real number.  In the openldap implementation, does anyone know if this is an estimate, or is it supposed to be the real number of results?

The reason that I ask is that sometimes it seems to line up perfectly with the actual number of results I get, but other times it doesn't seem to line up.  For example, I have had it tell me that there would be 1319099 results, while I only got 728842 results.  I didn't get any errors, but given the previously noted flakey behavior of paged searches, I'm wondering if it just skipped some.
