Yes.  And OpenLDAP also honors admin enforced limits, so if the
sizelimit on the server is set to N, no matter how you collect entries
(all in a bunch or paged one by one), you won't be able to get more than
N (if you can, that's a bug; please let us know).

If your question was: can I use pagedResults to circumvent those
implementations of DSAs that allow its use to circumvent server imposed
admin limits (like AD, for example)?  The answer is: yes.  But OpenLDAP
dos not provide any C API calls to encode/parse pagedResults
requests/responses, you'll need to code them yourself maybe following
the ldapsearch.c implementation as a guideline.
