Yes.

This is exactly what paging allows.  Yes, it is client initiated.
This is a good thing.

The server needs to know that the client supports paged results
and needs to know when the client is ready for more results.

As such requires protocol extension, both clients and servers
will likely have to support LDAPv3 (which provides a framework
for extensions) and the specific extension to manage the
paging of results.
