The parameters of ldap_result to not affect how the server responds to
requests, they affect how ldap_result behaves while parsing the server
provided results.  See ldap_result(3) for details.

Issue requests that result in smaller results, but...

As entries in containers are not orderred, I would suggest that one ldap search
be issued for each sequence of getgrent() calls made by application (sets
delimited by setgroupent()/setgrent()/endgrent calls).  One could use
ldap_result(all=0) to set through the results as needed for getgrent() or
use ldap_result(all=1) and ldap_first/next_entry().
