We are building an LDAP client application based on the sample clients
provided in the ldap/clients/tools directory.

When we try either our application or the original sample clients on public
directories such as BigFoot, WhoWhere, ..., we only receive partial results
to our search requests.

For BigFoot, we receive 40 entries. For WhoWhere, we receive 100...

On a local directory, we receive a full list (if there are 500 entries matching
the filter, we get 500 entries in result).

So apparently, the public LDAP directories place a limit to the number of
entries
they return.

Netscape Search and Outlook Express Search display the same problems and return
only partial results.

I have seen an application (EmailFerret from FerretSoft - www.ferretsoft.com)
that
manages to retrieve more entries than the limit placed by the server, apparently

10 by 10 until there are no more results.

How can this be done ?

Thanks in advance.
