openldap: Sizelimit exceeded problem

[Leon Vernikov <vernikov@cisco.com>]

Hello,

I need your help to resolve "Sizelimit exceeded" problem
1. LDAP server runs  openldap v.2.0.9
    Please see configuration of slapd.conf bellow
    I set line in slapd.conf
    sizelimit 500
    explicitly.

2. I used the ldapsearch utility to query database. It returns 2
records.
    I attached the result of search bellow.

3. My application runs LDAP API ldap_search_s with ldapsearch parameters

    base dc=test,dc=com
    filter (member=cn=Penny Gold,dc=test,dc=com)
    rc = ldap_search_s (session->ld, session->conf->base,
                       session->conf->scope, filter, NULL, 0, &res);
    It returns an error
    Error LDAP search_s Sizelimit exceeded

Would you, please, help me to understand the problem?
Thank you,

Leon
