I guess I was right, it my code who had bug not the API :) I need to do this
:
for ( entry = ldap_first_entry(ld,ldapResponse);entry != NULL && count <
numEntries;
* entry = ldap_next_entry(ld,entry)*)
instead of
for ( entry = ldap_first_entry(ld,ldapResponse);entry != NULL && count <
numEntries;
* entry = ldap_next_entry(ld,ldapResponse))
*thanks for the help.
*
