ldap “The search filter is bad.” error from MSDN c++ example

Question

i running a LDAP example in c++ from MSDN . I posting this because I have no idea. The code connect and bind just fine, but when I run a search operation bad search filter error arise, the strange is I am running the basic filter: "(objectClass=*)" from MSDN tutorial. here is the code:

            #include "stdafx.h"

            #include <windows.h>
            #include <ntldap.h>
