The reason the server sends that response has already been indicated to 
you in 
<http://www.openldap.org/lists/openldap-software/200704/msg00016.html>.

As you were unable to take advantage of that simple suggestion, I infer 
you don't have enough understanding of the basics of LDAP, and of 
OpenLDAP, to implement what you're trying to obtain.

Furthermore, why on earth would you need to implement a broken and 
obsolete control like Persistent Search and LCUP when the LDAP Sync API 
already provides the similar but better functionality?

If you want to implement client-side PS using OpenLDAP's C API you'll 
need to develop your own functions and encode messages as specified by 
that spec.  If you want to implement server-side PS you'll need to do 
extensive work on the server side, which would essentially duplicate 
existing LDAP Content Synchronization code.  In any case, if you really 
want to implement PS, the LDAP Sync API will be of no use.
