Hi ,
        I am trying to syncing up with Active directory. When ever there  
is a change in active directory it should send the information.
But It's keep on sending me this error message .


errorMessage: 00000057: LdapErr: DSID-0C09068F, comment: Error processing  
control, data 0, vece


LDAP_SERVER_NOTIFICATION_OID_W  "1.2.840.113556.1.4.528"

char* base="dc=ad,dc=hello123,dc=com";
char* filter="(objectClass=*)";


 controls[0] = create_psearch_control (LDAP_SERVER_NOTIFICATION_OID_W, 1,  
1);
 controls[1] =  0;


ret = ldap_search_ext (ld, base,
                           LDAP_SCOPE_SUBTREE,
                           filter,
                           0,      /* attrs       */
                           0,         /* attrsonly   */
                           controls,
                           0,      /* clientctrls */
                           0,      /* timeout     */
                           LDAP_NO_LIMIT,
                           &msgid);



 while ((ret = ldap_result (ld, msgid, LDAP_MSG_RECEIVED, &timeout,  
&entries)) >= 0) {
        LDAPMessage  *entry;
        LDAPControl **ec_controls;

        if (!ret) {
            printf ("Timed out\n");
            continue;
        }

}

Please let me know what I am doing wrong.
