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.
