Reading AD / LDAP with PHP class

[Ecky]

With Exchange 5.5 I could read the LDAP with this class (written in PHP):

if (!$this->_connection)
$this->_connection=$this->ldap($_host,$_port);
ldap_set_option($this->_connection, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_get_option($this->_connection, LDAP_OPT_PROTOCOL_VERSION, $version);
// echo "version:" . $version, "<BR>";
$ctrl1 = array("oid" => "1.2.840.113556.1.4.302", "iscritical" => FALSE);
// iscritical defaults to FALSE
$ctrl2 = array("oid" => "1.2.840.113556.1.4.302");

Recently we migrated to Exchange 2003, and now I get this error:

Warning: ldap_bind(): Unable to bind to server: Invalid credentials in D:\Inetpub\

http://wwwroot\rtz\applicaties\batches\src\class.ldap.php

on line 82
Error Occurred:When: Login failed for dn= cn=INTEGRA\admin, dc=INTEGRA, dc=en
Errorno: 0
Text: Invalid credentials

I checked the credentials and can logon with them. I think it's in the class.
Does anyone have a new class or a new array like "1.2.840.113556.1.4.302" ?
