LDAP on XAMPP localhost - ldap

Question

I am using windows XP with XAMPP 1.6.4 - php 5.2.4 with LDAP enabled
trying this script :
$server = "ldap://127.0.0.1/";
$user = "Salman";
$pass = "123";
$con = ldap_connect($server);
ldap_set_option($con, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($con, LDAP_OPT_REFERRALS, 0);
var_dump(ldap_bind($con, $user, $pass));
but ldap_bind always returns this error :
Warning: ldap_bind() [function.ldap-bind]: Unable to bind to server: Can't contact LDAP server in D:\xampp\htdocs\test.php on line 11
bool(false)

Hi i put a class together for this a while back:
<?php
/* USAGE:
* $ldapObj= new Ldap("HOST","PORT","USERNAME","PASSWORD","Distinguished Name"," (mailnickname=USERNAME)",array("*"));
*/
class Ldap {
enter code here
public $ldaphost;
public $ldapport;
public $ldaprdn;
public $ldappass;
public $dn;
public $filter;
public $attributes;
public $ad;
public $ldapbind;
public $ldapresults;
public $ldapentries;
public $ldaperror;
public $ldapstatus;
function __construct($ldaphost, $ldapport, $ldaprdn, $ldappass, $dn, $filter, $attributes) {
$this->ldaphost = $ldaphost;
$this->ldapport = $ldapport;
$this->ldaprdn = $ldaprdn;
$this->ldappass = $ldappass;
$this->dn = $dn;
$this->filter = $filter;
$this->attributes = $attributes;
$this->ad = ldap_connect($this->ldaphost);
if ($this->ad) {

$this->getSid();

} else {

$this->ldapstatus = 0;
}
ldap_unbind($this->ad);
} else {
$this->ldaperror = "Could not connect to {$this->ldaphost}";

}
}
function getLdapEntry($entry) {

}

function getSid() {
$sid = "S-";

// Convert Bin to Hex and split into byte chunks
$sidinhex = str_split(bin2hex($entries[0]['objectsid'][0]), 2);
