在使用 IE/Firefox 时使用 PHP、活动目录对 ldap 进行身份验证

This code below checks for the user's credentials against ldap

<?php
$ldaphost = "ldap.domain.com";
$ldapport = 389;

$ds = ldap_connect($ldaphost, $ldapport)
or die("Could not connect to $ldaphost");

if ($ds) 
{
    $username = "johndoe@domain.com";
    $upasswd = "pass";

    $ldapbind = ldap_bind($ds, $username, $upasswd);

    if ($ldapbind) 
        {print "Congratulations! $username is authenticated.";}
    else 
        {print "Access Denied!";}
}
?>

我的用户使用 Firefox 和 IE，我知道它们可以无缝传递他们的 ActiveDirectory 凭据.
