php - 如果我不知道基本 DN 的 OU,如何使用 PHP ldap_search() 获取用户 OU

我有一个 Active-Directory 结构,其中用户对象驻留在 OU 中,例如 IT、技术、人力资源、帐户等。我想编写一个 PHP 脚本,使用 AD 对用户进行身份验证,并根据他们的组提供适当的网络服务。

ldap_search() 需要基本 DN。我尝试使用

进行搜索
ldap_search($ldap, "dc=country,dc=company,dc=co,dc=uk", "(samaccountname=$username)", array("memberof"));

但 PHP 给出“操作错误”。相反,如果我指定 OU

ldap_search($ldap, "ou=sales,dc=country,dc=company,dc=co,dc=uk", "(samaccountname=jake)", array("memberof"));

那么搜索就OK了。

我可以使用通配符吗?

顺便说一句,用户对象是否应该在 OU 中?因为我是一开始就把他们搬进去的菜鸟!

编辑:感谢 JPBlanc 为我指引正确的方向和 http://blog.redbranch.net/?p=76

解决办法是在connect和bind之间加两行。

ldap_connect(..)
ldap_set_option ($ldap, LDAP_OPT_REFERRALS, 0);
ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_bind(..)

谢谢 =)

<?php

ldap_close($ldap);

foreach($dc as $_dc) $base_dn .= "dc=".$_dc.",";
$base_dn = substr($base_dn, 0, -1);
$sr=ldap_search($ldap, $base_dn, "(&(objectClass=user)(objectCategory=person)(|(mail=*)(telephonenumber=*))(!(userAccountControl:1.2.840.113556.1.4.803:=2)))", array("cn", "dn", "memberof", "mail", "telephonenumber", "othertelephone", "mobile", "ipphone", "department", "title"));

return $users;

class User
{
var $auth_status = AuthStatus::FAIL;
var $username = "Anonymous";
var $password = "";

var $groups = Array();
var $dn = "";

public function __construct($username, $password)
{
$this->auth_status = AuthStatus::FAIL;
$this->username = $username;
$this->password = $password;
}

public function get_auth_status()
{
return $this->auth_status;
}
}
?>

用法:

$ldap = new ldap\LDAP("192.168.1.123", "company.com", "admin", "mypassword");
$users = $ldap->get_users();

最佳答案

如果您尝试在 Windows 2003 Server Active Directory 或更高版本上执行搜索,您似乎必须将 LDAP_OPT_REFERRALS 选项设置为 0:

ldap_set_option($ldap, LDAP_OPT_REFERRALS, 0);
ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);

没有这个,如果您尝试搜索整个 AD(使用域的根目录作为 $base_dn),您将收到“操作错误”。


在 LDAP 目录中,通常任何节点都可以在任何节点下(用户是节点,ou 是节点)。

但是 Active-Directory 的行为方式与 SCHEMA 定义的对象可以存在于哪个容器中的方式不同。因此,如果您寻找用户,允许的上级是:builtinDomaindomainDNSorganizationalUnit,如下所示:
