Question

我有一个Active-Directory结构，其中User对象驻留在OU中，例如IT，Technical，HR，Accounts等。我想编写一个PHP脚本，用AD对用户进行身份验证，并根据他们的Group提供aproperiate web services。

ldap_search（）需要基本DN。我试着用

搜索

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

但是PHP给出了“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"));

然后搜索就可以了。

我可以使用通配符吗？

另一方面，用户对象应该在OU中吗？因为我是第一个把他们搬进去的菜鸟！

解决方案是在连接和绑定之间添加2行。

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

谢谢=）

?>

用法：

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

如果您尝试在Windows 2003 Server Active Directory或更高版本上执行搜索，则似乎必须将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);

如果没有这个，如果你试图搜索整个AD（使用域的根作为$ base_dn），你将得到“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行为不同。因此，如果您要查找用户，则允许的上级是：builtinDomain，domainDNS和organizationalUnit，如下所示：
