LDAP DN搜索成员 [英] LDAP DN search memberof

问题描述

当前，我正在尝试确定用户是否应该能够使用LDAP登录.我已经阅读了许多用PHP编写的LDAP连接，到目前为止，一切都进展顺利，直到我想搜索用户是否属于某个组为止.

Currently I'm trying to determine if a user should be able to login using LDAP. I've read up on many LDAP connections written in PHP and so far things were on track until I wanted to search if a user was part of a certain group.

我当前必须连接到LDAP服务器的详细信息:

• DN:CN = PAY LDAP用户，OU =付费，OU =应用程序，OU = IT 特价，DC = domain，DC = be
• SAM:管理员
• 密码:密码
• 搜索DN ADM:OU = OU GROUP，OU = AD，DC = domain，DC = be
• LDAP/GC服务器:knt-adm-dc1.domain.be，knt-adm-dc2.domain.be

• DN: CN=PAY LDAP user,OU=pay,OU=Applications,OU=IT Specials,DC=domain,DC=be
• SAM: admin
• PWD: password
• Search DN ADM: OU=OU GROUP,OU=AD,DC=domain,DC=be
• LDAP / GC server: knt-adm-dc1.domain.be, knt-adm-dc2.domain.be

此代码虽然没有返回任何结果:

This code though doesn't return me any results:

if($bind = ldap_bind($ldap, $username, $password)) {
    $filter = "(samaccountname=".$user.")";
    $attr = array("memberof");
    $result = ldap_search($ldap, $ldap_dn, $filter, $attr) or exit("Unable to search LDAP server");
    $entries = ldap_get_entries($ldap, $result);
    ldap_unbind($ldap);
}

当我从搜索中删除$ attr时，虽然没有找到确定此用户是否属于ADMIN组的方法，但我确实得到了结果.

When I leave out the $attr from the search I do get a result though I can't seem to find a way to determine of this user is part of the ADMIN group.

从我可以在线阅读的内容来看，应该使用memberof属性来确定用户是否属于组.

From what I could read online the memberof attribute should be used to find if a user is part of a group though.

推荐答案

几件事:

1. 如果用户不是任何组的成员，则memberOf属性将不存在.
2. 建筑物组未显示在memberOf属性中.

1. If a user is not a member of any groups, the memberOf attribute will not exist.
2. Builtin groups do not show up in the memberOf attribute.

一种更可靠的方法是使用有点模糊的LDAP过滤器为用户搜索您的组以及任何嵌套的组:LDAP_MATCHING_RULE_IN_CHAIN规则.详细信息此处.

A more failure-proof method is to use a somewhat obscure LDAP filter to search your group, and any nested groups, for a user: the LDAP_MATCHING_RULE_IN_CHAIN rule. Details here.

在PHP中，它看起来像这样(未经测试):

In PHP, it would look something like this (untested):

$filter = "(member:1.2.840.113556.1.4.1941:=".$user_distinguished_name.")";
$ldap_dn = "LDAP://".$group_distinguished_name;
$attr = array("cn");
$result = ldap_list($ldap, $ldap_dn, $filter, $attr);

其中$user_distinguished_name是用户的专有名称，$group_distinguished_name是组的DN.您可能需要事先获得这些.

Where $user_distinguished_name is the distinguished name of the user, and $group_distinguished_name is the DN of the group. You may have to get those beforehand.

请注意，我将 ldap_list 而不是 ldap_search .两者之间的唯一区别是搜索范围.我认为ldap_search可能仍然有效，但这不是必需的.

Note I'm put ldap_list instead of ldap_search. The only difference between the two is the scope of the search. I think ldap_search might still work, but it's not needed.
