php - 递归显示用户所属的所有 Active Directory 组

Question

我有以下脚本检查 AD 访问权限，然后在特定组内检查成员资格。

如何显示用户有权访问的每个组，包括不直接访问的组 - 例如 - 用户 - userA，在组 - groupA，以及 groupB 中的 groupA，我希望它也显示 groupB作为A组

我错过了什么？

在您的 inGroup 方法中，将其用于您的过滤器:

$filter = "(&(distinguishedName=$groupToFind)(member:1.2.840.113556.1.4.1941:=$userDN))";

将首先通过 DN 选择组，然后通过其 DN 递归地检查它是否包含成员。

编辑

如果您希望搜索返回用户所属的所有组，请使用此过滤器:

$filter = "(&(objectClass=group)(member:1.2.840.113556.1.4.1941:=$userDN))";

喜欢:

$filter = "(&(objectClass=group)(member:1.2.840.113556.1.4.1941:=$userDN))";
$search = ldap_search($ldapConnection, 'DC=registry,DC=otago,DC=ac,DC=nz', $filter, array("cn"));

$allGroups = ldap_get_entries($ldapConnection, $search);

上面的$allGroups 将包含用户直接或间接属于的每个组(例如属于不同组的组等)。但是，DC=registry,DC=otago,DC=ac,DC=nz 真的是您域的“基本”级别吗？这应该是 ldap_search 的第二个参数。
