Active Directory 访问规则不像 dsacls 那样具体

Question

所以我正在尝试从特定的 OU 获取 ACE 列表。我发现了 ActiveDirectoryAccess 规则 class.

输出给出的结果似乎不像 dsacls 命令的输出那样具体 (https://technet.microsoft.com/en-us/library/cc771151%28v=ws.11%29.aspx?f=255&MSPPError=-2147217396)

如何使我的 C# 代码获得更多类似于 dsacls 的描述性结果？（更好的显示名称）

这是我的测试输出结果的一个子集

Domain\myGroup
Inherits - Descendents
ObjectType - 00299570-246d-11d0-a768-00aa006e0529

ActiveDirectoryRights - ExtendedRight

ObjectFlags - ObjectAceTypePresent, InheritedObjectAceTypePresent
AccessControlType - Allow
ActiveDirectoryRights - ReadProperty, WriteProperty
IsInherited - True
PropagationFlags - InheritOnly

这是 dsacls 的输出

Allow Domain\myGroup         Reset Password   <Inherited from parent>
Allow Domain\myGroup         SPECIAL ACCESS for lockoutTime   <Inherited from parent>
                                      WRITE PROPERTY
                                      READ PROPERTY
Allow Domain\myGroup                  SPECIAL ACCESS for pwdLastSet   <Inherited from parent>
                                      WRITE PROPERTY
                                      READ PROPERTY

通过查看LDAP://cn=Extended-rights,CN=Configuration,Dc=Mydomain下的一些objecttype代码

我可以说 00299570-246d-11d0-a768-00aa006e0529 映射到重置密码但我找不到任何匹配 - 28630ebf-41d5-11d1-a9c1-0000f80367c1 或 bf967a0a-0de6-11d0-a285-00aa003049e2

获取特定 OU 的 ACE 输出的代码。

[Test]
        public void ForWhosebug()
        {
            var cfg = new DirectoryEntry("LDAP://PathToMyOU");
            var cfgsearch = new DirectorySearcher(cfg);

            cfgsearch.Filter = "(name=*)";
            cfgsearch.PropertiesToLoad.Add("distinguishedName");
            cfgsearch.SearchScope = SearchScope.Subtree;


            var res = cfgsearch.FindAll();

            var ouDE = res[0].GetDirectoryEntry();

            var accessRules = ouDE.ObjectSecurity.GetAccessRules(true, true, typeof(NTAccount));

            foreach (ActiveDirectoryAccessRule ar in accessRules)
            {
                Console.WriteLine($"{ar.IdentityReference.ToString()}");
                Console.WriteLine($"Inherits - {ar.InheritanceType.ToString()}");
                Console.WriteLine($"ObjectType - {ar.ObjectType.ToString()}");
                Console.WriteLine($"InheritedObjectType - {ar.InheritedObjectType.ToString()}");
                Console.WriteLine($"ObjectFlags - {ar.ObjectFlags.ToString()}");
                Console.WriteLine($"AccessControlType - {ar.AccessControlType.ToString()}");
                Console.WriteLine($"ActiveDirectoryRights - {ar.ActiveDirectoryRights.ToString()}");


                Console.WriteLine($"IsInherited - {ar.IsInherited.ToString()}");
                Console.WriteLine($"PropagationFlags - {ar.PropagationFlags.ToString()}");
                Console.WriteLine("-------");
            }
        }

我用来获取一些对象 guid displayname 的代码

[Test]
public void ForWhosebugAllExtendedRights()
{
    DirectoryEntry rootdse = new DirectoryEntry("LDAP://RootDSE");
    DirectoryEntry cfg = new DirectoryEntry("LDAP://" + rootdse.Properties["configurationnamingcontext"].Value);
    DirectoryEntry exRights = new DirectoryEntry("LDAP://cn=Extended-rights," + rootdse.Properties["configurationnamingcontext"].Value);
    Hashtable exRighthash = new Hashtable();

    foreach (DirectoryEntry chent in exRights.Children)
    {
        if (chent.Properties["rightsGuid"].Value != null && !exRighthash.ContainsKey(chent.Properties["rightsGuid"].Value))
        {
            exRighthash.Add(chent.Properties["rightsGuid"].Value, chent.Properties["DisplayName"].Value);
            Console.WriteLine($"{chent.Properties["rightsGuid"].Value}, {chent.Properties["DisplayName"].Value}");
        }
    }
}

更新 #1 我设法找到了一段代码（来自本书https://www.amazon.com/s/?url=search-alias=stripbooks&field-keywords=0321350170&tag=technicalibra-20&link_code=wql&camp=212361&creative=380601&_encoding=UTF-8）检查受影响的帐户类型。

我现在更接近了。有些条款不匹配（例如将密码重置为 User-Force-Change-Password），有些条款未显示

这是我之前示例的结果。

Some of the terms don't match (like reset password to User-Force-Change-Password) and some don't show up

对于扩展权限对象，您需要获取 displayName 属性而不是 CN：

public static string GetNameForRightsGuid(Guid rightsGuid, DirectoryEntry extendedRightsRoot)
{
    string filter = $"(rightsGuid={rightsGuid.ToString("D")})";
    return GetNameForGuid(filter, "displayName", extendedRightsRoot);
}

在您的示例中，结果为 "Reset Password"

Active Directory 访问规则不像 dsacls 那样具体

Active Directory Access Rules aren't as specific as dsacls

c#

active-directory

acl

access-rights
