GetAuthorizationGroups() 抛出异常

问题描述

PrincipalContext context = new PrincipalContext(ContextType.Domain, "ipofmachine", "DC=xyz,DC=org", "username", "Password");

UserPrincipal userPrinciple = UserPrincipal.FindByIdentity(context, "User0"); 
var groups = userPrinciple.GetAuthorizationGroups();

if (userPrinciple != null)
{
    foreach (GroupPrincipal gp in groups)
    {
        //some thing
    }
}

我需要给予任何许可吗?在一些博客中，我了解到如果没有设置为包含 SID 历史记录的用户，那么这将正常工作(但我认为您无法编辑组的 sid 值)

Is there any permission that I need to give? In some of the blogs I learned that if there are no users which are set to include the SID history then this will work fine (but i think you can not edit the sid values of the groups)

推荐答案

我发现将域用户添加到本地组时存在问题，但后来该域用户从 Active Directory 中删除.该本地组的状态是使用 SID 而不是显示为成员的域用户名.

I've found there's an issue when you add a domain user to a local group, but later that domain user is deleted out of Active Directory. The state of that local group is that instead of a domain username showing up as a member, the SID is used instead.

但是！

该 SID 不再存在于 Active Directory 中，这导致事情变得繁荣起来.

That SID doesn't exist in Active Directory anymore causing things to go boom.

当然，弹出 NoMatchingPrincipalException 的原因可能有很多，因此此代码提供了一种解决方法.它来自 MSDN 上的一篇很棒的帖子.下面的代码是在这里找到的修改版本:

Of course there could be many other reasons for an NoMatchingPrincipalException to pop up, so this code provides a workaround for that. It comes from a terrific post on MSDN. The code below is a modified version found here:
