GetAuthorizationGroups（）引发异常 [英] GetAuthorizationGroups() is throwing exception

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
    }
}

我需要授予任何许可吗？在一些博客中，我了解到，如果没有用户设置为包含SID历史记录，则可以正常工作（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出现问题，但是后来将该域用户从Active Directory中删除了。该本地组的状态是使用SID代替域用户名显示为成员。

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.

BUT！

该Active Directory中不再存在该SID，导致事情发展。

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

当然，NoMatchingPrincipalException可能有许多其他原因弹出，因此此代码为此提供了一种解决方法。它来自MSDN上的精彩文章。下面的代码是在此处找到的修改后的版本：

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:

    public static IEnumerable<Principal> getAuthorizationGroups(UserPrincipal user)
    {
        PrincipalSearchResult<Principal> groups = user.GetAuthorizationGroups();
        List<Principal> ret = new List<Principal>();
        var iterGroup = groups.GetEnumerator();
        using (iterGroup)
        {
            while (iterGroup.MoveNext())
            {
                try
                {
                    Principal p = iterGroup.Current;
                    Console.WriteLine(p.Name);
                    ret.Add(p);
                }
                catch (NoMatchingPrincipalException pex)
                {
                    continue;
                }
            }
        }
        return ret;
    }
