列出Active Directory中的所有UPN后缀 [英] List all UPN Suffixes from Active Directory

问题描述

我正在尝试使用C＃从AD中获取所有upnsuffixes的列表。

I'm trying to get a list of all upnsuffixes from AD using C#.

我尝试失败了

public static List<string> GetuPNSuffixes()
{
    DirectoryEntry partitions = new DirectoryEntry("LDAP://xxxxx.com/CN=Partitions,CN=Configuration,DC=xxxxx,DC=com", "user", "pass");
    DirectorySearcher searcher = new DirectorySearcher(partitions);
    searcher.PropertiesToLoad.Add("uPNSuffixes");

    List<string> suffixes = new List<string>();

    foreach (SearchResult sr in searcher.FindAll())
    {
        foreach (string pn in sr.Properties.PropertyNames)
        {
            if (pn == "upnsuffixes")
            {
                suffixes.Add(sr.Properties[pn].ToString());
            }
        }
    }

    return suffixes;
}

这给了我一个 System.DirectoryServices.DirectoryServicesCOMException：服务器上没有这样的对象错误。我猜是因为它不喜欢我的ldap字符串。我要通过身份验证的帐户是域管理员，并且我在其他地方使用了类似的代码，因此登录名绝对正确。也许 CN = Partitions，CN = Configuration 部分错了？

This gives me a System.DirectoryServices.DirectoryServicesCOMException: There is no such object on the server error. I guess because it doesn't like my ldap string. The account I'm authenticating with is a domain admin and I'm using similar code in other places so the login is definitely correct. Maybe the CN=Partitions,CN=Configuration part is wrong?

我希望有更好的方法做到这一点而无需嵌套循环。只是尝试获取upnsuffixes的列表。

I would hope there is a better way to do this without the nested loops. Just trying to get a list of the upnsuffixes.

也尝试了此操作，并得到了相同的DirectoryServicesCOMException错误：

Also tried this and got the same DirectoryServicesCOMException error:

public static string GetuPNSuffixes()
{
    DirectoryEntry entry = new DirectoryEntry("LDAP://xxxxx.com/CN=Partitions,CN=Configuration,DC=xxxxx,DC=com", "user", "pass");

    return entry.Properties["upnSuffixes"].ToString();
}

所以我想我在这里用LDAP字符串做错了什么。

So I guess I'm doing something wrong here with the LDAP string there.

推荐答案

能够通过以下方式提取UPN后缀列表：

Was able to pull the list of UPN Suffixes with this:

public static List<string> GetuPNSuffixes()
{
    //add root domain
    List<string> suffixList = new List<string>();
    suffixList.Add(Domain.GetCurrentDomain().Name);

    //get the list of alternate domains
    DirectoryEntry rootDSE = new DirectoryEntry(@"LDAP://RootDSE");
    string context = rootDSE.Properties["configurationNamingContext"].Value.ToString();
    DirectoryEntry partition = new DirectoryEntry(@"LDAP://CN=Partitions," + context);

    foreach (string suffix in partition.Properties["uPNSuffixes"])
    {
        suffixList.Add(suffix);
    }

    return suffixList;
}
