问题描述

如果我将 .NET DirectoryEntry.Path 设置为:

If I set the .NET DirectoryEntry.Path to something like:

LDAP://CN=John Smith,OU=Group Name,DC=example,DC=com

一切都很好，我得到了我需要的 DirectoryEntry.但是，我不知道用户的真实通用名 (CN).我只知道他们的用户名John.Smith".

Everything works great, and I get the DirectoryEntry I need. However, I don't know the user's true Common Name (CN). I only know their username, "John.Smith".

那么，如何查询用户名?我尝试了以下所有没有成功:

So, how can I query the username? I have tried all the following without success:

LDAP://CN=John.Smith,OU=Group Name,DC=example,DC=com
LDAP://sAMAccountName=John.Smith,OU=Group Name,DC=example,DC=com
LDAP://userPrincipalName=John.Smith,OU=Group Name,DC=example,DC=com
LDAP://userPrincipalName=John.Smith@example.com,OU=Group Name,DC=example,DC=com
LDAP://uid=John.Smith,OU=Group Name,DC=example,DC=com
LDAP://o=John.Smith,OU=Group Name,DC=example,DC=com

推荐答案

您不能仅仅通过创建 LDAP 字符串进行查询 - 您需要为此使用代码.

You can't just query by means of creating an LDAP string - you'll need to use code for that.

类似:

DirectoryEntry deRoot = new DirectoryEntry("LDAP://yourserver/CN=Users,dc=YourCompany,dc=com");

DirectorySearcher dsFindUser = new DirectorySearcher(deRoot);
dsFindUser.SearchScope = SearchScope.SubTree;

dsFindUser.PropertiesToLoad.Add("sn"); // surname = last name
dsFindUser.PropertiesToLoad.Add("givenName"); // first name

dsFindUser.Filter = string.Format("(&(objectCategory=Person)(anr={0}))", yourUserName);

SearchResult rseult = dsFindUser.FindOne();

if(result != null)
{
   if(result.Properties["sn"] != null)
   {  
      string lastName = result.Properties["sn"][0].ToString();
   }

   if(result.Properties["givenName"] != null)
   {  
      string lastName = result.Properties["givenName"][0].ToString();
   }
}

System.DirectoryServices.DirectorySearcher<上的完整 MSDN 文档/a> 类可以在 MSDN 上找到 - 它有很多额外的属性和设置.

The full MSDN documentation on the System.DirectoryServices.DirectorySearcher class can be found on MSDN - it has lots of additional properties and settings.

如果您使用的是 .NET 3.5，那么使用强类型的例程库来处理用户和组会变得相当容易 - 请参阅此优秀的 有关该主题的 MSDN 文章 了解更多信息.

If you're on .NET 3.5, things have gotten quite a bit easier with a strongly-typed library of routines for handling users and groups - see this excellent MSDN article on the topic for more info.
