当我使用DirectorySearcher调用find.One时，错误消息是什么意思 [英] What is the error message meant when I call find.One using DirectorySearcher

问题描述

我是编写代码来访问AD的新手。我按照AD结构设置：

DC = UAT，DC = COM

OU = ORG

OU =用户和组

OU =系统

OU =团体

CN =管理员

OU =用户

OU =测试

OU =团体

OU =用户

CN = test01

CN = test02



我写了以下示例代码来搜索用户test02，但收到错误：

使用System; 
使用System.IO;使用System.DirectoryServices 
; 
使用System.Configuration; 
 try 
 {
 DirectoryEntry userEntry = new DirectoryEntry（LDAP：// SERVERIP / OU = ORG，DC = UAT，DC = COM，用户，密码）; 
 DirectorySearcher search = new DirectorySearcher（userEntry）; 
 
 search.SearchScope = SearchScope.Subtree 
 
 //搜索用户test02 
 search.Filter =（&（objectClass = user）（objectCategory = Person） （sAMAccountName赋= test02））; 
 
 SearchResult result = search.FindOne（）; //在此行失败，抛出异常
 
 if（result == null）
 Console.WriteLine（没有要显示的结果）; 
 else 
 Console.WriteLine（Found result）; 
} 
 catch（exception ex）
 {
 Console.WriteLine（Error：+ ex.Message）; 
 Console.WriteLine（Trece：+ ex.StackTrace）; 
} 

错误：配置系统无法初始化< br /> 
 Trece ：在System.Configuration.ClientConfigurationSystem上的System.Configuration.ClientConfigurationSystem.EnsureInit（String configKey）< br /> 
，System.Configuration.ClientConfigurationSystem.PrepareClientConfigSystem（String sectionName）< br /> 
。在System.Configuration.PrivilegedConfigurationManager的System.Configuration.ConfigurationManager.GetSection（String sectionName）< br /> 
的System.Configuration.Internal.IInternalConfigSystem.GetSection（String sectionName）< br /> 
。 System.DirectoryServices.SearchResultCollection.ResultsEnumerator..ctor（SearchResultCollection结果，String parentUserName，String parentPassword，AuthenticationTypes parentAuthenticationType）中的GetSection（String sectionName）< br /> 
< br /> 
 at System。 System.DirectoryServices上的DirectoryServices.SearchResultCollection.GetEnumerator（）< br /> 
 .DirectorySearcher.FindOne（）< br /> 

你能帮忙并告知我做错了吗？



非常感谢！

我发现我的配置文件错误。谢谢！

Hi,

I'm new in writing code to access AD. I setup following AD structue:
DC=UAT,DC=COM
OU=ORG
OU=Users and Groups
OU=System
OU=Groups
CN=Admins
OU=Users
OU=Test
OU=Groups
OU=Users
CN=test01
CN=test02

I wrote the following sample codes to search for the user test02, but got error:

using System;
using System.IO;
using System.DirectoryServices;
using System.Configuration;
try
{
    DirectoryEntry userEntry = new DirectoryEntry("LDAP://SERVERIP/OU=ORG,DC=UAT,DC=COM", user, password); 
    DirectorySearcher search = new DirectorySearcher(userEntry);
             
    search.SearchScope = SearchScope.Subtree

    // Search user test02           
    search.Filter = "(&(objectClass=user)(objectCategory=Person)(sAMAccountName=test02))";               
             
    SearchResult result = search.FindOne();   // Failed at this line,  throw exception 

    if (result == null)
       Console.WriteLine("There is no results to display");
    else
       Console.WriteLine("Found result ");                
}
catch (Exception ex)
{
    Console.WriteLine("Error: " + ex.Message);
    Console.WriteLine("Trece: " + ex.StackTrace);
}

Error:  Configuration system failed to initialize<br />
Trece:    at  System.Configuration.ClientConfigurationSystem.EnsureInit(String configKey)<br />
   at System.Configuration.ClientConfigurationSystem.PrepareClientConfigSystem(String sectionName)<br />
   at System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection(String sectionName)<br />
   at System.Configuration.ConfigurationManager.GetSection(String sectionName)<br />

   at System.DirectoryServices.SearchResultCollection.GetEnumerator()<br />
   at System.DirectoryServices.DirectorySearcher.FindOne()<br />

Could you help and advise what I did wrong?

Thank you very much!
