如何连接到MVC 5中的本地LDAP服务器？ [英] How to connect to local LDAP server in MVC 5 ?

问题描述

你好，

我正在尝试连接到我拥有的本地LDAP服务器使用Apache Directory Studio进行设置。我正在使用Visual Studio 2015企业更新2和MVC 5.

以下是我使用的两种方法：

  public void ldap（）
 {
 
 try 
 {
 DirectoryEntry entry =新迪rectoryEntry（QUOT; LDAP：//本地主机：10389"）; 
 DirectorySearcher mySearcher = new DirectorySearcher（entry）; 
 
 var result = mySearcher.FindOne（）; 
 
} 
 catch（System.Runtime.InteropServices.COMException）
 {
 System.Runtime.InteropServices.COMException异常= new System.Runtime.InteropServices.COMException（ ）; 
 Console.WriteLine（exception）; 
} 
 catch（InvalidOperationException）
 {
 InvalidOperationException InvOpEx = new InvalidOperationException（）; 
 Console.WriteLine（InvOpEx.Message）; 
} 
 catch（NotSupportedException）
 {
 NotSupportedException NotSuppEx = new NotSupportedException（）; 
 Console.WriteLine（NotSuppEx.Message）; 
} 
}  

执行var result = mySearcher.FindOne（）后，执行System.Runtime。 System.DirectoryServices.dll中出现"InteropServices.COMException"，表示在调用COM-Component时传递了HRESULT E_FAIL错误。

我不知道这意味着什么使用Google找不到有用的东西。

2nd approach：

  try 
 {
 LdapConnection ldapConnection = new LdapConnection（" LDAP：// localhost：10389"）; 
 
 var networkCredential = new NetworkCredential（" ; cbrunato"，" c2VjcmV0"，" dc = example，dc = com"）; 
 ldapConnection.SessionOptions.SecureSocketLayer = true; 
 ldapConnection.SessionOptions.VerifyServerCertificate + = delegate {return true;} ; 
 ldapConnection.AuthType = AuthType.Negotiate; 
 ldapConnection.Bind（networkCredential）; 
} 
 catch（例外e）
 {
 Console.WriteLine （e.Message）; 
}  

执行ldapConnection.Bind（networkCredential）后，我收到错误消息"LDAP服务器不可用"。

当我停止ldap服务器并运行程序时，我得到相同的错误，所以我想我没有得到与我的ldap服务器的连接两种方法，但我没有提示为什么。

我非常感谢任何帮助。

解决方案

执行var result = mySearcher.FindOne（）后，System.DirectoryServices.dll中出现System.Runtime.InteropServices.COMException'，表示在调用COM组件时传递了HRESULT E_FAIL错误。

我不知道这意味着什么并且没有找到有用的东西。

这是事情的运作方式  ;在.NET之前，MS Windows O / S平台上的许多解决方案仍然基于COM解决方案。

Hello,

I´m trying to connect to an local LDAP server which i have set up using Apache Directory Studio. I´m using Visual Studio 2015 enterprise update 2 and MVC 5.

These are the two approaches I´m working with:

 public void ldap()
    {

        try
        {
            DirectoryEntry entry = new DirectoryEntry("LDAP://localhost:10389");
            DirectorySearcher mySearcher = new DirectorySearcher(entry);

            var result = mySearcher.FindOne();

        }
        catch (System.Runtime.InteropServices.COMException)
        {
            System.Runtime.InteropServices.COMException exception = new System.Runtime.InteropServices.COMException();
            Console.WriteLine(exception);
        }
        catch (InvalidOperationException)
        {
            InvalidOperationException InvOpEx = new InvalidOperationException();
            Console.WriteLine(InvOpEx.Message);
        }
        catch (NotSupportedException)
        {
            NotSupportedException NotSuppEx = new NotSupportedException();
            Console.WriteLine(NotSuppEx.Message);
        }
     }

After var result = mySearcher.FindOne() is executed, an System.Runtime.InteropServices.COMException' in System.DirectoryServices.dll occures, stating that an HRESULT E_FAIL-error was passed when calling a COM-Component.

I have no idea what that means and didn´t find something helpful using Google.

2nd approach:

try
        {
            LdapConnection ldapConnection = new LdapConnection("LDAP://localhost:10389");

            var networkCredential = new NetworkCredential("cbrunato", "c2VjcmV0", "dc=example,dc=com");
            ldapConnection.SessionOptions.SecureSocketLayer = true;
            ldapConnection.SessionOptions.VerifyServerCertificate += delegate { return true; };
            ldapConnection.AuthType = AuthType.Negotiate;
            ldapConnection.Bind(networkCredential);
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }

After ldapConnection.Bind(networkCredential) is executed, i get the error message "LDAP server is not available".

When i stop the ldap Server and run the program i get the same errors, so i guess i don´t get a connection to my ldap server with both approaches, but i have no clue why.

I´m very thankful for any help.

It's how things worked before .NET and many solutions on the MS Windows O/S platform are still based on COM solutions.
