不工作的NetworkCredential UseDefaultCredentials [英] NetworkCredential UseDefaultCredentials not working

问题描述

我们写了一个很长的代码返回到调用服务使用域凭据。现在域改变，计划使用默认的Windows帐户

所以我想重置网络凭据通过配置一个ASMX web服务。
我创建了一个SoapExtentsion类，并试图覆盖甚至有它执行就行了。但它从来没有被应用，并始终低于现有代码的胜利

实际代码

 的EmployeeService PRXY =新的EmployeeService（）; 
 prxy.Credentials =新System.Net.NetworkCredential（我的帐户，PWD，MYDOMAIN）; 
 //prxy.UseDefaultCredentials = TRUE; //它的工作原理，但我们不希望更改代码
 prxy.GetEmployee（EMPID）; 
  

新代码/配置变化仅

计划通过额外的DLL和配置的变化注入。所以不需要在原有的上面的代码更改代码/禁止现在

 公共类WindowsDefCredSoapExtn：的SoapExtension

任何一个知道如何动态地更改通过配置用于ASMX服务网络凭据？

更新：

在调试，我可以看到网络凭据复位。 。但不知何故，调用请求时发送到服务器

 的EmployeeService PRXY =新的EmployeeService（）; 
 prxy.Credentials =新System.Net.NetworkCredential（我的帐户，PWD，MYDOMAIN）; 
 //调试时，prxy.UseDefaultCredentials =假这里
 //我的SOAP扩展会被执行并且重置凭证。 
 prxy.GetEmployee（EMPID）; 
 //调试时，prxy.UseDefaultCredentials =真在这里
 //同时调试prxy.Credentials为空在这里。 
  

输出窗口：

请参阅最后一行AcquireCredentialsHandle通过的authData 。这在 prxy.Credentials =设置凭据新System.Net.NetworkCredential（我的帐户，PWD，MYDOMAIN）正在使用，即使我的服务扩展复位。

更新2

我只是做了测试功能更改代码及以下的差异socket通信

  AcquireDefaultCredential（包= NTLM，意图=出站）
  

VS

  AcquireCredentialsHandle（包= NTLM，意图=出站，的authData = MyDomain\MyAccount）
  

解决方案

如果我理解你。正确的话，我想你需要添加一个键AppSetting下的配置文件您的账户，用户名和密码。

 <的appSettings> 
<添加键=您的域VALUE =yourAccount/> 
<添加键=用户名值=yourAccount/> 
<添加键=密码值=yourAccount/> 
< /的appSettings> 
  

在，在你的代码，

 的EmployeeService PRXY =新的EmployeeService（）; 
 prxy.Credentials =新System.Net.NetworkCredential（System.Configuration.ConfigurationManager.AppSettings [用户名]。的ToString（），System.Configuration.ConfigurationManager.AppSettings [密码]的ToString（）， System.Configuration.ConfigurationManager.AppSettings [您的域]的ToString（））。 
 //调试时，prxy.UseDefaultCredentials =假这里
 //我的SOAP扩展会被执行并且重置凭证。 
 prxy.GetEmployee（EMPID）; 
  

We wrote a code long back to call a service with domain credentials. Now domains are changed and planning to use default Windows Account

So I am trying to reset Network credentials for a asmx webservice via config. I created a SoapExtentsion class and trying to override there even it executes the line. But it never gets applied and always the below existing code win

Actual Code

EmployeeService prxy = new EmployeeService();
prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain");
 //prxy.UseDefaultCredentials = true;// It works but we dont want code change
prxy.GetEmployee(empId);

New Code / Config Change only

Planning to inject via additional dll and config changes. So the code change in original above code is not required/prohibited now

public class WindowsDefCredSoapExtn : SoapExtension
{
    public override object GetInitializer(Type serviceType)
    {
        return "";
    }

    public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
    {
        return "";
    }

    public override void Initialize(object initializer)
    {
        //throw new NotImplementedException();
    }

    public override void ProcessMessage(SoapMessage message)
    {

      if (message is SoapClientMessage)
          {
          if (message.Stage == SoapMessageStage.BeforeSerialize)
              {                             
              ((SoapClientMessage)message).Client.Credentials=null;
              (((SoapClientMessage)message)).Client.UseDefaultCredentials = true;

              }
          }                

        }

    }
}


 <system.web>
    <webServices>
      <soapExtensionTypes>
        <add type="MyAssembly.WindowsDefCredSoapExtn, MyAssembly" priority="1" group="Low"/>
      </soapExtensionTypes>
    </webServices>
  </system.web>

Any one know how to dynamically change the Network Credentials used for a ASMX service via config?

UPDATE:

While debug, I could see the network credentials are reset. But somehow it sends to server when invoking the request.

EmployeeService prxy = new EmployeeService();
prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain");
 //while debug, prxy.UseDefaultCredentials= false here
//My soap extension gets executed and resets credentials.
prxy.GetEmployee(empId);
 //while debug, prxy.UseDefaultCredentials= true here
 //while debug prxy.Credentials are null here. 

Output Window:

See the last line AcquireCredentialsHandle passes authdata. The credentials which set in prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain") being used even though my service extension reset.

UPDATE 2

I just did a code change for tesing and below is difference in the socket communication

AcquireDefaultCredential(package = NTLM, intent  = Outbound) 

Vs

AcquireCredentialsHandle(package  = NTLM, intent   = Outbound, authdata = MyDomain\MyAccount)

解决方案

If I understood you correctly then I think you need to add a keys for your Account,User Name and Password under AppSetting in config file.

  <appSettings>
    <add key="YourDomain" value="yourAccount"/>
<add key="UserName" value="yourAccount"/>
<add key="Password" value="yourAccount"/>
  </appSettings>

After that in your code,

EmployeeService prxy = new EmployeeService();
prxy.Credentials = new System.Net.NetworkCredential(System.Configuration.ConfigurationManager.AppSettings["UserName"].ToString(), System.Configuration.ConfigurationManager.AppSettings["Password"].ToString(), "System.Configuration.ConfigurationManager.AppSettings["YourDomain"].ToString()");
 //while debug, prxy.UseDefaultCredentials= false here
//My soap extension gets executed and resets credentials.
prxy.GetEmployee(empId);
