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)
