Impersonation and NetworkCredential
提问by Paolo Tedesco
I need to pass a NetworkCredentialobject with the credentials of the currently impersonated user to a web service from an asp.net application.
My code looks like this:
我需要将NetworkCredential带有当前模拟用户凭据的对象从 asp.net 应用程序传递到 Web 服务。
我的代码如下所示：
WindowsIdentity windowsIdentity = HttpContext.Current.User.Identity as WindowsIdentity;
WindowsImpersonationContext context = windowsIdentity.Impersonate();
try {
var client = GetClient();
client.ClientCredentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
Log("WindowsIdentity = {0}", windowsIdentity.Name);
Log("DefaultNetworkCredentials = {0}", CredentialCache.DefaultNetworkCredentials.UserName);
client.DoSomething();
} finally {
context.Undo();
}
I had understood that CredentialCache.DefaultNetworkCredentialsshould give the credentials of the currently impersonated user, but it is not the case.
The log messages I get are
我知道CredentialCache.DefaultNetworkCredentials应该提供当前模拟用户的凭据，但事实并非如此。
我得到的日志消息是
WindowsIdentity = TESTDOMAIN\TESTUSER
DefaultNetworkCredentials =
Am I doing something wrong? If so, how do you get a NetworkCredential object for the currently impersonated user?
难道我做错了什么？如果是这样，您如何获得当前模拟用户的 NetworkCredential 对象？

It's not possible to use the asp.net impersonated user (Current.User.Identity) for network authentication, it only works locally.
无法使用 asp.net 模拟用户 ( Current.User.Identity) 进行网络身份验证，它只能在本地工作。
