[英]Impersonation and NetworkCredential
I need to pass a NetworkCredential
object with the credentials of the currently impersonated user to a web service from an asp.net application. 我需要将具有当前模拟用户凭据的
NetworkCredential
对象从asp.net应用程序传递给Web服务。
My code looks like this: 我的代码看起来像这样:
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.DefaultNetworkCredentials
should give the credentials of the currently impersonated user, but it is not the case. 我已经了解
CredentialCache.DefaultNetworkCredentials
应该提供当前模拟用户的凭据,但事实并非如此。
The log messages I get are 我得到的日志消息是
WindowsIdentity = TESTDOMAIN\TESTUSER
DefaultNetworkCredentials =
Am I doing something wrong? 难道我做错了什么? If so, how do you get a NetworkCredential object for the currently impersonated user?
如果是这样,您如何获得当前模拟用户的NetworkCredential对象?
A somewhat lengthy article in MSDN explaining the options to obtain network credentials in ASP: MSDN中有点冗长的文章,解释了在ASP中获取网络凭据的选项:

使用asp.net模拟用户( Current.User.Identity
)进行网络身份验证是不可能的,它只能在本地运行。
