我有一个问题,我从ISS连接到WCF服务,它传递的是IIS应用程序池凭据,而不是我的Windows凭据。当我通过在VS中点击F5在本地运行网站时,它会传递我的Windows凭据,这就是我想要的。
我的网站设置为使用Windows身份验证,匿名身份验证已关闭。
我可以在Windows事件查看器中看到它没有使用Kerberos连接到IIS所在的框,它正在使用NTLM。但我可以看到它使用Kerberos时从IIS到我的WCF服务使用:
OperationContext.Current.ServiceSecurityContext.PrimaryIdentity.AuthenticationType.ToString()
我认为在连接到IIS框时应该使用Kerberos所以我们会欣赏那些想法吗?
框和用户设置为允许委派,我已在我的
上启用NETTCP通信等这是我的主机配置,它使用与IIS服务器相同的服务器上的控制台应用程序托管:

这是所谓的服务方法:
[OperationBehavior(Impersonation = ImpersonationOption.Allowed)]
public string PrintMessage(string msg)
{
Console.WriteLine(DateTime.Now.ToString());
WindowsIdentity callerWindowsIdentity = ServiceSecurityContext.Current.WindowsIdentity;
Console.WriteLine("AuthenticationType: " + OperationContext.Current.ServiceSecurityContext.PrimaryIdentity.AuthenticationType.ToString());
Console.WriteLine("WindowsIdentity.GetCurrent(): {0}", WindowsIdentity.GetCurrent().Name);
using (ServiceSecurityContext.Current.WindowsIdentity.Impersonate())
{
Console.WriteLine("WindowsIdentity.GetCurrent(): {0}", WindowsIdentity.GetCurrent().Name);
}
Console.WriteLine("Method called successfully!");
}

听起来像Double Hop Problem的情况。在大多数情况下,服务器无法将通过网络接收的凭据模拟传递给其他主机。
这是一个blog post更详细地描述这种现象。

确保指定
<system.web>
<identity impersonate="true" />
<authentication mode="Windows" />
<authorization>
<deny users="?" />
</authorization>
</system.web>
这可确保不允许匿名登录。
此外,如果要将您的信用卡传递给WCF服务,则需要使用委派。在您的网站web.config中创建一个行为,如下所示:
<behaviors>
<endpointBehaviors>
<behavior name="DelegationBehavior">
<callbackDebug includeExceptionDetailInFaults="true" />
<clientCredentials>
<windows allowedImpersonationLevel="Delegation" />
</clientCredentials>
</behavior>
</endpointBehaviors>
</behaviors>
并通过behaviorConfiguration="DelegationBehavior"
在您的终端中使用它。
如果这不起作用,请尝试将<serviceAuthenticationManager authenticationSchemes="IntegratedWindowsAuthentication" />
添加到WCF web.config中的<serviceBehavior>
- 标记。
不要忘记用以下方法装饰你的WCF方法:
[OperationBehavior(Impersonation = ImpersonationOption.Required)]
或者,您可以通过<serviceBehavior>
中的其他标记模拟每次通话:
<serviceAuthorization impersonateCallerForAllOperations="true" />
