示例

以下代码演示了创建此类实例的一种常见方法。

static EndpointIdentity CreateIdentity()
 {
     WindowsIdentity self = WindowsIdentity.GetCurrent();
     SecurityIdentifier sid = self.User;

     EndpointIdentity identity = null;

     if (sid.IsWellKnown(WellKnownSidType.LocalSystemSid) ||
         sid.IsWellKnown(WellKnownSidType.NetworkServiceSid) ||
         sid.IsWellKnown(WellKnownSidType.LocalServiceSid))
     {
         identity = EndpointIdentity.CreateSpnIdentity(
             string.Format(CultureInfo.InvariantCulture, "host/{0}", GetMachineName()));
     }
     else
     {
         // Need an UPN string here
         string domain = GetPrimaryDomain();
         if (domain != null)
         {
             string[] split = self.Name.Split('\\');
             if (split.Length == 2)
             {
                 identity = EndpointIdentity.CreateUpnIdentity(split[1] + "@" + domain);
             }
         }
     }

     return identity;
 }

Private Shared Function CreateIdentity() As EndpointIdentity
     Dim self As WindowsIdentity = WindowsIdentity.GetCurrent()
     Dim sid As SecurityIdentifier = self.User

     Dim identity As EndpointIdentity = Nothing

     If sid.IsWellKnown(WellKnownSidType.LocalSystemSid) OrElse sid.IsWellKnown(WellKnownSidType.NetworkServiceSid) OrElse sid.IsWellKnown(WellKnownSidType.LocalServiceSid) Then
         identity = EndpointIdentity.CreateSpnIdentity(String.Format(CultureInfo.InvariantCulture, "host/{0}", GetMachineName()))
     Else
         ' Need an UPN string here
         Dim domain As String = GetPrimaryDomain()
         If domain IsNot Nothing Then
             Dim split() As String = self.Name.Split("\"c)
             If split.Length = 2 Then
                 identity = EndpointIdentity.CreateUpnIdentity(split(1) & "@" & domain)
             End If
         End If
     End If

     Return identity
End Function

注解

SPN 是一个名称，客户端通过该名称唯一地标识服务实例。 如果在整个林的计算机上安装多个服务实例，则每个实例都必须有自己的 SPN。 如果客户端可能用于身份验证的多个名称，则给定的服务实例可以有多个 SPN。

当客户端想要连接到服务时，它会找到服务的实例，为该实例编写 SPN，并将标识设置为 a SpnEndpointIdentity。 将检查消息是否适用于该服务。

Kerberos 下使用的三种身份验证模式是：

• SSPINegotiate

• Kerberos

• KerberosOverTransport。
