通过负载均衡器连接到同一服务器的 WCF 服务时出现身份验证错误

Question

我有 2 台服务器。每台服务器都安装了一个 WCF 服务。客户端通过负载均衡器连接到服务。负载均衡器将请求分发到这 2 台服务器。当负载均衡器将请求重定向到客户端所在的同一台服务器时，会发生安全错误。当负载均衡器将请求重定向到另一台服务器时，一切正常。错误：

System.ServiceModel.Security.SecurityNegotiationException: The server has rejected the client credentials.
 ---> System.Security.Authentication.InvalidCredentialException: The server has rejected the client credentials.
