主机上配置的身份验证方案（'Basic'）不允许在绑定'BasicHttpBinding'上配置的身份验证方案

Question

错误

  

主机上配置的身份验证方案（“基本”）不会   允许在绑定'BasicHttpBinding'上配置的那些   （'匿名'）。请确保将SecurityMode设置为   运输或运输保险仅限。另外，这可能是   通过更改此应用程序的身份验证方案来解决   通过IIS管理工具，通过   ServiceHost.Authentication.AuthenticationSchemes属性，在   应用程序配置文件在   element，通过更新绑定上的ClientCredentialType属性，   或者通过调整AuthenticationScheme属性   HttpTransportBindingElement。

你知道web.config中的问题在哪里吗？我尝试使用Windows凭据通过基本身份验证登录到WCF。
