从STS请求securitytoken并将其发布到我的网站

Question

我的网站实现了基于AD FS的认证。现在我需要通过客户端以编程方式访问我的网站。我的客户端应该使用当前登录的用户上下文从ADFS服务器请求安全令牌。我已经能够成功地使用客户端的用户名和密码从adfs/services/trust/13/usernamemixed端点请求安全令牌，并将其发布到我的网站。

不适合我的是使用DefaultNetworkCredentials从adfs/services/trust/13/windowsmixed端点请求相同的令牌。我得到错误The HTTP request was forbidden with client authentication scheme 'Anonymous'.。我正在使用Microsoft.IdentityModel SDK(而不是。net 4.5中的System.IdentityModel)。

这是我的一段代码。

  factory = new MSWSTrustChannelFactory(
  new Microsoft.IdentityModel.Protocols.WSTrust.Bindings.WindowsWSTrustBinding(SecurityMode.TransportWithMessageCredential),
                    stsUrl);
  factory.TrustVersion = TrustVersion.WSTrust13;
  factory.Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
  var rst = new RequestSecurityToken
  {
      RequestType = RequestTypes.Issue,
      AppliesTo = new EndpointAddress(realm),
      KeyType = KeyTypes.Bearer,
      RequestDisplayToken = true
  };
  MSIWSTrustChannelContract channel = factory.CreateChannel();
  RequestSecurityTokenResponse rstr;
  SecurityToken token = channel.Issue(rst, out rstr);

我对ADFS服务器没有任何控制，也无法从那里调试出什么问题。无论我能做什么，都只能从客户端着手。任何想法是什么是错的，我的代码上面?如有任何帮助或指点，不胜感激。

我认为您需要将消息安全的establishSecurityContext设置为FALSE
binding.Security.Message.EstablishSecurityContext = false;

下面的代码为我工作。

            WS2007HttpBinding binding = new WS2007HttpBinding(SecurityMode.TransportWithMessageCredential);
            binding.Security.Message.EstablishSecurityContext = false;               
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
            if (isWindowsUser)
            {
                binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;
                ep = new EndpointAddress("https://abc.com/adfs/services/trust/13/windowsmixed");                    
            }
            else
            {
                binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
                ep = new EndpointAddress("https://abc.com/adfs/services/trust/13/usernamemixed");                    
            }
            factory = new WSTrustChannelFactory(binding, ep);
            factory.TrustVersion = TrustVersion.WSTrust13;
                factory.Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;                     

            var rst = new RequestSecurityToken
            {
                RequestType = RequestTypes.Issue,
                AppliesTo = new EndpointReference("urn:adfsmonitor"),
                KeyType = KeyTypes.Bearer,
            };
            IWSTrustChannelContract channel = factory.CreateChannel();
            GenericXmlSecurityToken genericToken = channel.Issue(rst)
             as GenericXmlSecurityToken;
            return genericToken.TokenXml.InnerXml.ToString();
