c# - 向 ADFS 进行身份验证时出现 "An error occurred when verifying security for the message"异常

Question

正如我在 another question 中所描述的那样我构建了一个 Web 服务，该服务将使用用户名/密码并基于这些凭据在 ADFS2 中对用户(移动应用程序)进行身份验证。我的 Web 服务在 ADFS 上配置为 RP。 ADFS 颁发 SAML 2.0 token 。

这是网络方法的代码:

public class MobileAuthService : IMobileAuthService
{
    private const string adfsBaseAddress = @"https://<my_adfs_hostname>/adfs/services/";
    private const string endpointSuffix = @"trust/13/issuedtokenmixedsymmetricbasic256";

    public string AuthenticateUser(string username, string password)
    {
        var binding = new WS2007HttpBinding(SecurityMode.Message);
        binding.Security.Message.EstablishSecurityContext = false;
        binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
        binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
        binding.Security.Mode = SecurityMode.TransportWithMessageCredential;

        var trustChannelFactory = new WSTrustChannelFactory(binding, new EndpointAddress(adfsBaseAddress + endpointSuffix))
                                        {
                                            TrustVersion = TrustVersion.WSTrust13
                                        };
        trustChannelFactory.Credentials.UserName.UserName = username;
        trustChannelFactory.Credentials.UserName.Password = password;

        var tokenClient = (WSTrustChannel)trustChannelFactory.CreateChannel();

        var rst = new RequestSecurityToken(RequestTypes.Issue, KeyTypes.Symmetric);
        var token = tokenClient.Issue(rst);

        // do some token-related stuff

        return token.Id;
    }
}

当我尝试运行它时(来自浏览器的 GET 调用，因为它为此端点配置了 Web http 绑定(bind))我得到以下异常:

System.ServiceModel.Security.MessageSecurityException - "An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail."

有内部异常:

System.ServiceModel.FaultException - "An error occurred when verifying security for the message."

我猜这与响应签名或证书有关，但我不知道如何克服这个问题，因为我是 WIF 的新手。

我已经设法(部分)解决了这个问题。我在我的代码中做了一些改动，但问题似乎与以下内容有关:

• STS 端点 - 应该是 /trust/13/usernamemixed 用于这种类型的身份验证
• RST key 类型 - 当我设置它时 Bearer 它开始返回 SAML token

这是我的最新版本:

public class MobileAuthService : IMobileAuthService
{
    private const string stsEndpointAddress = @"https://<my_adfs_hostname>/adfs/services/trust/13/usernamemixed";

    private const string relyingPartyAddress =
        "https://<my_service_addr>/Auth.svc";

    public string AuthenticateUser(string username, string password)
    {
        var binding = new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential)
            {
                ClientCredentialType = HttpClientCredentialType.None
            };

        var trustChannelFactory = new WSTrustChannelFactory(binding, new EndpointAddress(stsEndpointAddress))
                                        {
                                            TrustVersion = TrustVersion.WSTrust13
                                        };

        var channelCredentials = trustChannelFactory.Credentials;
        channelCredentials.UserName.UserName = username;
        channelCredentials.UserName.Password = password;
        channelCredentials.SupportInteractive = false;

        var tokenClient = (WSTrustChannel)trustChannelFactory.CreateChannel();

        var rst = new RequestSecurityToken(RequestTypes.Issue, KeyTypes.Bearer)
            {
                AppliesTo = new EndpointReference(relyingPartyAddress),
                ReplyTo = relyingPartyAddress,
                TokenType = "http://docs.oasis-open.org/wss/oasis-wss-saml-token-profile-1.1#SAMLV2.0"
            };

        // to some token-related stuff (like transformations etc...)
    }
}

我希望这对遇到类似问题的人有所帮助。
