Live ID Authentication for Rich Clients

Posted by zamd on March 18, 2009


Disclaimer: Please note following approach works but is totally unsupported.

Active version of Live ID STS is available at: https://dev.login.live.com/wstlogin.srf and we can get a SAML token by using standard WS-Security username token as input.

 

            var issuer = https://dev.login.live.com/wstlogin.srf;

            var binding = new WSHttpBinding();

            binding.Security.Mode = SecurityMode.TransportWithMessageCredential;

            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

            binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;

            binding.Security.Message.EstablishSecurityContext = false;

            binding.Security.Message.NegotiateServiceCredential = false;

 

 

            WSTrustClient client = new WSTrustClient(binding, new EndpointAddress(issuer),

                TrustVersion.WSTrustFeb2005, new ClientCredentials());

            client.ClientCredentials.UserName.UserName = zamd@liveid.com;

            client.ClientCredentials.UserName.Password = “password “;

 

            var rst = new RequestSecurityToken(RequestTypeConstants.Issue);

            rst.AppliesTo = new EndpointAddress(http://zamd.net);

 

            RequestSecurityTokenResponse rstr;

            var token = client.Issue(rst, out rstr) as GenericXmlSecurityToken;

    I’m attempting to do the same thing using newer versions of WIF but my request fails with “Invalid Request”. Here is my code:

    // Binding used to communicate with the Security Token Service (STS).
    UserNameWSTrustBinding binding = new UserNameWSTrustBinding(SecurityMode.Transport);

    // Address of the STS.
    EndpointAddress address = new EndpointAddress(“https://dev.login.live.com/wstlogin.srf”);

    // Channel factory used to submit credentials to STS.
    WSTrustChannelFactory channelFactory = new WSTrustChannelFactory(binding, address);
    channelFactory.TrustVersion = TrustVersion.WSTrustFeb2005;
    channelFactory.Credentials.UserName.UserName = username;
    channelFactory.Credentials.UserName.Password = password;

    WSTrustChannel channel = (WSTrustChannel)channelFactory.CreateChannel();

    // Build the Request for Security Token (RST).
    RequestSecurityToken rst = new RequestSecurityToken(RequestTypes.Issue);
    rst.AppliesTo = new EndpointAddress(appliesTo);
    rst.KeyType = keyType;

    // Perform operation to receive the Request for Security Token Response (RSTR).
    RequestSecurityTokenResponse rstr = null;
    token = channel.Issue(rst, out rstr);

    Could you please help me figure this out?
