How to Do the live id Silent Authentication by passing Client credentials as parameters

I have requirement to pass user name and password from my application Login page , once user provide user name and password i need to authenticate user using Active directory.

Please note: User name here is the Windows Live Id and Password is the Password for the live id account.

When i am using below code i am getting missing_federation_metadata_urlerror code for live id account but same is working fine for internal org id.

Code    publicstaticstring GetAuthenticationHeader(string tentant = "Common")

        {

           UserCredential uc =newUserCredential("Live Id","Password");

           AuthenticationResult result =null;

           var thread =newThread(() =>

            {

               try

                {

                   var context =newAuthenticationContext(string.Format("https://login.windows.net/{0}","Federation End Point"));

                    result = context.AcquireToken(

                        resource:ConfigurationManager.AppSettings["WindowsManagementUri"],

                        clientId:ConfigurationManager.AppSettings["AsaClientId"],

                        userCredential: uc);

                }

               catch (Exception threadEx)

                {

                   Console.WriteLine(threadEx.Message);

                }

            });

            thread.SetApartmentState(ApartmentState.STA);

            thread.Name ="AcquireThread";

            thread.Start();

            thread.Join();

           if (result !=null)

            {

               return result.AccessToken;

            }

           thrownewInvalidOperationException("test");

        }

Please Suggest.
