I am trying to develop a Solution which has both a Web and Winforms Client. There are requirements for SSO. I must support a variety of Authentication Sources. I have written my own STS to convert tokens from a variety of sources into an Authorisation token with claims aceptable to my application.
My STScan alsoprovide AuthenticationWindows Users and Custom Username password by providing a Passive and Active (WsTrust) endpoints.

I have developed my Web Login which delegates Authentication to one ofmy supportedAuthentication Providers, Including LiveID.
I have developed my Winforms Login which makes a WSTrust call to my STS for windows or custom Authentication. What I want to do is Usethis SAME login and a consistent/generic (WSTrust) method of Authenticating against LiveID. TheWILD SDK 1.0has its own UI, Ihave tried the Live frame work SDK, but thisis not consistent / generic and Iget a TokenString back which I am imagining will require a lot of effort to convert into a Token I can passon to my STS for Authorisation.

Can someoneadvise, If a Simple WSTrust endpoint forLive exists and is working.
If what I need is supported or ever going to be
If anyone has had any success.
If the Geneva Code samples can cover this scenario

i have tried the following threads

http://social.msdn.microsoft.com/Forums/en-US/Geneva/thread/965ff61e-bb5c-4c47-a429-377e7cae617b

and in particualr the code sample at ....
http://www.zamd.net/PermaLink,guid,734232f7-51ca-49b0-9d2f-4981c958565f.aspx

which is exactly what I want, but fails to work with my Valid Win Live credentials .. extremely useful error "Invalid Request".

Thanks in advance
