c# - Claim auth from ADFS

I try to connect to a SharePoint Online instance via a WPF-Application. I have found this article[1] that discribes a possible solution but the problem is that the specific instance has a Active Directory Federation Services (ADFS) infront and I don't know how to get the auth-token. (I can't create a certificate for my application to authentificate against the adfs.)
Anyone who have already done this and can support me with some code snippets?

I've played with Fiddler. Basically the flow goes like this:

• Get a SAML token from ADFS
• Post it to https://login.microsoftonline.com/login.srf (body should be wa=wsignin1.0, wresult=<requestsecuritytokenresponse>…token…</rstr> and wctx=MEST=0&LoginOptions=2&wa=wsignin1%2E0&rpsnv=2&ct=1343219880&rver=6%2E1%2E6206%2E0&wp=MBI&wreply=https%3A%2F%2Fspirit365%2Esharepoint%2Ecom%2F%5Fforms%2Fdefault%2Easpx&id=500046&cbcxt=mai&wlidp=1&guest=1&vv=910&mkt=EN-US&lc=1033&bk=1343219930
• Capture the input hidden named "t" from the Form
• POST that "t" to /_layouts/Authenticate.aspx. That should give you the FedAuth and rtFa cookie.

From that point this is the same as the code here: http://www.wictorwilen.se/Post/How-to-do-active-authentication-to-Office-365-and-SharePoint-Online.aspx

I have found the solution and made a post about it. I also put it on github. You can find my blog post along with the github link at my blog:http://jwillmer.de/blog/2013/01/04/sharepoint-online-with-adfs-authentication/
I hope this helps you as much as it helped me :-)
