• Post it to https://login.microsoftonline.com/login.srf (body should be wa=wsignin1.0, wresult=…token… 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.
