[ Programtically sign into Office 365 OWA using ADFS/MSOSTS tokens ]

Trying to programatically sign into OWA using ADFS 2.0. The domain is federated and sign in works as expected (redirect to https://myadfs.server/adfs/ls/?blabla) from https://login.microsoftonline.com/.

Instead of using the adfs redirect, I have created my own sign in page using the code sample here.

But the code is for SharePoint. I need OWA. I guess main thing I need to change is the service URL for Office 365 OWA that will return authorization cookies. The code uses https://mysharepoint.server/_forms/default.aspx?wa=wsignin1.0 to get the auth cookies

Does anyone know what is the equivalent url for OWA? Or any code sample?

A different approach can be used to sign into O365. The main thing is I'm not ONLY trying to sign into O365. I need to obtain the logon token, and present a "dashboard" to the user which allows them to chose which service they want to use this token (or logged in Identity) for, of which Office 365 is ONE of the services.
