Im have implemented the Windows Live Id authentication to my app. It works pretty well, but now I would like to authenticate my company office365 with a similuar solution. I have searched through google but I could not find a way to do this. There is only four brandings: Messenger, Microsoft Account, SkyDrive and Outlook.
Has anyone done something similuar, is this even possible?
It's is not possible to use your office 365 as single sign on. You must use your Microsoft Account, in this case your Windows Live Id. This guide will show you how.
You can how ever make your own authentication service by puting your Active Directory in Windows Azure if you want to use that instead. This guide show you how to set up the a Active Directory forest in Windows Azure.
