I'm Samuel Devasahayam, a lead Program Manager in the Active Directory team at Microsoft. I've been with the Active Directory team since 1998 when I joined after grad school. I drive Active Directory Federation Services as well as some of our recent onboarding efforts for Azure Active Directory/Office 365 through Azure AD Connect.
Of late, I find myself answering numerous questions both to Microsoft customers as well as internal Microsoft employees on things surrounding ADFS or Office 365/Azure AD authentication. This blog will primarily focus on making these questions (and their answers of course :)) more accessible and public.
Please use feedback/comments for any additional questions you would like answered around ADFS.
