I understand ACS is being phased out in favor of WAAD. As I prepare to delve into Azure for the first time I have a few questions. I already have an Azure account (linked with my MSDN account).
Under ACS, I would create a namespace for my application, configure it with Idps and claims mapping. I would point my application (a RESTful API via WebAPI2) to the ACS federation endpoint for my namespace.
Under WAAD, I've seen where I can add my own application. When I create the new application, is this creating a tenant in my directory? I dont see where I can register my Idp's and configure the Idp's for my relying party. In addition to authenticating via social networks (like facebook/google/etc), I'm going to want to write a custom Idp to hit against my on-premesis user store. Is this possible in WAAD? Finally when creating the application (tenant) in WAAD, its prompting me for a Signon URL. Isn't WAAD supposed to manage the signon, the way it did under ACS? when I defended a website via ACS, the user was redirected to the ACS sign in page, where they could choose from a list of Idp's for login. Why then, under WAAD, do I, the app developer, need to code a sign on page? I'm pretty confused about this.
