Hi,
Securing APIs using Web APIs with Windows Azure ADversus OAuth 2.0. I have implemented and secured my cloud service APIs using Windows Azure AD (without Oauth) as a proof of concept. I used the link titled "Secure ASP.NET Web API with Windows Azure AD" (http://weblogs.asp.net/jdanforth/secure-asp-net-web-api-with-windows-azure-ad)
I am now reading another article titled "Microsoft Azure RESTAPI+ OAuth 2.0" (https://ahmetalpbalkan.com/blog/azure-rest-api-with-oauth2/)
My questions are
1) What are the differences (pros / cons )between securing Azure REST API using Windows Azure AD versus OAuth 2.0
2) Using the Windows Azure AD approach, if I wanted external users to use my APIs,
would they need to register a client app using the Windows Azure management portal?
Thanks
