When building mobile business apps using Azure Mobile Services, accessing enterprise assets such as SharePoint is a common customer requirement. Customers expect to sign into the app using their domain identity, and authorize the app to access their calendar or document library. These scenarios are easy with Azure Active Directory and Mobile Services, which enable true integration by allowing multiple services to accept the same authentication token used by mobile apps.
This sample will show how to use the Active Directory Authentication Library (ADAL) in order to authenticate a mobile app user against Mobile Services and then reuse that access token in order to gain access to an O365 service. All in less than 15 minutes!
