Connected App?
When do you need to setup a connected app configuration? We have a native iPad app that uses Oath2 and the native SF login page without needing a Connected app config in this org. When is this required?
You need a Connected App if you're using OAuth to authenticate a mobile client application. If the pieces of your app that connect to Salesforce are limited to web-based functionality/pages, then you could probably get by without one. If you need granularity of permissions controls, the ability to have long-lived authentication management, or make REST API calls from the native layer, you're going to want an OAuth "app", which means configuring a Connected App.
