Authentication in SharePoint 2013

This question comes up a lot from companies moving from SharePoint 2010 to SharePoint 2013 – just how does authentication work in SharePoint 2013?

-In the 2013 version – user authentication remains the same with standard sites.

-When calling a web app – the authentication happens internally.

-Internal authentication happens when calling the web app.

-External authentication – is utilized from the remote web site/application.

-To establish an app identity claims based authentication must occur.

-Incoming calls must use CSOM/REST end – points.

-Essentially the authentication is the same except that calls to the web application are authenticated with both user identity and app identity.

-Application pages are deployed once per farm

-Application pages are accessed via _layouts virtual directory

-Application pages are compiled via ASP.NET

-Application pages don’t support user customization

-Application pages are added via farm solutions

-Application pages are compiled into a single .dll and loaded for each web application
