It's me, Brandon Werner, back with you again!.As part of our best practice of protecting customers data world wide, Azure Active Directory periodically rolls the certificates of the service. The Azure Active Directory authentication service will be performing a certificate rollover on 5/23. If you followed the development guidelines outlined below, you should experience no impact. We've included information below so you can review your applications and ensure they are following these best practices.
We do not expect any impact for:
Any application which follows the best practices outlined here: https://msdn.microsoft.com/en-us/library/azure/dn641920.aspx
