When you use custom authentication in Microsoft SQL Server 2014 or 2016 Reporting Services (SSRS), you experience a System.NullReferenceException error when you render reports, and you receive an error message that resembles the following in the Reporting Services log:

See the error log for more details. ---> System.NullReferenceException: Object reference not set to an instance of an object.
