If you implement the custom security extensions and configure to use forms authentication in Microsoft SQL Server 2016 Reporting Services (SSRS 2016), you will find that the Report Server web portal URL is working fine. However, the Report Server Web service URL is getting truncated with a dropped query string when it redirects to the authentication page for unauthenticated users which makes the user authentication to fail.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
