I set up my Power BI reporting server as per the custom authentication steps mentioned in the git repository
https://github.com/microsoft/Reporting-Services/tree/master/CustomSecuritySample
Now after setup, I created a few users and am willing to access it from a web application(.net MVC). But I am continuously getting an error check the below screenshot.
The error I am getting is:-
After researching a lot, I figured out that Power Bi reporting server configuration is not allowing access from a web application. So I reset the config as per the below screenshot
Previous config of the custom header
New configuration of the custom header
After implementation of the new config Power bi login page is able to open in the iframe, but when I am passing the credentials reports server workspace is not opening. Can someone please suggest any configuration that I missed or any approach which I need to take so that I can render the report in iframe after the implementation of the custom authentication?
