PowerBI Report Server - CustomSecuritySample - Login Popup after Timeout

[kjdevera]

Hi all,

We have Power BI Report Server Installed (On-prem).

We have successfully implemented Custom Forms Authentication using the CustomSecuritySample that has been mostly advised in this community which is:

https://github.com/Microsoft/Reporting-Services/tree/master/CustomSecuritySample

Unfortunately, after Time-out the  old Windows Authentication pop-up login keeps appearing. Has anyone else encountered this issue and does anyone have a advise/solution/fix?

Thanks in advance.

Hi Henry, 

Thank you very much for your response. I will investigate and try to apply solution 1.

I am more interested in solution 2 as it appears to be simpler. Unfortunately, I do not see authentication settings in the Power BI Report Server configuration manager. I have tried every setting group and i cannot see it. Can you please tell me how to find it? Here is my intial screen for reference, which :

Hi @kjdevera ,

One potential cause of this issue is that the session state is not being managed properly. In order to prevent the old Windows Authentication pop-up from appearing after a time-out, you'll need to ensure that the session state is being managed properly and that the user's authentication status is being persisted across requests.

One possible solution is to implement a session state provider that can manage the authentication status of your users. This will allow you to track the authentication status of each user and prevent the old Windows Authentication pop-up from appearing after a time-out.

Another potential solution is to disable the Windows Authentication pop-up altogether by configuring your Power BI Report Server to use only your custom forms authentication. This can be done by modifying the authentication settings in the Power BI Report Server configuration manager.

It's also worth noting that the CustomSecuritySample you mentioned is only a sample implementation of custom forms authentication, and may not be suitable for all scenarios.

If the problem is still not resolved, please provide detailed error information and related operation screenshoots. Looking forward to your reply.

Best Regards,
Henry
