Failed log on (Failure message: Session information is not sufficient for single-sign-on.)

jdiamondI had the same error in my custom Web Application, and when I researched deeper in my code when I access one page using the TempData object for my MVC Controller, the system stop to work.

To solve that issue it´s only to change the TempData object for another option to store temporary data in your application and the system goes back to run properly.

I hope I helped,

Best Regards,
