I was configuring aws sso with my php application, and for the application i had used simplesamlphp library https://simplesamlphp.org/docs/stable/simplesamlphp-idp#section_1. i followed the documentation and when i m accessing the application from Aws sso dashboard it works perfectly fine. I have also done certificate configuration in my application. But when i m trying to login from my php application at that time i m getting the error. Plz let me know if anyone knows the solution. Sometimes i get 403 error also.
