Project mention: Laravel SSO with adfs | /r/PHPhelp | 2023-10-17

Hi! I build an app for client and he want to authenticate users with saml (adfs). I tried to configure this package : https://github.com/24Slides/laravel-saml2 . When I log in manually the user in the event loggedIn the user is logged. However, when I redirect with the relay state to a page after the login, the user doesn't exist (Auth:user in the blade is null). I add the middlegroup to web in the config file and I set the session same_site to none. It still doesn't work and I looked at all the resources I found on Google and reddit. I use Laravel 10.
