How to build automatic authorization when entering the site?

Question

symfony

Good afternoon.

It is required to build automatic authorization when entering a site with Symfony 5 without a registration form. The site is running on IIS, and the current user login will be in the $_SERVER['AUTH_USER'] variable. This is the login you need to use. How can this be built?

Answer 1

Disable anonymous authorization, leave only WINDOWS authorization, IIS will do the rest for you.
