Validate authenticated user outside the symfony world (simplesamlphp)

[fischel]

Hi everybody,

I have a webapp with symfony5 and I like to include some external services to my users. I do this with simplesamlphp. You can setup a symfony-project with simplesamlphp, but simplesamlphp has it's own web-folder, so you can say, it's outside the symfony-world. In this other world I like to validate if the user (from symfony) is authenticated. This happens in simplesaml in a custommodule.

In this customscript I have to setup the minimum-code for validate an existing and authenticated user. So I copied the most important lines from the public/index.php to my customcode, but I have no idea how to validate the authenticated user. Goal is to get a $user if an authenticated user exist - if not then NULL.

In my auth-class I started with:

$kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']);
$request = Request::createFromGlobals();

// Session?

$user = .... ?

I hope you understand my problem. May some you had the same problem and can give me a solution or some help.

Thanks,
Stephan
