CAS authentication issue

CMS Version

2.3.9

Issue

Hello, I’m trying to set up CAS authentication but when I trying to log in (by clicking on CAS Login), here’s what I get :

I’m using Xibo with Docker.

Here’s my settings-custom.php file :

 <?php
     $authentication = new \Xibo\Middleware\CASAuthentication();
     $casSettings = array(
         'config' => array (
             'server' => 'xxx.xxx.fr',
             'port' => '443',
             'uri' => '/login'
         )
     );
 ?>

Running the debug, here’s what I get (I can provide more content, I just don’t want to send sensitive stuff) :

Authentication failure: Ticket not validated
Reason: bad response from the CAS server

Thanks for your help !
