• the second is, when an user want to access to directly to the application using an url, he is redirect to the cas server for login, but after enter his username and password he his redirect to de login_check path and got this error :
  "file_get_contents(https://domain/cas-server/serviceValidate?service=http://application_name/app_dev.php%2Flogin_check&ticket=XXX): failed to open stream: operation failed" at xxx\vendor\kriswallsmith\buzz\lib\Buzz\Client\FileGetContents.php line 64
