Hi everyone.  
Today I did a clean install of Mautic v5[beta1], and unfortunately, login with the SAML provider doesn’t work.

In log file, message is:

> mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\ClassNotFoundError: “Attempted to load class “Controller” from namespace “Symfony\Bundle\FrameworkBundle\Controller”. Did you forget a “use” statement for another namespace?” at /var/www/html/vendor/lightsaml/sp-bundle/src/LightSaml/SpBundle/Controller/DefaultController.php line 17 {“exception”:“[object] (Symfony\Component\ErrorHandler\Error\ClassNotFoundError(code: 0): Attempted to load class "Controller" from namespace "Symfony\Bundle\FrameworkBundle\Controller".\nDid you forget a "use" statement for another namespace? at /var/www/html/vendor/lightsaml/sp-bundle/src/LightSaml/SpBundle/Controller/DefaultController.php:17)”}

Some steps to fix it?

Thanks!

Hi folks,

This is resolved via [Add support Symfony 5 for controller by pasxel · Pull Request #1 · mautic/SpBundle · GitHub](https://github.com/mautic/SpBundle/pull/1) and should be released in the General Availability release.

If you want to test it you can use Gitpod on the default branch, check [https://mau.tc/tester](https://mau.tc/tester) for more info!
