How can I make sure that a certain group of users cannot log in to the site?

Answer 1

You need to catch the authorization event OnBeforeUserLogin . In the event handler, check if the user belongs to a specific group. If it does, then throw an exception and return false, like so:

$APPLICATION->throwException('Под этим пользователем нельзя авторизовываться');
return false;
