Spring avait besoin d'un bean de type 'AuthenticationManager'

Question

J'ai essayé de suivre un tutoriel trouvé ICI pour configurer une démo pour m'aider à comprendre l'authentification unique sur ma machine locale avant de l'implémenter dans un autre projet. J'ai rencontré un problème qui m'a bloqué. Je reçois et une erreur me dit d'ajouter un bean. Veuillez me faire savoir quel code me manque. Je ne parviens pas à exécuter le programme.
