Mon problème est une fois que je suis connectée et que je souhaite accéder à mon profil.
Le site a été développé avec Sonata et donc la page profile est faite avec des blocks sonata. J'accède bien à la page mais j'ai des erreurs car firstname et lastname ne sont pas des propriétés de mon $user. C'est étonnant car ça marche sur l'intranet en production et que en dev je n'ai touché à rien. En essayant de résoudre le problème, je me rends compte que mon $user est de type App/Entity/User et non un LdapUser comme je l'aurai pensé.
Mes questions sont:

• Est-ce grave si c'est un user et non un LdapUser? Cela veut-il dire que je ne suis pas connectée via LDAP?
• Je souhaite récupérer le givenName qui est dans mon LDAP pour chaque utilisateur mais je n'arrive pas à trouver où sont initialisés les utilisateurs lors de leur connexion

Merci d'avance pour votre temps, je suis vraiment coincée :/

Bonjour,

Je pense que vous devriez comparer les fichiers de configurations de dév et ceux de production, notamment les fichiers suivants :

• config/packages/security.yaml ;
• config/packages/dev/security.yaml ;
• config/packages/prod/security.yaml.

C'est eux qui vous décrirons les nuances que vous constatez entre la production et le développement.

N'hésitez pas à nous montrer les différences si cela ne vous aide pas.

Bonjour. Merci de votre retour. Malheureusement je n'ai qu'un seul fichier security.yaml qui se trouve dans config/packages. J'ai fini par résoudre le problème en allant chercher le firstname et lastname en dans ma BDD au lieu d'essayer de récupérer via le LDAP.
