LDAP: Get more informations from account

[henri9813]

Description
Actually, the ldap security component described here: https://symfony.com/doc/current/security/ldap.html

return only a username.

It could be funny to get more data like, email address, or other..

Example

providers:
        my_ldap:
            ldap:
                service: Symfony\Component\Ldap\Ldap
                base_dn: "ou=MyOU,ou=Users,dc=myldap,dc=com"
                search_dn: "cn=MyOU,dc=mydap,dc=com"
                search_password: "mySuperPassword"
                default_roles: ROLE_USER
                uid_key: cn

               #Additionnal data 
               email_field: email
               first_name: firstname
               last_name: lastname

Example in twig:

<a href="/profile">{{ app.user.firstname }} {{ app.user.lastname }} 

A cool things that i wanna done if that could exist, it to load gravatar images from the email that this new feature could give me..

Thank you ! :)
