[keycloak-user] Spring + keycloak - cannot get auth username

[Ondra Pala]

Hello,

Why I can´t get username of logged user? I can try get this information
from Principal, HttpServletResponse ... but still null.

Our application use for authentification Keycloak, after successfull login,
user is redirect to another url (on the same server) in Java Spring MVC
application.

Thanks for your answers.
