[keycloak-user] Keycloak policy enforcer for bearer-only client

[Juan Camilo Vanegas]

Hi Pedro.

Thanks for your help. So basically, if you need to protect your resources
on the back-end, you should use a confidential client, but the
keycloak.json configuration file should have the bearer-only key set to
true, to you avoid redirecting the user to the login page and instead send
a 403  Access denied response. Is this correct?

Best regards,
