[keycloak-user] Authorization at Keycloak level

[Edouard Kaiser]

Hi Pedro,

Thank you very much for your answer. Unfortunately that's what I was
afraid. The problem is, we don't have a classic Java/Servlet application,
so we can't use any of the Keycloak adapter available.

We might have to turn to another solution like Auth0.com which offers an
integrated authorization plugin, unless we find the courage to write our
own adapter.

Cheers,
