Re: [keycloak-user] Policy enforcer without roles in token

Hi Pedro, thank you for your reply. No, i wasn't the one who requested the feature, anyway i'm still interested into it. Our use case includes several microservices (which represents modules of our PaaS) which performs authorization checks against realm based roles. Every microservices has each own client containing its authorization checks.

Besides the PR (which is really really interesting and i hope it will be included in further releases), what are your recommendations to reduce the access token size? I'm asking this because in some browsers there are limits (4KB) about cookies & headers length. I can imagine those solutions: - Keep the token "light" and perform a token exchange into our gateway once we receive the token from the single page application, in order to retrieve a new token with all the realms roles associated to the user

- Use some particular mode of the adapter which will do the necessary to retrieve the roles (but i can't find something like that in the docs)

- Use RPT? Once the gateway receives the access token, perform the RPT request to retrieve a token with all the permissions for the particular client

- Something else unknown to us? :)

Have you ever faced this kind of problem?
