[keycloak-user] How to check permissions on lot of resources

[Teddy CHAMBARD]

Hello,


I'm trying to protect resources with keycloak, but I wonder how to protect millions...

I created successfully resources with the Protection API (UMA 2.0), and also created necessary permsions and policies with the Admin REST API.


What I would like to do is simply get the list of resources I should be able to access.


To simplify my needs, here is a simple example :


Bob asks for resource1 and resource2 throught entitlement API

Regarding my policies and permissions Bob only have rights on resource 1 but not on resource2.


I was thinking making a POST request with the following payload :


{
    "permissions" : [
        {
            "resource_set_name" : "resource1"
        }, {
            "resource_set_name" : "resource2"
        }
    ]
}


would return a RPT with the list of permitted resources (resource1), but I got 403 forbidden without the list of granted resources.



So, I know I could run two separated requests to get my authorizations, but when I have thousands of resources to check, I can't run thousands http requests on entitlement API.


The question is how can I filter the data I retrieved from my database with keycloak in order to get only granted data ?



Keycloak is wonderful, and I would really continue to use it despite this trouble that I encounter.


Thank you very much by advance for your help.
