[keycloak-user] Authorization transfer

[Corentin Dupont]

In parallel with the domains authorizations, I have other policies, such as
"owner" policies (similar to the photoz example).
I coded the owner policy with javascript:

var context = $evaluation.getContext();
var permission = $evaluation.getPermission();
var identity = context.getIdentity();
if (identity.id == permission.getResource().getOwner()) {
    $evaluation.grant();
}

But it leads to this result when evaluating a user:

Result*: DENY*

Policies:
- *Can access domain
<http://localhost:8080/auth/admin/master/console/#/realms/waziup/clients/0892e431-5daf-413e-b4cf-eaee121ee447/authz/resource-server/permission/resource/7323164c-3009-4cf8-9a48-b37cf009d2fe>*
decision was *PERMIT* by *UNANIMOUS* decision.

   - *Users in domain
   <http://localhost:8080/auth/admin/master/console/#/realms/waziup/clients/0892e431-5daf-413e-b4cf-eaee121ee447/authz/resource-server/policy/user/ef112bc8-c7a8-4300-be92-d0c9d0300971>*
   voted to *PERMIT* .

*Can delete MyHouse
<http://localhost:8080/auth/admin/master/console/#/realms/waziup/clients/0892e431-5daf-413e-b4cf-eaee121ee447/authz/resource-server/permission/scope/53278490-b9c8-41f6-b2a5-bef5a0be6e73>*
decision was *DENY* by *UNANIMOUS* decision.

   - *owner can access
   <http://localhost:8080/auth/admin/master/console/#/realms/waziup/clients/0892e431-5daf-413e-b4cf-eaee121ee447/authz/resource-server/policy/js/762cf51c-9ff1-4b44-ba79-6890189db0f2>*
   voted to *DENY*.


The two permissions are overlapping, so it seems normal that both got
evaluated.
But why the java policy ("Grant_owner") voted DENY?
I didn't mention explicitly the deny in the code...
I think that if you are the owner, you should be granted. But if you are
not the owner, no decision can be taken by the policy...
