If you are enforcing access to your app based on scopes you won't be able to perform the action because it is missing.

But I agree, I also think we should just return a DENY for that case. I can't remember now the use case we had in mind for it, but I'm glad to review this and change.

It should be a matter of ignoring resources associated with policies when they are scope-based. Would you mind creating a JIRA (so we can track the reporter)?

Regards.

Hi,
in Authorization Services there is something that feels like a unintuitive thing – or bug – to me:
In Authorization Services, I have a Resource R1, there are three associated scopes S1,S2,S3.
I create a scope based permission + user-based policy to allow a user u1 access to R1 only for S1.
Now I evaluate:

·         Can u1 do S1 on R1? -> permit

·         Can u1 do S2 on R1? -> permit   (WAT?)
I see, that the second case returns permit with no scopes, but I would expect deny.
Is this intended behavior and I would need to filter this again after evaluation?
