Subject Re: [DISCUSS] - Privileges in Syncope 2.1.0
Date Thu, 07 Sep 2017 16:20:36 GMT
Hi Francesco,

A few further thoughts on this:

a) Instead of having both entitlements + privileges, would it make sense to
only have privileges, where the "entitlements" are privileges on the
Syncope application? It would seem less confusing and kind of neat to model
everything as a single concept, but maybe there are practical reasons to
keep them separate?

b) Perhaps the Privileges/Applications could have a few standard
attributes, such as "name", "displayName", etc, as well as the JSON

c) The Application concept is a bit problematic for us, as it requires us
to model Applications in Syncope, whereas we are content to have the
privileges be interpreted by our applications without having to create the
applications in Syncope. For example, a user A might have Role R with
privilege P, but we may wish P to apply to a future application for
example, something we won't be able to model if is it mandatory to
associate a privilege with an application.
