Subject Re: Notion of user roles in the PHP Reference Gateway
Date Tue, 01 Jul 2014 14:39:35 GMT
Hi Supun,

You can try XACML. But XACML is for fine grained authorisation. But in
gateways we expect there will be well defined roles and well defined
authorization points. Therefore, IMO, we don't need XACML authorisation.
(At least for now).

Thanks
