Nice Etienne,

  I put you on the agenda to talk a bit about it! ;-)

Take care,
Morris

>-This work uses the Common Open Policy Service (COPS) model defined in

>-COPS defines at least following 2 concepts :
>--  PDP = Policy Decision Point
>--  PEP = Policy Enforcement Point

>-Interoperability is achieved through an AuthZ Interop Profile, based on
>-the SAML v2 profile of XACML v2.

>-So I suggest that, before reinventing the wheel, we study in detail the

>--  The problems which they are encountering,
>--  The solutions which they are founding,
>--  The interoperable components which they are deploying and which we
