Subject: Re: [ebxml-dev] XACML vs. SAML?


Not off-topic at all (see information about registry below).  XACML
works in conjunction with SAML.  For example:

- XACML receives a SAML request to determine if access should be granted
to a resource based on rule sets, or policies, that are defined by the
- Once the policy is evaluated and returns a true or false value to
indicate whether or not access is granted, an SAML authorization
decision assertion is returned, which is then processed accordingly. 

A SAML request contains information such as authentication username and
password, or other details about the individual making the request. This
information is then delivered to an application designed to process it
with the intended goal of using XACML to allow or deny access to an XML

The OASIS/ebXML Registry TC has just added XACML support to the Registry
V3 specification (which is in the final stages of completion by the TC).
