Subject: Re: [xacml-users] RBAC using XACML


i dont know much about the use of XACML over the network, but i think so
SAML standard can be used to wrap an XACML request and response over the

for SAML there are some implemenatation (open source) so check out them, if
they are going to solve you problem.
