Ricky, Being new to all of this, it's been great help so far already! I've been trying to evaluate the available standards to see what I need to work with on this module. And from what I've been reading over the last month or so, I'd narrowed down to SAML and WS-Security on the basis that they work well together and they're very popular. It'd just been a week since I'd heard about XACML (duh!) and I must admit it had me all confused! :-) thx for helpin me out there! Ok so you've told me about what SAML does (and I guess I can use OpenSAML APIs for development there) but what about WS-Security? Does embedding SAML assertions into the SOAP Security Header within the <wsse:Security> tag complete the picture? Also, how does JAAS compare to all of these standards in authorization? Where would it fit in?
Lotsa questions there! :-( Regards, Nisha -----Original Message----- From: Ricky Ho [mailto:[EMAIL PROTECTED] Sent: Sunday, March 16, 2003 10:08 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Authorization using WS security and SAML SAML is about specifying the XML format of your authorization decision outcome (authorization assertion). It also defines a protocol how to request the assertion. SAML doesn't describe how the decision should be made. XACML is attempting to standardize how such decision rules should be specified. So it is completely solving an orthogonal problem. I'm not sure how important to standardize decision making rules because there is NO "inter-operability" requirement for that. There is NO need to communicating how I made my decision to my business partners. The value of XACML is "portability" of my decision criteria across multiple vendor products. However, "portability" has never been a goal for any XML standard. It is arguable how important XACML will be.
