Subject: Re: XACML and OGSA SAML AuthzDecisionQuery/Response proposals. Forwarded message from David Chadwick.
Colleagues, Would it be possible to devote a good portion of the agenda on 21 August (probably going until 11:30am EDT), or else the entire Focus Group meeting on 28 August to discussion of a joint SAML 2.0 Authz proposal with the authors of the OGSA proposal? Anne Anderson ------- start of forwarded message ------- From: David Chadwick <email@example.com> To: Anne.Anderson@sun.com Subject: Re: XACML and OGSA SAML AuthzDecisionQuery/Response proposals Date: Tue, 29 Jul 2003 16:03:59 +0100 This is a multi-part message in MIME format. --------------E1022A89F849BCBA3F1DAA44 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Dear Anne I guess we have a cultural difference in the meaning of the term meeting. In the UK it invariably means a physical face to face meeting. The other is a telephone conference call, not a meeting :-) So 14 th Aug would be no good for me, as I will high in the sky somewhere between Colorado and NY. The 21st will be OK though, as I can be back in the office for that day, or the 28th either. regards David Anne Anderson wrote: > > Dear David, > > I was actually thinking of a telephone conference meeting.
