| Everyone, Please remember Wednesday's conference call (9:00a, 510-587-6076, ID:51002#, PW:0500#). Here's a proposed agenda: 1. UCnetID issues. 2. Policy issues. 3. Formal definition of our attributes. - UCnetID - Campus ID - Transaction ID (Datta has raised the issue of whether we really need this.) 4. Anything else? FYI, I've attached more explanation from Larry Woods on UCnetID matching. Also, there is a proposal for improving uDir at the very end of "Identity and Authentication: Next Steps," which is on our project web site at: http://www.ucop.edu/irc/itlc/ucfedauth/CommonAuthNextSteps/CommonAuthNextSteps-2003-12-17.html We can discuss this during Wednesday's call, probably as a follow-on to our current project.
