Per action items from meeting of 21 Sep. 2006: A link for information on the International Grid Trust Federation (IGTF) and its activities with respect to the large-scale grids in science and academics is below: http://www.gridpma.org/ Information in general on path validation is available at http://tools.ietf.org/html/rfc3379 I will look for and try to supplement the above with information specific to path validation and related issues for the use of Bridge CAs and similar structures in grids as soon as possible. Note that The Americas Grid PMA (TAG PMA) has formed a working group on the above issue including members from the other PMAs, and that is currently in process. There is also extensive activity, especially in the Internet2, Educause and related sectors with respect to the use of Shibboleth with grids, including related PKI and X.509-embedding issues, see http://grid.ncsa.uiuc.edu/events/ggf18-shib-bof/ Best, Alan Alan Sill TIGRE Senior Scientist High Performance Computing Center TTU ==================================================================== : Alan Sill, Texas Tech University Office: Admin 233, MS 4-1167 : : e-mail: Alan.Sill@ttu.edu ph. 806-742-4350 fax 806-742-4358 : ====================================================================
