The MACE-paccman Working Group provides a venue for discussion and development of access management material in the context of MACE and the Internet2 Middleware Initiative. It was co-chaired by Tom Dopirak, Carnegie Mellon University, and Keith Hazelton, University of Wisconsin - Madison. Working Group Flywheel is Steve Olshansky <steveo AT>.
