I am in the process of developing one for our site. There's a utility called 'zap' (now something like unify_uids) that was written at University of Maryland that is useful for doing the mapping over to your unified user-id space once you've sorted out the administration. It reads a map of uids, opens the superblock, and frobs the inodes - fast, sure, and deadly - superblock death from above. mjr. -- Good software will grow smaller and faster as time goes by and the code is improved and features that proved to be less useful are weeded out.
