But out of curiosity, why is it difficult to change user IDs on all files? I assume that you control the storage? Isn't it just a chown -R away? For example, for our NIS passwd/shadow map we use 6-digit IDs...
Because... users have files - on their NFS home - on public NFS shares - on a partition of the local harddrive (and not necessarily limited to one machine) - on their home on the web server - on their home on the mailserver - on their home on the computing cluster all of which makes a change of user and group id slightly more involved than a 'chmod -R'. Nothing that couldn't be done, mind you, given enough round tuits - both for me and my users. As I said, it would have to be either a flag day (deploy a script with old-new mapping to all machines involved, lock out users, shut down services, run script), or piecemeal change (negociate time slot with user, log them out, annoy other users because you have to temporarily disable imap and smtp services, run said script). Both would need to be planned, communicated and negociated, and so take more time than I have.
