NFS and map_static
I've setup a NFS server on my linux PC (Slackware 13.1) which has a Mac as a client. Obviously things like user names (UIDs) and groups (GIDs) don't match up between the client and the server. Since I'm the only user I manually syncronised my UID - fine. But there are a number of groups I'd like to map, e.g. "users" (GID=100) on the server, to "staff" (GID=20) on the Mac - which appear to be roughly equivalent. Having done a couple of searches on the 'net, it seems specifying a "map_static=/etc/mapfile.map" in /etc/exports would be a good way to solve my problem. However, on rebooting I get a message saying map_static is an unknown keyword.
Is map_static still supported? Some other sources on the 'net suggest it may have been removed? If so, what are my options for mapping groups (and squashing some others)? I really don't want to have to start using NIS if I can help it...
