[olug] nfs user map issues

[Sam Tetherow]

You can do UID mapping in NFS 'man exports' gives an explaination.  I 
haven't done it because I usually set my machines up with the same uids 
but when it isn't feasible or practical you should be able to map_static 
or map_daemon options in the exports file on the nfs server.
