Thanks for your quick reaction. If you don't mind, I'd like to ask you -
or someone from the list for that matter - for a slightly more granular
answer. I was trained to avoid the Administrator or root as much as
possible, not least for accountability reasons. For most tasks on *nix and
Windows it is possible to grant rights more granular than using root. So I
reckon this holds true for Samba also. Most likely, it's a matter of
having the Admin user in the right *nix group?
