I have a NAS system at work that I use both NFS to the Linux servers and
Samba for Windows. What is really messy is that because of the
Unix/Linux permission scheme, I had to use Linux user and group IDs, but
I had to use Windows user names. Fortunately we are a relatively small
office and most of us used to use the same Windows and Linux user names
(our IBM names are different).
