Does this server need to be configured with the uid and maybe gid of the=20
user to
be accessing files on the file system?  I have seen some situations,=20
typically
with Microsoft servers, that need to be accessed using a specific uid/gid
combination.  Since these systems don't have the concept of uid and gid=20
anyway,
perhaps this is required here.

At Connectathon, it seems like some of the servers need to be accessed us=
ing
magic uids and gids...
