To mount the Volume on the netatalk server, you must authenticate as a user.

When you copy a file over, it is created with the owner as the person 
who mounted the Volume. Permissions are lost.

Even if we use a program like rsync (the patched one that supports 
resource forks), which preserves permissions, the new files are written 
with the owner as the mounter.

Perhaps there is a config in netatalk to preserve permissions by user 
number, but I haven't found it yet.
