[Samba] share permissions

[Donald W Watson]

If I have a samba server with the following share:

      [share1]
            readlist    = user1
            path = /tmp/share1
            writelist = user2

On the surface this indicates that user1 can only read files in the share,
while user2 and read and write.  However:

1. If the share is mounted on another unix machine with "mount -t cifs"
what effect does "-o username=<some user> have on the read/write behavior
of files in the share?

2. What effect do unix ownership and permissions of the files in the share
have on read/write behavior of those files?  Does normal unix behavior
apply (e.g., a file in the share has rw permissions for root, so root can
write the file regardless of who mounted the share)?  What if root is the
file owner?
