ok. I know you have gotten this resiolved by starting with
a clean server, but this is for the archives....

There are several layers of access control.  You always
get the most restrictive set.  Think of them as filters that you
have to successfully pass through (similar to PAM).

There are two places of share access control.  The first is
the share ACL stored in share_info.tdb (for now) and
defaults to Everyone (Full Control).   The second layer
is the read/write list, read only, et.al. in smb.conf.

Then once you get to the file system, the OS says yes or
now based on the on-disk permissions and your current uid/gids

Hope this helps.

cheers, jerry
