The way in which dos attributes are mapped to linux is a little tricky,
and has evolved over time. The following is my present understanding,
and may be a little off.
The older way (still supported) was to map the dos attributes using the
unix attributes in a convoluted sort of way (not the way in which the
unix attributes were intended). The "map xxx" configuration parameters
control this type of mapping. This method makes it difficult (if not
impossible) to use both samba and unix permission settings concurrently.
Then along came ext2 extended attribute capabilities (or at least the
ability for samba to use them). This method stores the dos attributes in
the extended attributes area of the ext2 filesystem, and leaves the unix
permission bits alone. This method allows unix and dos permissions to
coexist nicely, although the authentication mechanisms are entirely
separate. In order to use this method, you need "store dos attributes =
yes" in your configuration, and you need to be sure that the filesystem
is mounted with the "user_xattr" option (in fstab).
For your situation, I'd try this in smb.conf:
map archive = no
map hidden = no
map read only = no
map system = no
store dos attributes = yes
dos filemode = yes
either globally or on each share, and also add "user_xattr" to fstab for
the appropriate filesystem. (user_xattr is not on by default)
I'm guessing that'll work for you. Let me know.
