I think I see what your problem is. I've done some similar things myself,
in a bigger, more confusing, scale (lots of cross-mixed directories and
users)! 

BTW, I looked for the Linux ACL pages and all the links pointed to the
exact same URL which doesn't exist anymore. Can anyone shed some light on
this matter?

Your problem here is basically a UNIX permissions one.

As for what samba is concerned, you have to set the umask for "group all
access", ie, "create mode = 0770" or whatever you wish in the pertaining
section of smb.conf, as long as you give the group full perms.

Don't forget to set the common directory with the sgid bit ("chmod 2770
dir") for this is the really important bit which makes the difference!

Hope to help,
