I usually agree, but in this case I've seen that warning and voluntarily 
ignored it because it worked for 2 days...
I thought I was lucky ;-)

I've changed smb.conf as suggested, then changed permissions from Linux 
(Windows Explorer gave access denied when enumerating object content):

# setfacl -m "default:group:SAMDOM:rwx" /
# setfacl -m "group:SAMDOM\Domain Admins:rwx" /
# ... restricted access at minimum ...
# setfacl -m "default:other::" /
# setfacl -m "other::" /

Now the share works and I can edit/copy/delete files without issues.

There's a last thing I'd like to fix:
when I create a new file, it got created with these permissions:

# ls -l
-rwxrwx---+   1 3000000 users     0 Jul  5 15:11 'New text document.txt'*

Is there a way to force it being created with root:root as owner and 
possibly with more strict permissions (I'm scared I'll forgot the 
permission issue in the near future)?

Rowland, thanks for your help and patience ;-)
