[Samba] ACLs under windows 7 - you do not have permissions to access

[sisu .]

Hi all again,

Finally I found the source of my problem, it was I set  "force group = root" parameter on my shares, It was really useful for me since whether an user created a file it forced the group root as a primary root and then as I had the default acls (for secondary group)  for example:

#ll
drwxrwx---+ 2 user root 6 Feb  1 11:04 test_file

default:group:tech:r-x

thus only the members of this secondary group (tech) were able to interact with that file due to the default acl I had on this directory. 
Currently the problem that I have is all the users are in the same group 'company' then as I can't force the group as root the default group will be 'company', which implies everybody will have access to this file.

drwxrwx---+ 2 user company 6 Feb  1 11:14 test_file2


Any suggestion? Thanks again for your support !
