How to stop permissions inheritance?
 

Hello,

I would like to know if it's possible to stop permissions inheritance?

I've a level-1 folder named "common", wherein all users can read/write.
Inside this folder, I've created a level-2 folder named "private" wherein members of "abc" group can enter/read/write.

I can build correctly this structure, but I'd like that members of "abc" are not able to rename "private" folder, and I don't succeed to do that!
I've tried many way, including ACL, but it doesn't work!
I'm not sure, but I think the problem is that members of "abc" group are member of "users" (member of child folder/group are member of parent folder/group)!

Do you know how can I do that?

Thanks for your help,
Chris

\common\private\

root@server:/# getfacl common
# file: common
# owner: root
# group: users
# flags: -s-
user::rwx
group::rwx
other::---

root@server:/common# getfacl private
# file: private
# owner: root
# group: abc
# flags: -s-
user::rwx
group::rwx
other::---

If you set the "sticky" bit on the "common" directory ("chmod +t common"), users will be able to delete or rename only the files that they own. That should suffice unless it proves too restrictive for the ordinary files there.

Just remove the group permissions.
