Hi,
In my point of view :
groups :
directors, members : DIRECTOR
read_folder, members : user1, user2
project1, members : user1
project1_read, members : user2
project2, members : user2
project2_read, members : user1
ACL entry :
FOLDER :
setfacl -m grp:directors:rwx FOLDER
setfacl -d -m grp:directors:rwx FOLDER
setfacl -m grp:read_folder:r-x FOLDER
PROJECT1 :
setfacl -m grp:directors:rwx PROJECT1
setfacl -d -m grp:directors:rwx PROJECT1
setfacl -m grp:project1:rwx PROJECT1
setfacl -d -m grp:project1:rwx PROJECT1
setfacl -m grp:project1_read:rwx PROJECT1
setfacl -d -m grp:project1_read:rwx PROJECT1
PROJECT2 :
setfacl -m grp:directors:rwx PROJECT2
setfacl -d -m grp:directors:rwx PROJECT2
setfacl -m grp:project2:rwx PROJECT2
setfacl -d -m grp:project2:rwx PROJECT2
setfacl -m grp:project2_read:rwx PROJECT2
setfacl -d -m grp:project2_read:rwx PROJECT2
In this config :
directors group can do anything he want
users in group project1 can do all in sub-folder PROJECT1
users in group project2 can do all in sub-folder PROJECT2
users in group project1_read can only read file and folders in sub-folder
PROJECT1
users in group project2 can only read file and folders in sub-folder
PROJECT2
the group read_folder is a group for permit user1 and user2 to read
content (visibility) of directory FOLDER, but cannot do anything in FOLDER
directory
Why -m and -d -m ?
The command setfacl -m modify acl entry for a file or a directory
If we add -d, the modification apply for default ACL entry.
default acl entry mean, what ACL must be applied when I create a file or a
directory under this directory who have this ACL ?
In my example, I use group because is more simple to manager than users.
if a user12 must have access to PROJECT1, we must just add to the group
project1 and it work (after a logout/login of user on windows client)
You can read the man of setfacl here : http://linux.die.net/man/1/setfacl
hope that help you
