Facing issues with ACL

I have a doubt regarding ACL

I want to give permissions to a group using ACL

A directory created in SKEL directory needs to have a default ACL set that allows the
members of the group “linux” to read all files and subdirectories.

But after doing above steps, if i add new user to a system with group as linux it
is not applying default ACL.Need some help

My first thought was that you should consult an Orthopedic surgeon however maybe this can help >> http://superuser.com/questions/742243/how-can-i-set-default-permission-with-acl-in-linux rotfl!
