Problem using Access control lists for new users, ex ( afolder created in skel directoy have acl set, it should apply to new users)

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
