Just my 2cents tip: I force the group to have rwx (with directory and
file mask) and use either sticky bit on the folder (usually quite
sufficient) and in some rare case default posix ACL so that every
folders and files created will be unix group writtable and then I use
the NT ACL to make fine grained access.
BTW if you do not set any NT ACL you have by default a mapping of POSIX
ACL to NT ACL done by samba4.
