samba - Aug 2013 - sharing files as standalone server in samba4

I am a little confuse here, if I want to share a folder with samba4 but as a
standalone server, the same procedure applies as for the DC mode?

# mkdir -p /srv/samba/Demo/

 Add a new share to your smb.conf:

[Demo]
     path = /srv/samba/Demo/
     read only = no


and managing permissions from windows as explained here
https://wiki.samba.org/index.php/Setup_and_configure_file_shares?


or it is like the samba 3 way, doing chmod to the folder and adding or
restricting users in the smb.conf with for example write list, read list, valid
users, etc options?

for example



Mkdir 
sharedfolder

Chgrp
?R users sharedfolder *1

Chmod 2770 sharedfolder





[sharedfiles]

Path=/home/easgs/sharedfolder

Read
list= a,b,c

Write
list = d,e,f

Force
group = users

Guest
ok = no

Valid
users = a,b,c,d,e,f, @users

Directory
mask = 2770

Create
mask = 2770

Force
create mode = 2770

Force directory mode = 2770

oplocks = no

level2 oplocks = no


thanks
