Samba config with separate folder access?

Question

Samba

there is a public folder structure
(two more folders are nested in it)
-otdel1
-otdel2
there are users of department1 and department2.
It is necessary to organize that the users of department 1 can rummage through all the folders and write only to their own, so the user of department 2 writes only to their folder.
the public folder is connected as a network drive for all users.
I know how to organize access to individual folders, but what about nested ones?

Answer 1

chown -R :wheel /public
chown -R :otdel1 /public/otdel1
chown -R :otdel2 /public/otdel2
chmod -R g=rwX,a=rX /public

Well, users, respectively, add to the desired groups
