How to organize samba access policies?

Question

Access rights

Good day to all.
Can anyone give a link to a good article or tell in a nutshell how to organize such access policies:
For example, there are 2 users dir. and com. dir. There is a spherical folder (share) in it there are dir and komdir folders
How to correctly describe what dir would be in the config file. could read and write to all folders and share. and com. dir. could only work in its own folder. And for example, that there would be a shared folder in share where everyone can work, but only owners and dir can delete files.
Climbed the entire Internet, shoveled a lot of articles. But I did not find a single good example or description, mostly standard ones (everything is available to everyone.)
I tried it myself through write list, read list. But how ugly. When I set these parameters in the main folder, they also apply to subfolders.
Maybe someone will help. I will be very grateful.

Answer 1

Separate the folders into separate balls. That is, make 3 balls: common, for dir and komdir.
And for each of them already make your own access-list.
