What parameter does samba need for login-password authorization?

Question

linux

Samba 4. Installed everything as standard. Set up.
The server is needed for balls, not a domain controller. Just a regular server with a connection to a folder by login and password. But there is a connection from computers, not in the domain.
That is, if the computer is in a domain, I go to the server and see my shared folder.
I click - asks for a username and password. I enter and at the top there is a download (the progress bar in Windows, in the address bar of the explorer, where is the path to the folder) - i.e. the system is trying to connect to the ball. And after a minute it says that the network path was not found or there is no access to the resource - contact the administrator.
From computers not in the domain - it is perfectly connected. And it doesn't matter what group name these computers have.

[global]
workgroup = WORKGROUP

read

and a couple more related articles from ibm, chewed very well.

Answer 3

In general, I realized my mistake. It looks like nothing is needed.
You just need to enter the username not user, but WORKGROUP\user for domain computers.
In the same place, MYDOMAIN \ is attached to the name by default.
