Centos123, the more I think about your situation and what you are trying to accomplish I am coming to the conclusion that you would be well served by different short and long term approaches. In the short term, you could rely on using special SMB users and creating SMB Passwords for users to access a simple share. In the long term, I think you will want to migrate to a more advanced system that uses directory indexing and inter-server authentication with trust domains. Samba is quite capable of handling both of these scenarios, but one is much more complex to set up than the other and I am not sure your quite ready for the more complex setup.
Seeing your posts over the last few months, I can tell that you have been making a lot of progress in improving you understanding and capabilities in administering a Linux system. You are certainly to be commended for this effort. The fact is that it is something that takes years and years to achieve a mastery of and even then there will be many parts that are completely unknown. Please always
be cautious about someone handing you a configuration and saying, "do this". Unless you research and understand what the commands and configurations do, you may be setting yourself up for a bad situation.
What I might suggest to you is a free book called Samba by example: link
. There is also a PDF version. It starts out showing implementations of simple shares and discusses the parameters required to work with them. It then builds upon this, implementing more complex scenarios up to and including domain controllers. It is not something you will be able to swallow in one or two sittings, but it might be a good guide to help you along with your goal.
