I created a file share system with 9 file shares that go to different people.

I can’t limit access or specify who should have access to what.

I’ve read a bunch of documentation, but I don’t think I understand it correctly.

I tried to give access through Access Control(IAM) I can see that the correct people are in the correct file share, but in practice every person has access to all the file shares.

I read about ACLs but that is for containers, and I want to used file shares for structured data. And a documentation about entra authentication.

I have tried enabling, Active Directory Domain Services (AD DS), Microsoft Entra Domain Services & Microsoft Entra Kerberos. And looked in the configurations. Set share-level permissions.

If something is unclear, please ask.
