How to set up smb in freenas?

Question

FreeBSD

Good afternoon, we decided in the office to transfer the file washer from Windows to tench, and the speed is higher and the wasps will not be clogged by the user's threshing floor. Faced with the problem of issuing rights to smb, I need to assign 3.4 groups of users to each share with different rights, but as soon as I assign the rights of any group, I immediately lose access to it, in hell I am the administrator of the domain, the groups below me are rights. Plz tell me how to win.
