Samba configuration

Good morning.

I installed Samba on my server but I need some help in consfiguratin:

1. Access only for users from my network
2. Create catalog for all users, users not login - only read, users log in - all(read, create, write)
3. Create catalog for users group. If we create some group users from that group have access to that catalog (read, create, write)
4. All users have acces to their home catalog
5. No time synchronization with server

Thank You very much.
