Samba use Active Directory users

I inherited an ubuntu 8.10 server that is currently running as a samba server and apache web server. I would like to make a new server with ubuntu 19.10 and copy the existing configurations on that one. I usually start from scratch and I never configured samba to integrate with active directory. Will this config in smb.conf be enough?
