[Samba] samba and domain authentification(newbie)

[Michael F]

Hello!
I want to make a samba server that let the users connected to domain
to acces the shares without promting for password once they are
authentificated to domain. I also want to restrict the acces on share
to some usernames. I try to made this using the security setting to
domain but it worked after i made coresponding usernames that i shared
the resource. Can i make samba use the domain controler?

Thanks in advice!
