It seems that Samba doesn't like at all. I've followed various tutorials and I can't get Windows 8 to work properly with a Ubuntu Server as domain controller. This week i've downloaded ubuntu 14.04 lts and set a fast domain configuration. As usual all other Windows version (XP and 7) work but the newest M$ nightmare doesn't. In this try it doesn't even join the domain, keeps saying the my username or password are wrong.

My /etc/samba/smb.conf

# Global parameters
[global]
        workgroup = DOMAIN
        realm = DOMAIN.LAN
        netbios name = DOM
        server role = active directory domain controller
        dns forwarder = 8.8.8.8
        idmap_ldb:use rfc2307 = yes

[netlogon]
        path = /var/lib/samba/sysvol/domain.lan/scripts
        read only = No

[sysvol]
        path = /var/lib/samba/sysvol
        read only = No

[test]
        directory mode = 0750
        path = /SHARES/test
        read only = no

Does anyone have a tutorial that really works? Because I've tried many, each one with different configurations that works only with the people that made them.

And is there a way to import my old AD users, computers and ID in a way that I won't need to rejoin all computers?
