There is no winbindd--it was never installed. I don't recall exactly why I
didn't install it, but I seem to recall something about Samba4 in an AD
domain control role not needing it. I ended up using SSS instead.
Sanatized smb.conf:
# Global parameters
[global]
workgroup = DCS
realm = DCS.LOCAL
netbios name = SERVER
server role = active directory domain controller
dns forwarder = 8.8.8.8
idmap_ldb:use rfc2307 = yes
debug level = 0
[netlogon]
path = /var/lib/samba/sysvol/dcs.local/scripts
read only = No
[sysvol]
path = /var/lib/samba/sysvol
read only = No
# Network shares.
[Share]
comment = Sahre.
path = /srv/samba/Share
read only = no
browsable = no
