+the longer term.
+
+For pure file server work, the binaries users would expect from that
+series (nmbd, winbindd, smbpasswd) continue to be available. When
+running an AD DC, you only need to run 'samba' (not
+nmbd/smbd/winbind), as the required services are co-coordinated by this
+master binary.
+
+As DNS is an integral part of Active Directory, we also provide two DNS
+solutions, a simple internal DNS server for 'out of the box' configurations
+and a more elaborate BIND plugin using the BIND DLZ mechanism in versions
+9.8 and 9.9. During the provision, you can select which backend to use.
+With the internal backend, your DNS server is good to go.
+If you chose the BIND_DLZ backend, a configuration file will be generated
+for bind to make it use this plugin, as well as a file explaining how to
+set up bind.
+
+To provide accurate timestamps to Windows clients, we integrate with
+the NTP project to provide secured NTP replies. To use you need to
+start ntpd and configure it with the 'restrict ... ms-sntp' and
+ntpsigndsocket options.
+
+Finally, a new scripting interface has been added to Samba 4, allowing
+Python programs to interface to Samba's internals, and many tools and
+internal workings of the DC code is now implemented in python.
