[Samba] Ubuntu upstart script ad dc

[Max Kirchner]

I am running a samba ad on Ubuntu 16.04 configured as told in
https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller

The server is running fine currently, but I have to manually start it
after every reboot. The link to the upstart scripts in the wiki are dead:
https://wiki.samba.org/index.php/Samba_AD_Init_Script_Examples
Does anyone have a functioning init script I could use?
