[Samba] Configuring Samba as a file server to use AD authentication

Fair point on Ubuntu.  Though, there is no value added by mentioning that as I am already seeking help here. :-)
What I was searching for was 'how to start winbindd' which doesn't provide any valuable excerpts beyond that.

Upon rebooting the machine winbindd is not operating all the same however, so I am puzzled why this is an issue for me.

Firstly, can I make a recommendation, forget Ubuntu forums, read the Samba wiki or ask here instead ;-)

Just joining a machine to the domain will not start winbind, this is just like any of the Samba binaries, it needs to be started by whatever your OS uses to start programs. I think the problem is that Debian uses a script called 'samba', this starts two other scripts 'smbd' and 'nmbd', it does not start winbind. I think if you look, you will find there is another script called 'winbind', guess what this does ? ;-) Do what ever you do to start samba, but replace 'samba' with 'winbind', it should then start.
I haven't a clue how you start packages on Ubuntu now, I don't use it.

You could always reboot the server, just like the person in your link did, this is what started winbind, not the join.
