Well that is strange, I normally just remove the smb.conf and run the 
samba-tool provision command, this should create a new database and smb.conf

What exactly do you mean by '--configure', I normally connect that with 
compiling Samba, not with provisioning a new domain.

If you removed the smb.conf, there wouldn't be one, unless you had 
re-installed the Samba packages and you would then probably have one for 
a standalone server, but you say it wanted a smb.conf ????

Running samba-tool

Ah, that is where '--configure' is coming from.
Never run that command, what does it do ?

Did you re-install winbind ?

 From the sound of it, you are re-installing Samba.

I see that someone has already posted the 'recipe' whilst I was writing 
this.

I would ensure that you have these packages installed:

acl attr samba smbclient winbind libnss-winbind libpam-winbind ntp 
ldb-tools krb5-user python3-setproctitle

Ensure that there is no smb.conf

Then provision Samba with:

samba-tool domain provision --use-rfc2307 --interactive

Answer the questions, if unsure of the answers, please ask.
