[Samba] Can't find machine account

[Robert A Wooldridge]

I'm trying to join as a DC using Debian Buster and samba package 
(v4.9.5) and I'm getting this error when I attempt to join:

> Could not find machine account in secrets database: Failed to fetch 
> machine account password for DOM from both secrets.ldb (Could not find 
> entry to match filter: '(&(flatname=DOM)(objectclass=primaryDomain))' 
> base: 'cn=Primary Domains': No such object: dsdb_search at 
> ../source4/dsdb/common/util.c:4705) and from 
> /var/lib/samba/private/secrets.tdb: NT_STATUS_CANT_ACCESS_DOMAIN_INFO

Any ideas on what to do?
