Hi Rowland,
Thanks for your response 🙏

Is it ok to have 2 records on the
CN=DC4,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=nicho,DC=com
?

20.04 comes with Samba 4.15.13, so where did you get the 4.19.5
packages from ?
deb http://ppa.launchpad.net/linux-schools/samba-latest/ubuntu focal main

Please provide a list of the installed Samba packages.
it at dc4:~$ sudo apt list samba --installed
Listing... Done
samba/focal,now 2:4.19.5+karoshi-1~linuxschools1+focal1 amd64 [installed]

Probably not, but what does this command show:
it at dc4:~$ sudo ldbsearch -H /var/lib/samba/private/sam.ldb -P -b
'cn=Schema,cn=Configuration,DC=nicho,DC=com' -s base objectVersion
# record 1
dn: CN=Schema,CN=Configuration,DC=nicho,DC=com
objectVersion: 69

# returned 1 records
# 1 entries
# 0 referrals

Best Regards,
Nicho.
