[Samba] Samba won't start on Centos 7 built from tarball

[samba.x.eliezer613 at spamgourmet.com]

Hi, not having much luck getting samba 4.8.3 to start on a CentOS 7.6 VM....

used samba-4.8.3.tar.gz
./configure
make
make install
samba-tool domain provision --use-rfc2307 --interactive

In /etc/samba there is one file, smb.conf with content of:
# Global parameters
[global]
        dns forwarder = 192.168.25.1
        netbios name = DC1
        realm = DC1.INTERNAL
        server role = active directory domain controller
        workgroup = REDACTED
        idmap_ldb:use rfc2307 = yes

[netlogon]
        path = /var/lib/samba/sysvol/dc1.internal/scripts
        read only = No

[sysvol]
        path = /var/lib/samba/sysvol
        read only = No

service samba start fails
