Hi Rowland,

Sorry I missed out on the OS.

CentOS Linux release 7.6.1810 (Core)

smb.conf
# Global parameters
[global]
        bind interfaces only = Yes
        interfaces = lo ens192
        netbios name = SERVER1
        realm = EXAMPLE.COM
        server role = active directory domain controller
        workgroup = WORKGROUP
        idmap_ldb:use rfc2307  = yes
        ldap server require strong auth = no
        template shell = /bin/bash
        template homedir = /home/%U
        time server = yes

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/example.com/scripts
        read only = No

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = No

Regards
Alfonso
