[Sergio Belkin]

Hi, I use the Van Bell repo, I've upgraded from samba 4.7 to samba 4.9 but
now it fails, these are the errors:

I've no modified the smb.conf which is:

[global]
        dns forwarder = 8.8.8.8
        netbios name = SAMBA4
        realm = EXAMPLE.COM
    interfaces = lo eth0
        server role = active directory domain controller
        workgroup = EXAMPLE
        idmap_ldb:use rfc2307 = yes
        # Audit settings
    full_audit:prefix = %u|%I|%m|%S
    full_audit:failure = connect
    full_audit:success =  mkdir rmdir read pread write pwrite rename unlink
    full_audit:facility = local5
    full_audit:priority = notice
        # TLS settings
        tls enabled = yes
        tls certfile = tls/ldap.example-aid.com/fullchain.pem
        tls keyfile = tls/ldap.example-aid.com/privkey.pem
        tls cafile =
        #log auth
        log level = 1 auth_audit:3 auth_json_audit:3
[netlogon]
        path = /var/lib/samba/sysvol/example-aid.com/scripts
        read only = No
[sysvol]
        path = /var/lib/samba/sysvol
        read only = No
[lab]
       path = /srv/samba/lab
       read only = no
           vfs objects = full_audit

I cannot even 'to kinit', I get:
kinit: krb5_get_init_creds: unable to reach any KDC in realm EXAMPLE.COM

Please could you help me?

Thanks in advance...
