samba - Aug 2015 - Samba As PDC: Wrong Workgroup?

Hi There,

I've searched and searched.  Then searched some more.  Came up with
nothing.  So here I am.

I installed Samba as a PDC as per the HowTo, here:

   
http://www.tiltingatlinux.com/2014/04/basic-samba4-domain-controler-on-ubuntu.html

Thing is: The workgroup isn't coming out right:

    $ smbclient -L localhost -U%
    Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 4.1.6-Ubuntu]

            Sharename       Type      Comment
            ---------       ----      -------
            IPC$            IPC       IPC Service (Samba 4.1.6-Ubuntu)
            sysvol          Disk   
            netlogon        Disk  
    Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 4.1.6-Ubuntu]

            Server               Comment
            ---------            -------

            Workgroup            Master
            ---------            -------
            WORKGROUP            MYHOST

But:

    $ cat /etc/samba/smb.conf
    [global]
            workgroup = MYDOMAIN
            realm = mydomain.com
            netbios name = MYHOST
            server role = active directory domain controller
            dns forwarder = 127.0.0.1

    [netlogon]
            path = /var/lib/samba/sysvol/mydomain.com/scripts
            read only = No

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

Can somebody lend me a Clue?

Thanks,
Jim

Well, there are couple of things I can see wrong, one on the howto and 
one in your smb.conf, first the howto:

127.0.0.1 localhost
127.0.1.1 pdc.mydomain.local pdc

10.0.0.5 pdc.mydomain.local pdc

Change it to this:

127.0.0.1 localhost
#127.0.1.1 pdc.mydomain.local pdc

10.0.0.5 pdc.mydomain.local pdc

You are probably using dnsmasq, I would advise you to turn it off

Now your smb.conf

dns forwarder = 127.0.0.1

Change this to:

dns forwarder = 8.8.8.8 # or any other external DNS server

Lets see what happens once your DNS is correct.

I'd already done that, but thanks.

No, I'm not.  I'm running bind9.  The server is also the primary (only,
actually) nameserver on the LAN.  (Or will be.)

BIND is already set up to forward requests for zones for which it's not
authoritative.

I'm confused as to why any of that would affect how smbd advertises
what workgroup it's in?

Thanks,
