samba - Jul 2012 - How do I join a samba 3 client to a samba 4 AD server?

Hi,

I have set up a standard samba4 server via
http://wiki.samba.org/index.php/Samba4/HOWTO and have tested that windows
machines can join the samba4 AD.
Now I am trying to join an Ubuntu machine to the same samba4 ad but it is
failing for me with the following message:

# net ADS JOIN -U Administrator
Enter Administrator's password:
Failed to join domain: failed to lookup DC info for domain
'MYDOMAIN.NET'
over rpc: Invalid server state

The client's smb.conf has the following changed lines from the default
installed smb.conf:
   workgroup = MYDOMAIN
   realm = MYDOMAIN.NET
   security = ADS

The server's smb.conf has the following:
[global]
        server role = active directory domain controller
        workgroup = MYDOMAIN
        realm = mydomain.net
        netbios name = ADSRV
        passdb backend = samba4

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

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

The server's samba4 version is Version 4.0.0beta3-GIT-UNKNOWN
The client's samba version is Version 3.6.3

Hi Quinn

We got a similar message when DNS wasn't working. We added the server IP 
to /etc/hosts and made the server IP the only DNS entry in 
/etc/resolv.conf on the client and we could then join.

Otherwise make sure that
  host server
on the client works.

Good luck,
Steve

Should be posted on the list too...

br,
Quinn
