[Samba] Joining Samba4 Member to Samba3 Domain

[Jefferson Davis]

Before I start beating my head against the wall, is there a howto someplace
for joining a Samba4 member or BDC to a samba3 domain?  Am I going about
this all wrong?

I most likely will update the PDC to samba 4 next summer due to the amount
of automation we have to modify that leverages OpenLDAP.   The LDAP server
that comes with Samba4 seems kinda limited by comparison.

In the meantime, cannot seem to get Samba4 to join the NT4 domain.

The wiki article on this subject is empty, currently.

Can someone point me in the right direction?

Version 4.3.9-Ubuntu

smb.conf:
