[Samba] Cannot Join Samba 4.1 to an existing Windows 2008 domain as a Backup DC

[Lucas Burdick]

Hi Everybody,
 
I'm stumped. I'm pretty sure I've tried everything to get this to work.  I'm trying to join my CentOS 6 server to my Server 2008 AD Domain.  
 
I'm using SerNet's samba4 packages:
 
[root at files ~]# samba -V
Version 4.1.4-SerNet-RedHat-7.el6
 
I've done the xattr and acl tests and they all come out just fine. So I don't think it has to do with ACLs but I have no idea.
 
I'm also getting LDB errors but I have no idea how to fix them.
 
[root at files ~]# samba-tool domain join MYDOMAIN DC -Uadministrator --realm=MYDOMAIN.COM

Here's what happens when I try to use ntvfs:

Can somebody please point me in the right direction?
 
Thanks!
