samba - Jan 2014 - Can not join samba4 to a windows 2012 server with a 2008R2 schema

Hello,

I am tring to get my samba 4 machine to join a windows2012 Domain as an 
additional DC for a remote site i need to setup.
In my test setup samba 4 fails to join. I have googled, but i am trying 
it for about a week now so it is time to call someone. :)

My setup is FreeBSD 10 with samba 4.0.13, but i also tried FreeBSD 8 and 
9 with the same result.
My windows 2012 server is provisioned with a 2008R2 AD and functionality.
Could some one please point me in the right direction?

The error i get is as follows.
