Hm,, why is this server resolvng outside the domain your joining? 
I would have expected :  
40.176.192.131.in-addr.arpa domain name pointer sambaDC.domain.com 

But not a .local 
Did you start with DHCP ip and changed it later on maybe?

Ok, thats a line i might have missed in the late changes for the join i gave. 
You need at least one of these 2: 
Set in /etc/hosts the correct hostname and ip for the server. 
And/or Set in the DC the hostname and ip ( so A/AAAA and PTR ) record. 

Normaly, we set the /etc/hosts file and the A records is automaticly created by join. 
Manual check the PTR after a join.

Yeah, understandable.  
And also remember, you might be able to join correclty and be unable replicate the AD due to the Exchange schema. 

I'll go test a DC join tomorrow on a MS W2008 server. 
I'll keep you posted when its done. 


Greetz,
