samba - Jul 2013 - Joining Samba4 as DC--Error Failed to find a writeable DC for domain

Dear all,
I set up samba 4.1 (SlaveDC)in a test environment on CentOs 6.4.
I tried to join this host to my running and provisioned MasterDC (Samba
4/CentOs 6.4).
On the SlaveDC I did :  samba-tool domain join tplk.loc DC -Uadministrator
--realm=tplk.loc --dns-backend=BIND9_DLZ
It gives me:
[root at s4slave ~]# samba-tool domain join tplk.loc DC -Uadministrator
--realm=tplk.loc --dns-backend=BIND9_DLZ
Finding a writeable DC for domain 'tplk.loc'
ERROR(exception): uncaught exception - Failed to find a writeable DC for

    raise Exception("Failed to find a writeable DC for domain

domain)

Do I miss something?Just pulled with git, configure, make, make install, no
porovisioning, just domain join!???

Just did the trick:
Put the nameserver MasterDC in my /etc/resolv.conf on the SlaveDC
and all is finished.
