[Samba] Help setting up global catalog

[mf_in_mun at hotmail.de]

Hallo,

i've just setup a Samba4 beta7 on a centos 6.3 with bind 9.8.2.
I followed the instructions at http://wiki.samba.org/index.php/Samba4/HOWTO
It's up and running.
But when I add a user on the Windows 7 AD console, I got a message that 
there is no global catalog.

I'm realy sorry, but after some hours googling around, I don't have any 
idea to solve that problem.

Some help would be realy appriciated.

Regards

Sebastian Mißfeldt
