I want to create another DC in my network. Today, my DC is Debian 7 with Samba 4.2.1 compiled (source package). Are ther problem if I install another DC with Debian 8 and Samba 4.1.17 (apt-get -t backports)? I will follow the tutorial below: https://wiki.samba.org/index.php/Join_a_domain_as_a_DC Regards, Márcio
