For demonstrations in this chapter, we will use two virtual machines running in an Oracle VirtualBox virtualization environment.
We have a Microsoft Server 2008R2 Active Directory Domain Controller with the IP address
192.168.0.252 and the RHEL 7.1 host with the IP address
192.168.0.69. This is the same setup that we have used in Chapter 7, Implementing Windows Shares with Samba 4; we have left time and DNS configured the same way. If you are stepping into this chapter without having completed Chapter 7, Implementing Windows Shares with Samba 4, ensure that you have set up the RHEL server to use the Domain Controller for both the time and name resolution.
