In this chapter, we looked at how to use the Active Directory as an identity store, utilizing users and groups on Linux. The ease of setting this up makes this a very usable and much-needed solution within corporations throughout the world.

There is a little bit of ground work required before setting up the time and DNS. Once this is set, then configuring sssd to use Active Directory as an identity source with the command realm is really a doddle.

With the RHEL system in the AD domain, we can manage this domain to a degree with adcli and give users' access to the Linux command line through a console or via SSH.

Next up, we will be staying a little with file sharing, but this time, we will use the Apache HTTPD web server.
