Being able to manage the Active Directory group membership is fundamental to our management of Linux. We can assign the ownership of files and directories to these groups and (more importantly) the delegate rights on the system using the /etc/sudoers file.

Let's see how this delegation works. We will create a new group in the Active Directory and add an administrator to this group. As a simple setup, we are limited to users that we have created, as shown in the following commands:

$ adcli create-group  --domain=example.com \ --domain-ou="OU=Linux,DC=example,dc=com" "Linux Admins"
$ adcli add-member  --domain=example.com "Linux Admins" Administrator

This file can be used as delegation, which allows selected commands to be run as root by selected users. These commands...
