How to Join CentOS 7 Computer to an Active Directory Domain

Add BeyondTrust AD Bridge Open repository to your system.

sudo wget -O /etc/yum.repos.d/pbiso.repo http://repo.pbis.beyondtrust.com/yum/pbiso.repo

Once your Repository has been added, you can then install the BeyondTrust AD Bridge using the following commands.

sudo yum clean all
sudo yum install -y pbis-open

Do the following customization.

# Set domain prefix
sudo /opt/pbis/bin/config UserDomainPrefix <DOMAIN NETBIOS NAME>

Ex: 
sudo /opt/pbis/bin/config UserDomainPrefix EXAMPLE

# Set default logon domain
sudo /opt/pbis/bin/config AssumeDefaultDomain True

# Set default login shell
sudo /opt/pbis/bin/config LoginShellTemplate /bin/bash

# Set home directory template
sudo /opt/pbis/bin/config HomeDirTemplate %H/%D/%U

Join the computer to the domain.

sudo domainjoin-cli join <DOMAIN NETBIOS NAME> <DOMAIN ADMIN USERNAME>

Ex: 
sudo domainjoin-cli join EXAMPLE.LOCAL yasithab

Add domain user to the sudoers group.

sudo usermod -a -G sudo <DOMAIN USER>

Ex:
sudo usermod -a -G sudo shashikaj

Allow the above domain user to run sudo commands without entering the password.

# User rules for Domain User
<DOMAIN USER> ALL=(ALL) NOPASSWD:ALL

Ex:
shashikaj ALL=(ALL) NOPASSWD:ALL

In order to get domain information, run the following command.

sudo domainjoin-cli query

tip

If you want to remove your computer from the domain, you need to run:

sudo domainjoin-cli leave
