In this setup CentOS 6.5 Desktop will be integrated into Zentyal PDC with the help of Likewise Open package based on Winbind. The instructions also works for Red Hat and Fedora distributions.

Step 1: Integrating CentOS in Zentyal PDC

1. On CentOS 6.5, open a Terminal and login with local root account.

Login to CentOS

2. Open your browser, navigate to the following link and download PowerBroker Identity Services package for CentOS Platform ( x86 or x64 ) and save it.

  1. PowerBroker Identity Services

Alternatively, you can use wget command to download the rpm package as shown below.

# wget http://download.beyondtrust.com/PBISO/8.0.0.2016/linux.rpm.x64/pbis-open-8.0.0.2016.linux.x86_64.rpm.sh

3. Now set the executable permission on the downloaded rpm package by running the following command.

# chmod +x pbis-open-8.0.0.2016.linux.x86_64.rpm.sh

4. Then install Likewise Open software packages needed for CentOS 6.5 to join Zentyal 3.4 PDC by running.

# ./pbis-open-8.0.0.2016.linux.x86_64.rpm.sh

5. Answer all questions with “yes” and after the installation completes reboot your system.

8. Go to IPv4 tab, choose Manual or Automatic (DHCP) address only and enter all DNS configurations needed hit on Apply. On DNS field enter Zentyal Server IP address.

Enter Network Configuration

Enter Network Configuration

9. To verify DNS functionality, issue a ping command on domain name. If domain responds from CentOS, means everything configured correctly.

# ping mydomain.com

10. Next, set hostname for CentOS system in ‘/etc/sysconfig/network‘ file. Here, I set hostname as ‘centos’.

# vi /etc/sysconfig/network

Step 3: Join CentOS to Zentyal PDC

11. Now it’s time to join CentOS 6.5 system to Zentyal PDC to be a part of Active Directory. Open a terminal as root user, and run the following command.

# domainjoin-cli join domain_name domain_administrative_user
Join CentOS to Zentyal PDC

Join CentOS to Zentyal PDC

If you would like to do it from a Graphical User Interface, run the following command on the terminal.

# /opt/likewise/bin/domainjoin-gui

Next, enter Domain settings as shown in the below screen grab.

Enter Domain Settings

Enter Domain Settings

Enter your Zentyal PDC Administrator credentials.

13. As a complementary step you can also confirm from a remote Windows machine by running Active Directory Users and Computers.

After login, reboot your system and your domain will be automatically added to logins. Then you can perform login just using the remote username without the domain name.

Enter Login User

Enter Login User

User Shell Login

User Shell Login

16. Now you can login on CentOS with remote users belonging to Zentyal PDC Active Directory and their default profile will be stored under.

/home/local/DOMAIN_NAME/domain_user
User Profile Paths

User Profile Paths

17. To remote login from Putty use this login structure.

domain_name\domain_user

If you like to change that ugly “sh” prompt switch to bash shell.

/bin/bash
User Shell

Step 5: Enable Active Directory Administrative Rights

18. By default CentOS doesn’t allow remote users from Active Directory to perform administrative tasks on system or to empower the root account with sudo.

Enable AD Rights

Enable AD Rights

19. To enable Active Directory Administrative rights on User, you need to add the user to sudoers file.

# vi /etc/sudoers

OR

# sudo visudo

Add the following lines with your Zentyal Administrative user as shown below.

DOMAIN_NAME\domain_administrative_user    ALL=(ALL)  ALL

domain_administrative_user    ALL=(ALL)  ALL
Add Administrative Rights

Add Administrative Rights

20. As demonstrated now Zentyal PDC Administrative User has full root privileges install/remove software packages, manage services, edit configuration and much more.
