This series will be titled Preparation for the setting up and managing Zentyal as PDC (Primary Domain Controller) through Parts 1-14 and covers the following topics.

Part 1: Install Zentyal as PDC (Primary Domain Controller) and Integrate Windows System

This tutorial will demonstrate how to use a Linux distribution, Zentyal, as a PDC ( Primary Domain Controller ) and integrate a Windows-based system in this Domain Controller.

Requirements:

  • Download Zentyal Server Development Edition 7.0.
  • A different computer that runs a Windows-based system to be integrated into the domain.
  • The domain used is a fictional one and runs on a local network only: “tecmint.com”.

Step 1: Installing Zentyal Server

1. Choose language.

7. The next installer stage is to set the hostname for your system. You should enter here your FQDN. This is a test server so I choose “pdc.tecmint.com” ( Be aware that “pdc” will be this server and “tecmint.com” would be your domain for Active Directory ).

Choose Zentyal Hostname
Choose Zentyal Hostname

8. Next choose a user for system administration ( This will be the privileged user with root powers – sudo ) not the user domain controller.

Set Zentyal User

9. Next type a password for the sudo user. Choose a strong one ( 9 characters at least upper&lower&numerical&special ). Here I choose a simple one because is a test server.

10. Next it will ask you to re-enter your password and if you choose a weak one the installer will warn you about this fact. So select Yes and hit enter.

11. Next step is configuring your time. If your system is connected to the Internet the installer will automatically detect your time zone. So press Yes if your time setting is the correct one.

15. Configuring the Hard Disk Partitions. My HDD system config is the following.

  • 40 GB for / Partition ext4
  • 1 GB for swap area
  • 10 GB for /home ext4

On a real server, you should allocate more space for all of the partitions, even create a new one for /var partition. Now is the time to create a partition. Follow the steps. Choose Free space.

Choose Free Space

16. The next stage on the installer is asking if you want to set up a Graphical Environment for Zentyal. If your server has a monitor and a keyboard attached to it then you should probably choose No ( This will install an LXDE GUI ) else choose yes ( you will control your system remotely using a web admin interface and ssh ).

Choose Zentyal Graphical Environment

Step 2: Installing Basic Softwares for PDC

22. Now it’s time to go to heavy stuff – meaning accessing web remote administrating tool and installing the basic software for the server to become a complete Primary Domain Controller (PDC) with samba4.

  • Next, open a web browser and type the address prompted in Zentyal ( for this example the web admin address is : https://192.168.0.127:8443 ).
  • Next, the web browser will warn you about a security issue relating to the certificate.

23. Choose “Advanced” and then “Proceed” like in the screenshots below.

24. Then enter your user and password for the admin user ( the user-created on installation).

Zentyal Admin Login

25. We are now presented with the Zentyal Web Administration and it’s time to choose and install software for our PDC from Software ManagementZentyal Components and choose the following packages (modules) for the server to become a Primary Domain Controller.

  • DNS Service
  • Domain Controller and File Sharing
  • Firewall
  • Network Configuration

26. Next, go to the SystemGeneral and set the Hostname and Domain.

That’s it for now on the PDC server minimal configuration to become a Primary Domain Controller.

Step 3: Integrating a Windows System in PDC

It’s time to integrate a Windows-based system ( In this example a Windows 10 system) in the “tecmint.com” domain.

31. First let’s set up the network configuration for the system to be able to access the new domain. Go to Start -> Control Panel -> Network and Internet -> Network and Sharing Center -> View Network Status and Tasks -> Local Area Connection.

On Local Area Connection select Properties -> IPv4 -> and enter your static IP, netmask, gateway, and DNS like in the screenshots below.

Configure IP Address in Windows

32. To be sure that everything is OK try first pinging your pdc server address and then ping the domain name.

Ping Zentyal PDC Domain

33. We now reach the end of this tutorial. Let’s finish the configuration by adding Windows 10 to the tecmint.com domain name. Click “Computer” -> System Properties -> Advanced System Settings -> Computer Name.

Enter your computer name in the Computer Name field domain in Member of Domain.

Add Windows to Domain

34. On the next prompt enter username and password for the Administrator User of your domain ( the user created in Users and Computer through Zentyal Web Interface).

Congratulations! You now have a full domain service and you can easily add other windows based systems into your new domain.

The next tutorial will be on how to access your PDC server remotely from Windows-based systems, Create new Users and Groups, Create a Share, and set up Group Policy for this domain users and computers.

  1. Please do not refer to any Samba AD DC as a PDC, it isn’t. A PDC is the Primary Domain Controller in an NT4-style domain. Whilst one AD DC will hold the PDC_Emulator FSMO role, this can be any AD DC, using terms such as ‘first’ DC can be used, but are a bit meaningless if that DC is later demoted.

  2. This works great but the only issue I’m running into is when a user tries to change his or her password from the windows computer, it says incorrect user/password. If that can be figured out, this will be really useful for me.

    • Maybe the passwords they enter don’t meet the security requirements for your domain. Provide more details? Can you change a user password from RSAT? What about from Zentyal panel?

    • You can join differnet OSes to Zentyal pdc, but windows GPO applies only to Windows based workstations. I dont’t think there’s a windows GPO echivalent on Linux or mac.

  5. I followed every single step in it TO THE LETTER and Windows clients still refuse to join the domain. You will get it all set up (which takes hours to load and configure), only to attempt to join your client to the domain and get the error message: “The following error occurred attempting to join the domain ‘YOURDOMAIN’ The specified domain either does not exist or could not be contacted.” Zentyal is a complete failure and is totally unable to act as a Primary Domain Controller for Windows clients.

  6. Hey Matei Cezar, I am currently using Zentyal 4.2 as a PDC and able to connect Windows client. However, I am facing issues whilst pushing GPO’s to the multiple users/groups. I could see few settings are getting updated at the client end but most of the important ones are missing out; I have tried logging in with multiple ID’s on multiple system’s but no joy; I believe there’s a communication issue with Widows/Zentyal. Any help would be greatly appreciated.

  7. @Rully: First of all the second computer must be joined to Zentyal PDC from an administrative account. What do you mean an existing account bla bla bla…it has importance all the displayed error message it shows you! It could mean that you have another computer with the same name on your network!
    How much NICs your server has? You must fill the external interface with all the required internet settings provided by your ISP, not jot the IP Address. (put IP, Netmask, Router (gateway) and DNS! You must also check the outgoing rules from firewall.

  8. Dear Matei Cezar,

    I need help please…I have install Zentyal 4.0 in my office server. And I try connecting the client to the server. I use my computer and it’s connected to the zentyal server. but when I use other computer it always said “The join operation was not successful, this could be because an existing computer account…bla..bla…could you please tell me what is wrong with that?

    And one more thing I have public IP from my Internet provider and I want to set the zentyal to be access remotely but when I fill in the ip number to the network setting on zentyal server why I still can’t go online and open a website on the browser.
