Other modules / Re: Zentyal DNS creating and duplicate records problem
« on: December 10, 2024, 12:26:42 pm »
Hi,
Regarding your questions:
1. When you add a DNS record via the Zentyal Web GUI on the Primary DC (e.g., dc01), the record is indeed replicated to the Secondary DC (dc02) as part of Samba’s AD replication process. However, it is expected behavior that the Zentyal Web GUI on the Secondary DC does not display these DNS records. This limitation exists because the Zentyal Web GUI is not designed to query or display replicated records from the Secondary DC. Instead, the Web GUI only shows records that were created or managed directly on the local server.
2. It's important to clarify that a DNS zone and a domain are not the same. A domain in the context of Active Directory is used for organizing users, computers, and other objects, while a DNS zone is part of the DNS infrastructure used for resolving domain names to IP addresses. You can find more information about the difference between DNS zones and domains in this article. https://simpledns.plus/help/definition-domains-vs-zones
In a Samba-managed Active Directory environment, DNS zones are not managed directly through typical BIND files, but rather through Samba tools. If you want to create new zones within a Samba-managed domain, you will need to use tools such as samba-tool to directly manipulate DNS records. https://wiki.samba.org/index.php/DNS_Administration
For the first domain: The Samba + BIND integration manages the domain within Samba (Active Directory) and does not create traditional zone files in BIND.
For the second domain: Zentyal uses BIND to manage the domain, and you can view and edit the DNS zones in the configuration files within /etc/bind/.
3. Domain IP Address usually refers to the IP address of the server that is managing the domain. In this article you can find out what DNS records are and which are the most common ones. https://www.cloudflare.com/learning/dns/dns-records/
Finally, It is not possible to create a domain user with the same name as the system user. This is because there may be internal conflicts, for example, the folder created under the /home directory for the new user already exists, or If both the local and domain user have the same name, there may be confusion about which account is being used when logging in.
Regards,

Other modules / Re: Issue with DNS forwarding
« on: December 10, 2024, 10:56:19 am »
Hi,
Here are a few steps you can take to investigate and potentially resolve the problem:
- Try using a known public DNS server like 8.8.8.8 (Google's DNS):
- Check Zentyal DNS Logs

Directory and Authentication / Re: Configuring Zentyal 8.0 Servers for Realm Sign-Ins (And Basic DC Configuration)
« on: December 04, 2024, 12:03:04 pm »
Hi,
Zentyal uses Samba to perform domain controller (DC) functions. Specifically, Zentyal 8.0 uses Samba 4.15.13, which comes from the official Ubuntu repositories. If your goal is to join a Zentyal server to a domain managed by a Windows server, it is important to consider Samba's recommendations and limitations, as well as the specific version of Samba used by Zentyal.
You can consult the official Samba documentation for more details on how to join a server to a Windows domain.
https://wiki.samba.org/index.php/Joining_a_Windows_Client_or_Server_to_a_Domain
Here is a link to the official documentation on integrating Zentyal with an existing domain:
https://doc.zentyal.org/en/directory.html#joining-zentyal-server-to-an-existing-domain.
Regarding logging into the Zentyal server, it's important to remember that there is a distinction between domain users and groups, and system users and groups. To log into Zentyal as an administrator, you must use a system user that belongs to the sudo group. This is necessary to have administrative privileges within the Linux system on Zentyal.

Installation and Upgrades / Re: Recover login and password for Webadmin
« on: November 15, 2024, 12:54:26 pm »
Hi,
According to the Zentyal documentation, any system user from the sudo group can access the Zentyal interface.
https://doc.zentyal.org/en/installation.html#installation-guide
So you can try to recover your initial user password with the following commands:
If you already have access to the root account or can access the system in recovery mode, log in with root privileges.
Change the system user's password:
If you cannot recover the old user's password, you can create a new user with administrator privileges and add it to the sudo group.
Create a new user:

Installation and Upgrades / Re: Trust between two domains
« on: November 12, 2024, 12:08:34 pm »
Hi,
Currently, Zentyal does not support trust relationships between Active Directory (AD) domains or forests, which limits its ability to establish trust with external domains like those hosted on a Windows Server AD. Zentyal's functionality as a Samba-based domain controller allows it to manage users, groups, and domain policies within its domain but lacks cross-domain trust capability.
For more specific details, you can refer to the Zentyal documentation or Samba's own guidelines regarding limitations in AD support.

- https://wiki.samba.org/index.php/Samba_4.0_Whitepaper

Hi,
In order to make persistent changes to Zentyal configuration files you must use stubs.
https://doc.zentyal.org/en/appendix-c.html#stubs
So you must first create the directory and then copy the stub.

Installation and Upgrades / Re: NIC assignment changes after each reboot
« on: October 08, 2024, 01:48:46 pm »
Hi,
This issue is often a combination of hardware and Linux behavior, rather than a specific flaw in the Zentyal installation. Implementing persistent udev rules is often the most effective solution to ensure that your NICs maintain consistent naming across reboots.
Take a look at the article below because it may help you.

Hi,
With this option selected, you already have access to the desktop while the initial Zentyal installation is running through the wizard. You can launch a console as an administrator and run the following command to monitor the installation progress:
If you notice the process hanging, you can review these log files to identify any messages that might help pinpoint what the system was doing when it stalled.
