How do I authenticate Samba with Active Directory?

Set up smb.conf.Set up krb5.conf.Set the authentication method.Check the connection to make sure it works with the Windows Directory server active.Check authentication.Configure the portal user authentication method on.

While experimenting with setting up 4 samba as the giant PDC controller (primary domain) of their newly created EXAMPLE-Domain.COM domain, I naturally wanted to test whether clients could connect to a windows server independent from a managed Samba 4. domain.


The configuration is not very confusing. Since this is a test build for my own learning only, it might still be in the spectrum had samba installed in the container Ubuntu lxc running under 20.04. Whether the domain file was still set to EXAMPLE.COM, the domain file is definitely Samba was often set up for machines according to the official documentation and the Ubuntu plus manual (very good at distinguishing between systemd module files!).

What is a samba domain member?

a is a domain-joined Linux computer running Samba that does not provide Internet Domain Services such as an NT4 elementary domain controller (PDC) or a Directory active (AD) domain controller (DC). On a real member of a Samba domain, you can:

The blog controller was installed using the incredibly simple samba tool’s domain deployment command, unless you have special settings.

The Windows Client was installed by running the virtual machine (using VMware Player) and connecting to the hard physical work network.


It’s definitely worth mentioning that I ran into the problem that the Ubuntu LXC container was not started using my fixed IP address, (in the specific container config file), but significantly with a DHCP address. This appears to be caused by a problem in the current netplan IP configuration package. This turned out to be fixed, but the DHCP address was also intercepted. So for a while, and only during domain preparation, the temporary ubuntu container had two IPs configured. Why a person is important, will soon find out.

Windows 7 Cannot Join The SAMPLE Domain

How do you fix the following error occurred attempting to join the domain?

enable SMB1 support. You press the Windows key R + to open Run.Check a third-party antivirus program. It is understood that the above error is caused by third-party anti-virus programs.Use a system restore point. Type recovery in the system search bar.

After the windows 7 client has been installed normally, it’s time to change the software settings to join the domain computer to the domain.

However, your first attempt failed because the EXAMPLE domain type was still not found. Indeed, some Windows machines received DNS servers, such as the DHCP server, neighboring DNS servers and 8.8. 8.8 defined. To be able to join a location, the client domain controller must use it as a DNS server.


The next attempt to login to the domain always failed with the following error:

error in domain join verification samba

The following error occurred while connecting to the “EXAMPLE” domain: Connection failed: unknown username or invalid password.

In order to join a domain, I need the credentials of the “Administrator” user. The error is saying that this password is incorrect, but the password must be checked three times and must be correct. You can check this by accessing the Netlogon share on the domain controller in Intarnet.become:

[email protected]:~# smbclient //localhost/netlogon -UAdministrator -c ‘ls’
EXAMPLEenter administrator password: [password entered]

Log Analysis

My first thought was that it could very well be a DNS server issue with Samba (the INTERNAL_DNS backend). Maybe I would say that the machine is not registered, is it true that you cannot create a DNS server on the internal surface in Samba?

After planning = log level 3 in /etc/samba/smb.conf (global other section) the domain should be tested by joining. It turned out that in /var/log/samba/log.samba there was an output:

How do you solve domain problems?

check DNS connection The computer may still be using the wrong DNS server or not using it at all. Make sure this server name entry in /etc/resolv. conf becomes the IP address of a DNS server capable of resolving the domain tag you want to join . The IP address is assumed to belong to one of your domain controllers.

The resulting Samba domain has Kerberos queries through a Windows client (using DHCP, look for Owner authentication worked fine (NT_STATUS_OK) but could end up with NT_STATUS_CONNECTION_DISCONNECTED. No real error indicates that what probably caused this. However, Windows then made two more attempts to access the then site name, stopped, and finally displayed the usually familiar error message.

Why did Samba fail to find DC for domain samdom-undetermined?

When a host is joined (advertised) to Active Directory, the Net command fails to find a Samba domain controller (dc): uses DNS lookups and broadcasts to find domain controllers when joining the world. Both methods don’t work, you just get an error. not found domain controller for SAMDOM domain – Unknown error.
