WSL2 is Windows Subsystem for Linux 2. Its VM which is light weight and uses latest and best virtualization technology to run a lightweight Linux kernel image inside windows 10 machine.

Installation of WSL2 is very straight forward and took three or four clicks to get it started.

WSL2 Architecture Design in Windows 10 !!

VMs of Hyper-V/Virtual Box and VMWare player can be slow while booting up as they are more resource hungry. In short other VMs require great efforts to manage and full technical skills but WSL2 provide light weight VM which is created behind the scenes.

Default Path of WSL2 installation: “C:\Users\user_name\AppData\Local\Packages\”

Eventually WSL2 has all the features available under WSL1 version and it can runs with current versions of VMware and VirtualBox. Integration between Windows and Linux machine is same as WSL1.

Procedure to fix the issue of “error related to the WSL” :-

Time needed: 2 minutes.

We have fixed same error by following below method. Simple steps can be followed by anyone to get it resolved by yourself.

Move existing WSL2 installation to D: drive | WSL2’s ext4.vhdx file default path change

WSL2 by default installed in C: drive and there is no straight forward option to move it to different driver. In below video we have successfully move ext4.vhdx file to D: drive by modifying one registry key. Channing registry is very technical thing so make sure you take backup before making any change.

Registry Path for WSL2 installation. Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lxss\

We need to change Basepath location to D: drive after moving the ext4.vhdx file to D: drive.

Default location of WSL2 installation is c:\ drive. Example path:- C:\Users\sonooskb\AppData\Local\Packages\TheDebianProject.DebianGNULinux_76v4gfsz19hv4\LocalState

How to Join Ubuntu 22.04 with Active Directory

Process for Domain Join Ubuntu 22.04 with Active Directory is very easy and straight forward. Ubuntu 22.04 is latest version of Ubuntu which is come along with lots of new features and enhanced user interface. Earlier integration of Ubuntu with Windows Active Directory is very limited to login process only. Now with latest version of Ubuntu we can do more than login process like applying group policy with Adsys.

Here is step by step process in which we can learn how to join Ubuntu 22.04 with windows active directory. We have used sssd and realmd module to join ubuntu 22.04 with active directory.

How to apply Group Policy on Ubuntu 22.04?

Installation commands to support join AD

Note: Make sure DNS settings are correct before starting the process. DNS IP address of Ubuntu 22.04 should be IP address of Active Directory Server. Ping both the machines from each other to test the connectivity. Time should be matched on both the machines.

$ sudo apt update

Installation of packages required for domain joining of Ubuntu

$ sudo apt install sssd-ad sssd-tools realmd adcli

Check and verify the installed packages of sssd/realmd/adcli

$ apt policy sssd-ad sssd-tools realmd adcli

Check and Join domain with Ubuntu

Note: srv2019.sonoos.kb is server name of Windows Server 2019. Domain name sonoos.kb used in demo

$ realm discover srv2019.sonoos.kb

Joining Ubuntu to AD by using realm command

$ sudo realm join srv2019.sonoos.kb

Checking Domain joining status of Ubuntu using sssd.conf file

$ sudo nano /etc/sssd/sssd.conf

Run below command to create home directory when AD user login on Ubuntu

$ sudo pam-auth-update –enable mkhomedir

Checking domain joined or not by Ubuntu machine by following command.

$ sudo realm list

getent command to test AD user on Ubuntu

$ getent passwd sysadmin@sonoos.kb

Now you can try to login on Ubuntu using your AD credentials. Just reboot the system or switch users to login.

How to apply Group Policy on Ubuntu 22.04?

After release of Ubuntu 22.04 in April 2022, Ubuntu and Microsoft are now supporting the much awaited feature of Applying Group Policy on Ubuntu 22.04. Now joining Active Directory by Ubuntu 22.04 is made easy and also supporting offline login by the AD user in Ubuntu 22.04. Our previous article on Active Directory Joining by Ubuntu is very much appreciated by the community.

There are three prerequisite to apply Group Policy on Ubuntu 22.04.

First prerequisite is join Ubuntu to Active Directory.

Second is Adsys client installation on Ubuntu client machines.

Third is Ubuntu Advantage subscription for the privilege management and remote scripts execution features.

Finally we need not to install anything on Windows Server to support GPO on Ubuntu except adml and admx file import to support GPMC template for Ubuntu.

How to install Ubuntu 22.10 on WSL in Windows 11

Packages to be install on Ubuntu 22.04

Following package are required by Ubuntu client machine to support Active Directory integration with Ubuntu 22.04.

Adsys
SSSD

sudo apt update

Installing SSSD and its required packages:-

sudo apt install sssd-ad sssd-tools realmd adcli

Installing Adsys:-

sudo apt install adsys

Time needed: 10 minutes.

After installing SSSD and Adsys. Let us look at the below method to verify, join and apply GPO on Ubuntu 22.04:-

Verify ping and port connectivity with Active Directory Domain Controller system from Ubuntu client machine
telnet srv2019.sonoos.kb 389
ping sonoos.kb
LDAP TCP – 389
LDAP for Global Catalog TCP- 3268
SAM/LSA TCP – 445
W32Time NTP UDP – 123
DNS – TCP and UDP 53
Kerberos V5 UDP- 88
Use realm discover command to discover Domain Controller | Domain Controller Name: srv2019 | Domain Name: sonoos.kb
realm discover srv2019.sonoos.kb
Use realm join command to join Window Active Directory Domain | Domain Controller Name: srv2019 | Domain Name: sonoos.kb
sudo realm join srv2019.sonoos.kb
Provide Windows Server Domain administrator account password to join AD.
Verify sssd.conf file for domain join status of Ubuntu client machine.
sudo nano /etc/sssd/sssd.conf
It is successful join if output contains information about your domain, nss and pam.
Create Home directory of ubuntu active directory account/user by pam-auth command
sudo pam-auth-update –enable mkhomedir
Now go to Domain Controller and verify that computer name of Ubuntu is added in Computer OU in Active Directory Users and Computers.
If computer account for Ubuntu client machine has been created now try to log on Ubuntu Client machine with domain user like in my demo i have used bob@sonoos.kb
After successfully login of AD account on Ubuntu verify pwd and whoami command output.
Now its time to configure group policy for ubuntu client machine, follow above mentioned command to install GPO client:

sudo apt install adsys
Verify realm list before applying GPO on Ubuntu Client | Output should contains information related to your domain
sudo realm list
To generate admx and adml file for Ubuntu run following command in terminal:-
adsysctl policy admx all
Now two file will be created on current directory (Ubuntu.admx and Ubuntu.adml).
Move both files to Domain Controller. Paste file Ubuntu.admx file to \sysvol\domain\policies\policydefinitions folder of domain controller. Paste Ubuntu.adml to \sysvol\domain\policies\policydefinitions\en-US folder.
Now its time to apply first group policy on ubuntu. Move your Ubuntu Client Computer Name to New OU (Ubuntu Clients) in AD Server. After moving computer account to new OU. Go to GPMC.msc and link new GPO.
Now after linking new GPO on Ubuntu Client OU.
In this step we are providing sudoers permissions to normal AD users for Ubuntu login via GPO setting Client Administrators.
Let us use command to push group policy on Ubuntu.
adsysctl policy update -av
Verify GPO applied on Ubuntu with command:-
adsysctl policy update –details
Now login again with AD user bob@sonoos.kb in Ubuntu client and see, bob has all the sudoers permissions.
