How to join Ubuntu 8.04 to Windows Active Directory (Domain)
Posted May 23, 2008on:
These days many more companies are using mixed IT enviroments using a mixture of Windows, Linux, UNIX and Mac’s and I for one am using a mixture of Microsoft Windows and Linux (Ubuntu). On my network I use a Microsoft Active Directory and want to be able to get all Server (Linux & Windows) as well as Desktops (Linux and Windows) to authenticate in a central location.
Since browsing the web I managed to find this cool package that can be installed on Ubuntu Hardy Heron (8.04) which enables you to add and authenticate Ubuntu 8.04 against a Windows Domain Controller (Microsoft Active Directory)
So here goes…
sudo apt-get update
sudo apt-get install likewise-open
sudo domainjoin-cli join fqdn.of.your.domain Administrator
sudo update-rc.d likewise-open defaults
sudo /etc/init.d/likewise-open start
Using the above commands you have installed ‘likewise-open’ which is the package that makes it possible for the Ubuntu client/server to logon to a Windows domain, added the client/server to the windows domain, updated the system services and then started the service.
Now that the LikeWise package has been installed you can now logoff (although I recommend full system reboot) and logon in this format:
You need to ensure that you prefix the username with the Domain name.
The good points about this kind of setup is as follows:
- Single username/password combination across entire network.
- Enforces password policys
- Likewise Open enables Linux, Unix and Mac authentication on a Microsoft network using Active Directory. A user can now interactively log in to the Linux, Unix or Mac machine using Active Directory credentials, and can access any kerberized services that the non-Windows machine hosts.
