Today I like to introduce our new Domain Join Assistant for Univention Corporate Server (UCS). With the new tool, administrators can integrate Ubuntu computers into a UCS domain without any additional manual configuration effort. Thanks to this, all users can log in directly to their Ubuntu desktop using their usual domain accounts. With this automation, we want to make it much easier for administrators to manage Ubuntu clients on the network. Thanks to Kerberos SAML integration, organizations that already use UCS version 4.3, which was released a few weeks ago, can now offer their users single sign-on for the Ubuntu clients.

Please note that the new Domain Join Assistant will also replace the previous Univention Corporate Client (UCC), which we will discontinue. However, customers with a maintenance contract for Univention Corporate Client will receive UCC updates until April 30, 2021.

We want to give all UCS users the possibility to easily integrate notebooks and PCs with standard Ubuntu into their UCS domains, thus keeping the maintenance effort as low as possible. The new Domain Join Assistant will be of great help for this.

Other benefits of the Domain Join Assistant in UCS environments

• Users can log in to various Ubuntu systems using their login information.
• Manual login is no longer required, because users can enter their credentials in the clear user interface and all subsequent steps are done automatically.
• Users can work without the installation of a special client.

Support for Ubuntu clients up to version 18.04

Univention supports Ubuntu 17.10 (“Artful”), 16.04 LTS (“Xenial”) as well as the brand new Ubuntu 18.04 LTS (“Bionic Beaver”) that is expected at the end of April.

Find more information and a download guide for the Domain Join Assistant on Github.

If you are a maintenance customer of Univention Corporate Client (UCC), please find more information on the discontinuation in our Univention Wiki .

Maren Abatielos joined Univention in 2012. Since then she has been engaged in content and social media marketing for UCS and Open Source in general.

  1. This is a great effort from UCS. But what about the admin account not being the root of the client machine? (Just like in Windows system).

      Hello Sharif,

      Our current main focus is to enable the domain registration for Ubuntu clients in UCS. This should work ideally with only a few adaptions of the Ubuntu base, so that after the installation of new Ubuntu updates, everything else will also work perfectly.

      If you want to use the admin account in Ubuntu, you could add the user ‘Administrator’ to the group ‘sudo’ on your Ubuntu client.

      If you have any further technical questions, please visit our forum Help where you find many other UCS users whith plenty of experiences as well as partners and my colleagues of the support team.

      Hi Antonio,

      The actual focus of our development is to enable the domain registration of Ubuntu clients in UCS with only very few adaptions of the Ubuntu base. At the moment, we do not plan any other extended features, because our core business is Univention Corporate Server. So if you have any special requests, please use the existing Ubuntu tools.

      If you have any further technical questions, best you visit our forum Help where you find many other UCS users with plenty of experiences as well as partners and our support team.
