The Corona crisis has had a huge impact on our society. Office workers had to start working remotely, medical professionals had countless double shifts and delivery companies went into over drive. Winners and losers everywhere – Amazon grew turnover by 25% in the second quarter of 2020, the cloud computing department of Microsoft saw a 47% growth, we all know Zoom barely held it together, spending hundreds of millions on expanding their server farms.
EGroupware is a team management solution which specialises in team communication. The software is not only open source-based, but can be easily integrated into existing IT infrastructures. EGroupware can be installed via the Univention App Center.
The great advantage of Univention Corporate Server lies in the integrated identity and infrastructure management system. This facilitates the administration of applications, users and resources. Userscan, for example, simply install a mail server or other additional components that connect seamlessly with EGroupware.
Due to the ongoing corona crisis and the resulting increased demand for home office support, EGroupware has brought forward features originally planned for version 20.1 and released it already in April 2020.
Connecting Ubuntu and Linux Mint Clients to UCS Domains: New Version of the Univention Domain Join Assistant
The tool offers a graphical user interface and a command line tool for admins who prefer to work on the shell. We have just released a new version of the Domain Join Assistant that comes with various improvements and supports the latest Ubuntu and Linux Mint versions. In this article I’m going to show you how the tool works and I’m going to introduce the new features.
SURF is the cooperative association of Dutch educational and research institutions. One of the goals of our organization is to facilitate research with HPC (High Performance Computing). We run national super computer clusters and provide computing power, data transport, data management and analysis for the Dutch academic community, i.e. to universities, universities of applied science, senior secondary vocational institutions (MBO), UMCs and research institutions.
Certificates – Why and What for
In this article I would like to give you an insight into the topic “Securing the Internet-based exchange of information through certificates”. I’ll take a quick look back at the beginnings of the Internet and the use of protocols such as HTTP, SMTP, POP … and their encrypted transport via SSL or TLS. Above all, however, I would like to explain to you how you can use public certificates with Univention Corporate Server to secure your data transfer or also how you can create trustworthy certificates by yourself with Let’s Encrypt. Completely secure and free of charge on top.

Digital Sovereignty is an Indispensable Prerequisite for the Resilience of Our IT Systems – First Lessons from the Corona Crisis
We are in the transition to a “new normal”. However it will look different from the normality before the corona pandemic. Step by step areas of life are being ramped up that until recently were in an unprecedented exceptional situation. This involved a lot of stresses, but it has also brought new and valuable insights into how we can organize our lives. The significance of digital communication options has increased enormously. The use of digital technologies has been accelerated tremendously. It became clear that it is important to have systems that function independently of individual providers or even of foreign countries. Systems that are resilient and can react quickly and effectively to a crisis so that stable conditions can be restored.
The two authentication standards SAML (Security Assertion Markup Language) and OpenID Connect have already been available to UCS users for some time. So far, however, these two technologies have been two separated worlds. If some of the web services used SAML and others OpenID Connect for the authentication against UCS’ identity management, users were forced to log in twice in those environments with multiple services. With the support of the Kopano team, we were able to release an extension of the app “OpenID Connect ID” in the App Center. This is integrating the two standards with each other and thus allows a single authentication process by the end user.
I would like to briefly explain how a single sign-on generally works with UCS. Then I explain the interaction of Kerberos, SAML, and OpenID Connect and show you which functions the new implementation of Kopano Konnect offers to UCS users.
