Setup of an Efficient IT Infrastructure with Central Identity Management in 261 schools in Cologne

A large-scale project is currently under way in Cologne, Germany: the setup of a standardized, centralized identity infrastructure for all schools. This is set to include considerable simplification of the software distribution and the administration via the education authority over the coming years and measures to ensure that the schools in Cologne are ready for the digitalization of education.

MediaWiki – a Culture of Sharing Your Knowledge

Bild von alten Büchern

Enterprise wikis are about technology and features – but also about the main principle of sharing.

Wikis were a small cultural revolution. The idea behind it: Different people join online to collaboratively write texts, review them, discuss changes, improve, supplement, link and categorize them. And through this work and combined knowledge of many people a powerful central knowledge base is created in which you almost always find what you need to know.

Wikipedia has consistently thought through the model of openly exchanging knowledge and made it popular. For 17 years Wikipedia has been the place to go for knowledge on the Web while the use of wikis has been spreading in companies, too. The open source software TWiki (1998) or the proprietary Confluence (2004) paved the way for the triumphant march of wiki technology in companies. Of course, the Wikipedia software MediaWiki (2002) also plays a part in the story about wikis in companies. But more on that in a moment.

Guide to Your Private UCS Server with ownCloud, Kopano & Let’s Encrypt

Have you ever thought?: “It’s enough! I finally want to set up my own robust, powerful server at home to put an end to the permanent threat that someone might hack my precious data.”

I did! And today, I’d like to share with you here all the necessary steps that are required for this. In addition to UCS, my home server scenario also includes a software bundle made up of groupware, mail, and file exchange software, i.e. ownCloud and the Kopano apps. This bundle make proprietary mail and groupware solutions redundant if you like. In addition, I also show you how to install Let’s Encrypt so that the connections to your UCS server will be well protected, too.

New Domain Join Assistant Allows Foolproof Integration of Ubuntu Clients into UCS Domains

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.

LDAP/OpenLDAP: The Two Pillars in UCS’ Identity & Access Management

LDAP

Our work environment is becoming more ‘colorful’, but also more difficult to handle and control. Employees increasingly determine for themselves which tools they use and where they work. As an admin, you easily lose track and become afraid of losing control over the security of your corporate IT.

Fortunately, UCS provides an identity and access management (IAM) that centrally manages and supervises all tools, devices, data, and accesses. By setting up a centralized IAM, you not only avoid shadow IT, but most of all, you regain control over your network and your precious data.

For those of you who have little technical knowledge in UCS, I like to explain today the terms LDAP / OpenLDAP, as they are the cornerstones of our central IAM system.

Would you like some valuable tips on how to increase network performance and user data availability when using Windows clients together with UCS?

Thinking about user data, many of us admins immediately understand that questions about the issues of backups, privacy, and availability, no matter whether across different machines or outside the office, can create us a considerable headache. But fortunately there are solutions in place and in this article I want to cover two of them.

SchwuZ Keller

Short Introduction: How to Upgrade Your E-mail Server to a Bullet-Proof Fortress

E-mails have become an integral part in our everyday lives. In business anyway, but they have also found their way into our schools. However, schools face the same problems that have long been known by organizations: School authorities with thousands of students, hundreds of teachers and many administrative employees offer hackers a target at least as worthwhile as other large enterprises.

In this article, I’ll show you some simple yet highly effective measures that you as the administrator of a corporate IT or school IT can take to effectively protect your users and mail servers from hacker attacks. As massive spams are not only annoying or even dangerous to us all, they can also cause other mail servers to mistrust your email servers so that your users will no longer be able to send regular mails.

End of Maintenance of UCS 4.1

The regular maintenance of UCS 4.1 ended at April 5th.

Users who still using UCS 4.1 should update to a more current version of UCS to get further security updates, bugfixes and minor-releases. To update to UCS 4.3 you have to change to UCS 4.2 first. A description of the necessary steps to update you could find in the release notes of UCS 4.2.
