“Kopano to go, please!”

…or: How do I set up my own mail and communication server in just 30 minutes? That’s the question I asked myself when my daughter got her first smartphone and asked for an e-mail address. I needed something which was easy to use (I’m no Linux whiz) and compatible with both the web and smartphones, which also allowed me as a parent to retain some degree of control.

I published the following article on my own blog on August 13, 2016. And because what’s good for families with daughters of course can’t be bad for companies either, my colleagues at Univention thought it would be worth publishing here too.

Brief Introduction: Bring Your Own Device (BYOD)

Bring Your own Device Illustration

The term “bring your own device” also known by the acronyms “BYOD” and “BYOT” refers to the concept of organizations and companies allowing their employees to bring their private, mobile devices to the office and use them. This can present a number of advantages for both employees and organizations alike, for example:

  • Potential for cost savings on devices from the organization’s perspective
  • Employee satisfaction at being able to choose the device freely
  • Simplification of the work/life balance for employees
  • Increased productivity from not being bound to specific locations and schedules

In addition to the advantages listed above, the development also goes hand in hand with a whole range of legal, organizational, and technical challenges.

How can OpenLDAP with UCS be scaled to over 30 million objects?

The majority of the environments in which UCS is employed include anywhere from a couple of dozen users up to several thousand – sizes which can be directly implemented with the standard configuration of UCS. In the systems operated by the education authorities we see a leap to between 10,000 and 100,000 users – in this case, the UCS@school concepts allow functioning scaling.

Even including groups, hosts, and other LDAP infrastructure objects in the calculations, these environments rarely exceed 200,000 objects. But what happens when an environment with more than 30,000,000 objects needs to be administrated in LDAP?

UCC 3.0 released: Switch from Kubuntu to Ubuntu

This week we have published version 3.0 of Univention Corporate Client (UCC) our desktop solution for the operation and administration of PCs, notebooks and thin clients. An essential change in comparison to previous releases is the change of the technical basis from Kubuntu to Ubuntu. Our reason for this switch was that Ubuntu offers longer support terms (5 years) for the Long Term Support (LTS) Versions. Kubuntu 16.04 LTS only offers support for 3 years. Customers thus profit from a longterm support for UCC. With this switch the desktop environment was also changed from KDE to Unity. Unity was especially developed for Ubuntu by Canonical. To achieve a better overview of all UCC images installed in one environment, all actually installed client images will be reported to Univention Corporate Server (UCS) from now on. As UCS is the central identity management system for UCC, these images will then be displayed for easy search in UCS.

UCS 4.1-3: Third Point Release published

The third point release of Univention Corporate Server 4.1 – UCS 4.1-3 – is now available to download. It includes various usability improvements, important security updates and all errata updates that have been published in the last three months. One of the main focuses of this release is on the further extension of the App Center such as offering software vendors the possibility to provide Docker-based apps.

Shortly Explained: Virtualization

Virtualization Schriftzug

In its simplest terms, virtualization is the replication of hardware resources via software implementations. It is employed in particular to provide multiple server systems on a single hardware system. Although I want to concentrate on the virtualization of server systems in this article, it is important to mention that these principles are also being applied ever more frequently in the fields of network technology and data storage as well as on clients too.

Univention App Center presented

In this video tutorial we give you a short introduction into the Univention App Center. The App Center is a central feature of Univention Corporate Server which allows you to easily install and manage additional UCS components and business applications of third-party vendors. You can thus adjust your IT infrastructure to your personal needs at any time. One crucial and great benefit of the App Center is the central management of all apps including their users via the UCS management system.

Cool Solutions – Guacamole…Not Just a Dip!

What are “Cool Solutions”?

Cool Solutions is the name we use to describe Univention solutions which expand UCS with practical, advantageous functions and are also sometimes employed by our customers. These solutions are regularly presented in the Univention Wiki in the form of Cool Solutions articles.

In a new series of articles, we want to introduce you to the five most popular “Cool Solutions” over the next few weeks. Today we are starting with Guacamole – and no, we don’t mean the tasty Mexican dip this time.
