First point release of UCS 4.2 published

With UCS 4.2-1 the first point release for Univention Corporate Server 4.2 is now available.

It includes various detail improvements and error corrections. Some of the most important changes are:

  • The forwarding of e-mails per each mail user can now be saved in the UCS management system.
  • Improvements in changing the password in the Univention Management Console: From now on, also users from a Microsoft Active Directory domain can change their expired passwords. In addition, more hints are now displayed if the password change should fail.
  • The possibilities for IPv6 (Internet Protocol Version 6) configuration have been improved in various services, for example in the Nagios or proxy server configuration and in the UCS management system.

Data Privacy-Compliant Integration of Office 365 in Fulda schools

The municipal authorities of the German city of Fulda in the state of Hesse are responsible for the administration and operation of the IT in 23 schools in Fulda – including 2 vocational schools and 2 grammar schools – for a total of 13,000 pupils and 1,000 members of teaching staff.

Unlike in the rest of Hesse, as an education authority for a small city, we have the city’s own well-developed fiber-optic network at our disposal. The majority of the schools are already connected to the fiber-optic network covering the whole city, which allowed us to do away with local servers in the schools at an early stage and focus on a centralized IT concept instead. As a result, all the school IT in Fulda now runs over centralized servers in our administration center. We operate an Active Directory domain of our own design on these servers with centralized domain controllers, to which a terminal server farm comprising both Windows and Citrix servers as well as the central file servers are connected.

Facilitate Your Work by Integrating Listener Modules in UCS

Graphic Listen to me!

Listener modules support you in your administrative work by synchronizing and controlling all changes in the UCS’ OpenLDAP Einacross all connected services – Learn how to build and use them!

You are surely using a variety of (cloud) services in your organization and, if required, these services will make changes to your directory service, either Active Directory or OpenLDAP. In heterogeneous environments, where UCS is typically used, the question is, how can service A notice the changes that service B has made to certain objects in the directory, and that are relevant to both services? For example, when a new printer has been added to the network, and has joined the UCS domain, the list of printers is updated in the configuration file of the printer service (CUPS) and the service reloaded.

We Published Samba Security Update

Our development has released a Samba security update that closes a security gap that allowed attackers to make the Samba (smbd) fileserver component execute program code from a library that the attacker themselves copied to a writable file share. This so-called remote code execution (RCE) could be used to extend the privileges of the attacker, right up to the takeover of root privileges on the server.

The groupware solution OX App Suite, available in the Univention App Center, is aimed at companies, educational institutions and public administrations looking for a modern and future-proof communication solution.

OX App Suite is a modular communication and collaboration platform. It is based on open standards and can be used in combination with Univention Corporate Server (UCS) for the integration into existing IT infrastructures.

Brief Introduction: Two-Factor Authentication

Fingerprint authentication
As part of our “Brief introduction” series, you will learn today what is meant by two-factor authentication.

If you are planning to use security software, you will surely stumble upon this term, as this method provides additional protection for your business when it comes to login processes, especially for data-sensitive areas. Often enough, it has happened in the past that the identities and associated passwords of users from, for example, large mail providers like Yahoo were stolen. As users often use the same password for different services, there is a risk that the criminals use the stolen data to gain access to other services, thus causing great damage. Securing user authentication against sensitive areas or business-used services not only by requesting a password but also through a second authentication, data breaches become much more difficult for attackers.

Brief Introduction: Samba / Microsoft Active Directory

Get a brief understanding about the software Samba and Microsoft Active Directory – two solutions for the central detection and authorization of domain members. These are important features as the central administration of a domain network helps to achieve more data protection and higher failure security for your IT systems.

Learn also more about how UCS is able to bridge the gap between the Linux world and the Windows world so that you can reap the benefits of both systems.
