Release UCS 4.3: Easy administration of portal pages, higher performance and single sign-on for apps

With UCS 4.3 we have integrated numerous security updates – most recently the Samba 4 update of March 13 – and closed hundreds of bugs. But not only, we also focused, among other things, on a significantly higher performance during data import and more convenience in the administration of portal pages or users, for example. In addition to an efficient and easy management of UCS, it was also important to us to create a positive user experience with UCS. Here, worth mentioning milestones are certainly a single sign-on during login to Windows or Linux desktops, which in parallel allows access to the Univention Management Console, Office 365, and ownCloud or Nextcloud, just to name a few of the improvements.

With UCS 4.3 we took another resolute step in the development of UCS into an open platform for IT operations and management in enterprises – whether it is a small organization with just a few users or organizations with hundreds of thousands of users.

Critical Security Update for Samba Published

The Samba team discovered a critical vulnerablity in the access control of Samba/AD domain controllers. Any authenticated user can change other users’ passwords over LDAP including the passwords of the administrators.

We strongly advise to install the updated Samba packages for all UCS versions currently supported (from UCS 4.1-5 and UCS 4.2-3) which we have distributed today via the usual errata update channels.

Administration of Tablets in Everyday School Life with Mobile Device Management (MDM)

With the increased interest of schools to use tablets in classrooms, the Kreismedienzentrum Wildeshausen (media center of the district Wildeshausen) experienced a significant increase in inquiries for circulating tablets in 2015. In order to guarantee a safe operation of the equipment regardless of the location, the institution was faced with the task of organizing a reliable central tablet management.

Due to lack in personnel at the KMZA it was impossible to organize a manual device management, in which the tablets are connected to a laptop via USB cable and the subsequent MDM configuration is carried out individually.

In addition to the central tablet management, they planned to lend the devices to the schools as a so-called ‘suitcase solution’ and wanted to make remote maintenance possible.

Brief Introduction: How Can UCS Systems Be Updated Automatically?

Like any operating system manufacturer, Univention usually publishes weekly updates. As an administrator, you want to install them as soon as possible. However, in large UCS environments with many connected servers, manual updates can take a lot of time, which is not always available every week. The easiest way to reduce such a big workload is to automate the task by using policies.

In the following, I want to explain how you can set up an automated update of UCS systems by using the policy ‘maintenance settings‘.
