How to Deploy Meet Videoconferencing on UCS

Communication is at the core of any business. Lack thereof can create misunderstanding and friction. The fact that today’s modern workplace is no longer bound to a single physical location, has made communication between professionals more challenging though. Fortunately, technologies like email, chat and online video meetings are here to help us out.

The Univention App Center already offered apps for email and chat. And now, you can also make use of the great advantages of video communication thanks to Meet videocalling on UCS.

Secure Passwords for the UCS Domain

Obviously, your first name, cat’s name or mother-in-law’s birthday are not good passwords. Also password or 123456 (actually to be found on the list of the most frequently chosen passwords!) are out of the question. As the administrator of a UCS domain, you can’t prevent users from writing down their passwords or storing them under the keyboard, but you can tweak other settings to make the system more secure.
Policies can, for example, be used to specify a minimum length or to require users to change passwords regularly. In addition, Univention Corporate Server provides a quality check that forces the use of a certain number of numbers, special characters, uppercase and lowercase letters in passwords. This article presents some tips and tricks for setting up a good password policy in an UCS domain. We also show what variables can be set in the Univention Configuration Registry to optimize the whole thing. If you are using Samba in your environment, this article will also explain how to adjust the password requirements for the Samba domain object to those of the new policy.

Nursing and support agreement with the Max Planck Society including cost absorption

Bremen, November 27, 2019 – Due to the high interest of several Max Planck Institutes in using Univention Corporate Server (UCS) as a central identity management and platform for connecting various other services, a maintenance and support agreement between Univention and the Max Planck Society (MPG) was made last year.

The Way to the IT Concept For the Schools In the District of Harz

The district of Harz as a school authority recognized early, that a school has different needs than the public administration. Therefore the school IT is separated from the IT structure of the administrative district. Our structures enable us to remain flexible and to respond to the individual needs of the schools. A special school needs other applications and end devices than a grammar school. Nevertheless, both systems must be manageable and functional.

Web Proxy and “Shalla List” for Access Rules to External Websites and Higher Performance at the Same Time

For the IT administration of organizations with many users, typically also schools, it can be very useful to regulate the access to external websites. From a technical point of view, in order to improve performance when accessing frequently visited pages, but also in terms of restricting access to certain pages, e.g. for security reasons or to protect minors.
The web proxy, which is a central component of UCS@School, is used to improve performance and control data traffic. In this blog article I’ll show you how to configure Squid Proxy with SquidGuard and how to combine both with existing (youth protection) website filters. And with the “Shalla-List-Downloader” I would like to present you a Cool Solution, with which you can further round off this protection and which we have already successfully implemented in various school projects.
