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

UCC Univention Corporate Client Logo

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.

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.
