If you need to use various services online, which is by the way the norm, there’s nothing more conventient than using single sign-on (SSO). SSO allows you to log in to all available services in a domain with one password only. UCS provides this feature via the SAML Identity Provider since UCS 4.1. We chose to […]

The cumulative outages of the Amazon Web Services and the attacks on the global DNS network have shown that even large and supposedly professionally protected networks are endangered, too. These incidents also make us aware of the need to distribute critical infrastructures across multiple cloud providers. This distribution is particularly important for centralized authentication services, […]

The professional structure of domains and the use of domain controllers bring order to IT infrastructures. This is especially important when organizations are growing rapidly. Professional domain management allows their IT to grow dynamically. Otherwise, the infrastructure becomes a kind of “patchwork carpet” of many small solutions and unorganized resources, some of which act independently […]

More than two years after the start of one of the largest projects in which Univention has been involved to date, a new mail platform with over 30 million managed end users finally went online in late 2016. UCS takes care of the identity management duties for all the user accounts. I first reported on […]

Last year I submitted my Master’s thesis titled “Secure Operation of Existing Applications in the Corporate Environment with Open Source Tools”, and successfully earned my degree in IT from Bremen University of Applied Sciences. My research focused in particular on the differences and the security-related advantages/disadvantages of server virtualization compared with operating system virtualization, which […]

As a long-term Univention partner, we at Adfinis Sygroup operate UCS environments for many of our customers. We employ Ansible for automation when running different Linux distributions as it standardizes the roll-out of UCS among other things. Up until now there weren’t any Ansible modules available for UCS-specific tasks. To remedy this, we developed modules […]
