How-To: Single Sign-On for Nextcloud

Log in once and automatically gain access to all programs and services – Single Sign-On (SSO) is a proven tool against the ever-increasing password fatigue among users. This is why many companies and educational institutions make it possible for users to log on centrally and only once.

How-To: Securing Networks with RADIUS

Many organizations and educational institutions allow users to work on their personal laptops, tablets and smartphones. Bringing Your Own Device (BYOD) is popular because it reduces the financial burden on businesses and gives users a greater freedom of choice as well as their familiar working environment. Before users connect to the school or corporate Wi-Fi with their personal devices, administrators should think about security so that the devices do not become a gateway for malware.

Secure in the Cloud – Two-Factor Authentication for Single Sign-On

Logo von privacyIDEA

Today many services are offered as web applications. This can be self-hosted systems such as ownCloud or Kopano or cloud services such as the Google G Suite / Google Apps for Work.

The number of services a user uses for his daily work is constantly increasing. So the desire for Single Sign-On is understandable. The user logs on centrally once and can then use all connected services without further authentication. The implementation of Single Sign-On was already described in more detail in the article Brief Introduction: SAML.

But in all cases, whether it is their ownCloud instance or Google G Suite, the user logs on to a web application that is available on the Internet. The login is accessible from everywhere – but also for everyone – and is therefore an interesting target for crackers, cyber criminals and industrial spies.

With the new version of the privacyIDEA SAML App companies can decisively increase the security of the Single Sign-On process.

In addition, you can add static links to the portal, e.g. also link an imprint here.

Multi Container Support for Docker Apps for Univention App Center

Container technology Docker Logo

Since the release of UCS 4.1 in November 2015, the App Center has supported Docker apps. These are applications in the form of Docker images that are deployed by the App Center in a Docker container. To do this, the App Center downloads the Docker image of an app and starts the Docker container. We call these apps “Single Container Apps” because the App Center only supports one container per app. This functionality is sufficient for many apps.

Until now!
