Reporting for professionals: Log activities in the UCS LDAP directory service

Many services and processes running in a domain document their activities fully automatically in the background. The log files contain information about users’ logins to the system, installation and uninstallation of software, access to web pages, error messages and other information. Univention Corporate Server (UCS) also creates such reports – either behind the scenes in the form of log files or by using the UCS Admin Diary. You can also obtain ready-made reports as CSV or PDF files via the Univention Management Console or Shell.

In this article, I would like to show you how to create audit-proof log files of the LDAP directory service with Univention Directory Logger. I’d also like to tell you how to obtain a complete overview of the operations in a UCS domain with Admin Diary and how you can evaluate data from the directory service with Univention Directory Reports.

Connecting Ubuntu and Linux Mint Clients to UCS Domains: New Version of the Univention Domain Join Assistant

The Domain Join Assistant for Univention Corporate Server (UCS) automatically integrates Ubuntu and many Ubuntu-based systems such as Linux Mint into a UCS domain.

The tool offers a graphical user interface and a command line tool for admins who prefer to work on the shell. We have just released a new version of the Domain Join Assistant that comes with various improvements and supports the latest Ubuntu and Linux Mint versions. In this article I’m going to show you how the tool works and I’m going to introduce the new features.

Release UCS 4.4-5 brings improvements in Single Sign-on, Self Service, more performance for LDAP and compatibility with Python 3

The release of version 4.4-5 of Univention Corporate Server (UCS) brings a series of technical innovations for the Single Sign-on of users to applications connected to UCS. There are also new functions for the UCS Self Service. Users can now register themselves at a UCS domain via the User Self Service and create a user account, assign a user name and password, and store further information. Performance improvements in the LDAP directory service have accelerated the replication of groups. And in preparation for UCS 5.0, which is scheduled for release at the end of this year, our development department has made more than 45 UCS packages compatible with Python 3. So when you upgrade to UCS 5.0, the corresponding code parts in UCS will run for both Python 2 and Python 3. In addition, we have also published a preview of the new UCS 5 portal as an app in the App Center for testers. It already brings important new technical features such as embedding apps directly into the portal page.
