Distribution Release: Univention Corporate Server 4.4-2 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. The project's latest release is an update to the distribution's 4.4 series: 4.4-2. "We've just published the second point release for UCS 4.4. Apart from some bug fixes and corrections, we've also implemented some new features and, of course, we've put some work into numerous apps. Final Version of the UDM REST API: Looking back at the first point release (UCS 4.4-1 in June 2019), our REST API for the Univention Directory Manager was still in beta stadium. Good news: the interface for accessing the directory service is stable now. The API connects applications to the UCS directory service; access is granted via a web service using HTTPS, and data is exchanged JSON format. So, the REST API offers the same functionality as the udm command line tool. For example, it simplifies the maintenance of user properties or computer objects from connected systems. Developers of applications offered in the Univention App Center also benefit from the new, standardized access because they are no longer limited to the UDM Python interface."

Distribution Release: Univention Corporate Server 4.4-1 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. The project's latest version is an update to the distribution's 4.4 release, bringing with it performance improvements and application recommendations based on what administrators have installed previously. "The most obvious change is certainly the new app suggestion system in the Univention App Center. Based on the apps already installed in the UCS environment, administrators receive recommendations for suitable supplementary apps. These recommendations are based on the most common already existing combinations, e.g. the combined use of apps like Nextcloud or ownCloud with the Let's Encrypt application. Another improvement was the handling of interruptions during updates in the App Center. UCS 4.4-1 also brings a whole range of improvements to the area of Windows Services. Thus there are changes in the integration of Samba when dealing with server-side Windows profiles, in that the respective paths are now hidden in the file share, so that users no longer damage their profile unintentionally." Further details can be found in the project's release announcement and in the release notes. Download: UCS_4.4-1-amd64.iso (1,230MB, MD5, pkglist). |

Distribution Release: Univention Corporate Server 4.4-0 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. The project's latest release is Univention Corporate Server 4.4-0, which is based on Debian 9 "Stretch". "Univention is pleased to announce the availability of Univention Corporate Server (UCS) 4.4-0, the fourth minor release of UCS 4. It provides several feature improvements and extensions, new properties as well as various improvements and bug fixes. Here is an overview of the most important changes: With this release the new app Admin Diary is available, with which administrative events of all UCS instances of a domain can be viewed and evaluated centrally. Changes to users, groups or other objects in the directory service can be tracked just as easily as updates to servers or (de-)installations of apps. The Admin Diary is delivered as two components: a backend for data storage in an SQL database and a frontend for integration into the UMC. Recording of events is part of UCS 4.4 and is automatically activated when the backend is installed. The self-service app has been enhanced in two areas: End users can now use the self-service web interface not only for changing passwords, but also for editing their own contact information." Additional details can be found in the project's release announcement. Download: UCS_4.4-0-amd64.iso (1,229MB, MD5, pkglist). |

Distribution Release: Univention Corporate Server 4.3-3 |
|
Stefan Gohmann has announced the release of Univention Corporate Server (UCS) 4.3-3, the latest update of the project's Debian-based distribution for servers with a web-based administration system: "Third point release for Univention Corporate Server (UCS) 4.3 is now available. It includes a number of important updates and various new features. The portal is the starting point for many UCS users and administrators. As described in the blog article Design the UCS Portal with Drag & Drop, you can adapt it very easily to your needs. The 'Applications' and 'Administration' categories were static until now. We have extended the portal so that you can now define your own categories. In addition, you can add static links to the portal. In many environments different users should be shown different tiles. To do this, the group members for whom a particular tile is displayed are stored in the tiles. Previously, you could only assign each tile to one group. With UCS 4.3-3 you can now assign several groups to each tile. As soon as a user is a member of one of these groups, the corresponding tile will be displayed."

Univention Corporate Server (UCS) is a Debian-based server distribution that offers an integrated management system for central administration of servers, Microsoft Active Directory-compatible domain services, and functions for parallel operation of virtualised server and desktop operating systems. The Univention team has published a point release update for the distribution's 4.3 series, Univention Corporate Server 4.3-2. The new version contains mostly bug fixes and minor updates as listed in the distribution's release announcement: "During the upgrade to new UCS release- or patchlevel versions, the Univention Management Console is put into maintenance mode. While the maintenance mode is active, the progress of the update is displayed on a simple web page. Samba has been updated to version 4.7.8. For security reasons, authentication with NTLMv1 is no longer allowed. If there are still old systems or applications in use that absolutely need NTLMv1, this can be reactivated via the Univention Configuration Registry. The AD connector has been enhanced with tools to synchronize individual objects or entire subtrees again and to specifically remove rejects. Various security updates have been integrated into UCS 4.3-2, e.g. Apache 2, the Linux kernel and Samba 4." The release notes contain further details.

Distribution Release: Univention Corporate Server 4.2-2 |
|
Nico Gulden has announced the release of Univention Corporate Server (UCS) 4.2-2, a new build of the Debian-based server distribution featuring a web-based management system for central administration of servers. "We are pleased to announce the availability of UCS 4.2-2 for download, the second point release of Univention Corporate Server (UCS) 4.2. It includes all errata updates issued for UCS 4.2-1 and provides various improvements and bug fixes especially in the following areas: The portal is now also easily usable in cloud setups. The services installed on UCS, for example, are directly accessible without further configuration steps. For this purpose, the portal converts existing links into relative links. For portal entries with multiple links, heuristic procedures are used to determine the best link. The usability of the management system has been further improved. This allows users and groups to be copied, the error handling has been improved in several places, as did the performance." There have also been improvements to help app providers quickly create UCS appliances. Additional information can be found in the release announcement and in the release notes.
