NEW • Development Release: Univention Corporate Server 5.0-0 Beta |
Rate this project
|
Univention Corporate Server is an enterprise-class distribution based on Debian GNU/Linux. It features an integrated management system for central administration of servers and Microsoft Active Directory-compatible domain services. The project's latest snapshot, Univention Corporate Server 5.0-0 Beta, introduces a number of changes to the user interface. "The most obvious change is the modernized design of UCS 5, which can already be seen during the installation process. In the default configuration, UCS will appear darker and, in our opinion, more elegant and uncluttered. We have visually reduced many areas and defined simpler shapes with a clearer color language, for example, for the "tiles" in the portal. As the changes in the beta are very obvious, the status of an "unfinished" beta version becomes clearly visible, in particular in this area. A lot of work is currently being done on the look and feel of UCS 5. In many places, the interfaces are still incomplete or partly still use visualizations from UCS 4." Additional information is available in the distribution's release announcement. Download: ucs_5.0-0-beta-amd64.iso (888MB, MD5, pkglist). |

Development Release: Univention Corporate Server 5.2-0 Alpha |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. The distribution is transitioning to a new base, using Debian 12 as its foundation, and Unvention has published a new alpha snapshot to test the new technologies. "UCS 5.2 will be based on the latest stable Debian version: Debian 12 “Bookworm”. This includes new versions of PostgreSQL and MariaDB, Docker and OpenLDAP, among others. The Alpha version has already completed this step, all packages from Debian have been adopted and partially rebuilt with our enhancements. Especially for application providers it is worth to have a look already today. Early testing ensures that the app will be available in the App Center on the day UCS 5.2 is released. UCS 5.2 now also comes with Keycloak as our single sign-on solution. We have already described the long road to this here. Keycloak is already functional in the Alpha version and will be even more integrated in the final version." Additional information is provided in the release announcement.

Distribution Release: Univention Corporate Server 5.0-5 |
|
Univention Corporate Server is an enterprise-class distribution based on Debian GNU/Linux. The distribution has received a minor update, Univention Corporate Server (UCS) 5.0-5 which introduces new functionality to the management console along with a number of bug fixes. "Univention Corporate Server 5.0-5 is the fifth point release for Univention Corporate Server (UCS) 5.0. It contains all erratas released since version 5.0-4 for bug fixes, performance improvements and security updates for Samba, Linux, OpenSSH, Bind and Python, among others. UCS 5.0-5 is available in the 'Software Update' module and can be found in our download area. In total, the new point release includes 28 security updates that we have provided since the last UCS point release, such as those for Samba, Linux, OpenSSH, Bind, and Python. We have also implemented various bug fixes in the Univention Management Console (UMC) environment and upgraded some UMC modules to the new capabilities that have been available with the UMC server since the fundamental change from UCS 5.0-4. In the future, we will be able to significantly reduce the memory consumption of UMC during operation in certain cases. Also worth mentioning is the new option of explicitly setting an empty value or deleting the value in the UMC module for the Univention Config Registry (UCR)."

Distribution Release: Univention Corporate Server 5.0-4 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. It features an integrated management system for central administration of servers. The project has published a new update to its 5.0 series which streamlines the Management Console Server and Web Server programs. There have also been a number of Samba updates with a focus on improved performance. "Univention Management Console Server and Web Server are now merged into a single program and the implementation uses Tornado instead of the UCS specific Python Notifier. The integration of Keycloak has been improved for operation with accessibility from the Internet, for outgoing passwords and for the migration of existing SimpleSAMLPHP based connections. We will inform you about details of the upcoming Keycloak developments in a separate blog article. At radius it is now possible to add the user name mailPrimaryAddress to register, which guarantees more flexibility when registering. Samba has been updated to version 4.18.3. The latest version of Samba contains numerous optimizations that lead to improved performance. Upstream maintenance is also ensured by using the latest Samba version." Details can be found in the release announcement and in the release notes. Download: UCS_5.0-4-amd64.iso (1,012MB, SHA512, signature, pkglist). |

Distribution Release: Univention Corporate Server 5.0-3 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian. The distribution's 5.0 series has been updated, bringing new features, improved performance, and some new security options. "Determine group membership of users faster: The group membership of a user in UCS is now conveyed via the 'memberof' attribute of the user. This means you no longer have to search across all groups for a user but can access a cache on the user object that contains this information. This considerably speeds up the search for group membership. Synchronisation of password history: With the new UCS version, to prevent the use of passwords that have already been used, a user's passwords that have been used in the past are stored in a history. For this purpose, UCS saves hashes of the passwords in the history. In the past, the history was saved individually by the system that processes the password change - this can be OpenLDAP (for changes via UDM and Kerberos), Samba4 (for changes via desktop systems in the UCS domain) or Active Directory (when using the AD connector)." Additional information can be found in the release announcement and in the release notes. Download: UCS_5.0-3-amd64.iso (923MB, SHA512, signature, pkglist). |

Distribution Release: Univention Corporate Server 5.0-2 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. It features an integrated management system for central administration of servers. The distribution's latest update includes improved virtual local area network (VLAN) management: With version 5.0-2, RADIUS now also allows administrators to assign dedicated VLANs to specific user groups. For example, visitors can be assigned access to a dedicated guest VLAN that allows access only to the Internet, but not to the organization's internal network. This is an important feature for increasing network security. For more info, see the blog article Service-specific Password for RADIUS. Minor enhancements and bug fixes have been released for the App Center, which in detail can be found in the release notes. Here, we have focused on porting more apps to UCS 5 as well as the deployment of new apps." Additional information can be found in the distribution's release announcement and in the release notes.

Distribution Release: Univention Corporate Server 5.0-1 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. It features an integrated management system for central administration of servers. The project's latest release is an update to the 5.x series which improves user account management. "Administrators can specify an activation date when creating a new user account. User accounts with an activation date in the future are deactivated after creation and are only activated on this date. Thus, user accounts can be created in advance and UCS automatically takes care of the staggered activation. For the creation of users, there is a wizard in UCS that asks for all the required information. Administrators can specify additional attributes as required for a user account in addition to those already required, such as last name, user name, and password, for example, the e-mail address. As soon as additional attributes are defined, they are now also displayed in the UCS 5.0-1 wizard when users are created. This guarantees that administrators can also assign customized values for these attributes and not only the default values are used." Additional details can be found in the distribution's release announcement. Download: UCS_5.0-1-amd64.iso (913MB, SHA512, signature, pkglist). |

Distribution Release: Univention Corporate Server 5.0-0 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. It features an integrated management system for central administration of servers. The distribution's latest release is Univention Corporate Server 5.0-0 which is based on Debian 10 and uses a new dark theme for the web interface. "The fifth major release of Univention Corporate Server is ready and available for download. UCS 5.0 contains new features, has a fresh look, comes with several improvements and bug fixes. The new version also uses a new core: UCS 5.0 is based on Debian 10 (Buster) and Python 3. In this blog post, I would like to introduce the most important changes, give tips for the upgrade process and reveal what we’re planning for future releases. Univention Corporate Server features a new dark look, also visible during the installation, which gives the distribution a modern and elegant, yet tidy touch. The clean look is also present in the web interface: many areas have been visually reduced. The tiles in the portal, for example, now appear in a new colour theme."

Distribution Release: Univention Corporate Server 4.4-8 |
|
Univention Corporate Server is an enterprise-class distribution based on Debian. It features an integrated management system for central administration of servers. The distribution's latest release is Univention Corporate Server 4.4-8 which improves the performance of the distribution's web-based services and paves the way for a smooth upgrade from the 4.4 series to 5.0. "The performance of the UMC web server in large environments where there are many requests has improved. For this purpose, the UMC web server has changed from single to multi-processing. Thus, it can no longer run in one process only, but in several processes, to actively use several CPU cores, at the same time. The number of processes used is configurable and should not exceed the available CPU cores. In particular, large UCS environments with many login requests in a short period benefit from this change. Advanced Parameterization of Docker-based Apps. App developers from the Univention App Center can now store the call command for their Docker-based apps as a UCR template. Therefore, they can enable further parameters for their app." Additional information can be found in the company's release announcement. Download: UCS_4.4-8-amd64.iso (1,300MB, MD5, pkglist). |

Development Release: Univention Corporate Server 5.0-0 RC 0 |
|
Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. The distribution's latest development snapshot improves the application centre and polishes the Univention Management Console. "Since the beta release, we have significantly expanded the App Center. During the implementation of the largely redesigned user interface of UCS 5, we have significantly improved its clarity and simplified access to functions even more. We were able to clearly improve the App Center’s handling of dependencies between individual apps: If an app requires the installation of another app in advance, the installation of all required apps will now be executed in one go. Take the Admin Diary Frontend as an example. It requires the installation of the backend component for data storage. Up to now, dependencies were recognized and requested, but the installation of the individual apps had to be done separately, one after the other. A completely new feature is to select several apps in the frontend and to install, update or uninstall them in one step. For this purpose, all required app information and setup questions are collected by the App Center which then carries out the (un-)installation or the necessary updates in a single step. This facilitates the commissioning and updating of UCS environments significantly." Additional information can be found in the project's release announcement.
