The third point release of UCS 4.2, UCS 4.2-3, is now available. It includes all errata updates issued for UCS 4.2-2 and provides various improvements and bugfixes especially in the following areas:

  • For the UMC diagnostic module, a large number of additional functional tests have been added to help the administrator check the health of the server and the entire domain.
  • The usability and configurability of the management system were further expanded. The design of the assistants and dialogues of the management system was revised with regard to usability aspects. Additional configuration options for the single sign-on of the management system have also been added, e. g. the configurability of the certificate used.
  • When a UCS system joins a Microsoft Active Directory domain, more checks are now performed. This allows to display information about known problems, including hints on how to correct them.
  • Various security updates have been integrated into UCS 4.2-3, for example for the Linux kernel, Samba, Asterisk.

A detailed list about the changes can be found in the changelog in the Release Notes. Questions can be asked in the Univention Forum, section UCS.

`The second point release of UCS 4.2 is available.

A special highlight concerns the management of services and Apps that are operated in public cloud services such as the Amazon Marketplace. Services installed on UCS can now be accessed directly without any further configuration effort.

Other innovations include:

  • An overall improved look & feel of the Univention Management Console.

  • Simplified administration, e.g., through easy duplication of users and groups, and optimized error and alert messages.

  • Automated creation of virtual appliances for App vendors.

  • An Appliance can be equipped with the vendor's individual
    corporate design.

  • Software updates for OpenLDAP, Samba, MySQL, PostgreSQL.

  • Updated Linux kernel to version 4.9.33 for higher security and stability.

  • New feature "App Setttings" for the configuration of Apps via text forms.
