Univention Corporate Server 5.0-6

The sixth patch level release for Univention Corporate Server (UCS) 5.0 is
available with Univention Corporate Server 5.0-6. It contains all bug fixes
and security updates released since version 5.0-5, including for PostgreSQL,
Samba and a number of Univention's own packages. Also included are various
preparations for the upcoming UCS 5.2.

UCS 5.0-6 is available in the "Software Update" module and can be downloaded
from our download area.

Increased Stability and Security

In the last three months we have released 47 security updates, most of them
from the Debian base distribution. However, we have also fixed security-
relevant errors in the Univention packages, e.g. password leaks via the
process list. We have also further stabilized the Univention Management
Console (UMC) when connecting to the individual UMC modules. We have
improved the way the Univention Directory Manager (UDM) handles inconsistent
user capitalization. Some data is now updated atomically by the portal, which
avoids certain error patterns, and the self service now translates the forms
correctly in all cases.

There have also been some improvements: UDM's REST API now evaluates certain
request headers when deleting objects and returns more useful responses in
case of errors. A new feature is the ability to synchronize subdomains of an
Active Directory Forest (AD Forest) with the Univention AD Connector.

Preparations for the Upcoming Minor Release UCS 5.2

We have been working hard on the next minor release of UCS for the past few
months. A few days ago we released the first pre-release: UCS 5.2 Alpha. At
the same time, we have already integrated some changes into UCS 5.0-6, which
will make an update possible as soon as the final version of UCS 5.2 is
available. For example, the SimpleSAMLphp packages have been prepared for
removal and a script has been added to check the migration status from
SimpleSAMLphp to Keycloak as identity provider. In addition, the logic in our
LDAP replication has been adapted to support the new schema from OpenLDAP 2.5.
The UMC Updater module will no longer show UCS 5.1 as a possible option, as
UCS 5.1 is an "intermediate version" and you should be able to update directly
to UCS 5.2.

Patch Level Releases Every Three Months

You can install UCS 5.0-6 now, although we will continue to provide security
updates for UCS 5.0-5 for another 12 weeks. However, administrators of UCS
5.0-4 should update now at the latest, as we have discontinued maintenance for
this release.

The next patch level release - UCS 5.0-7 – will be released in early to mid
March 2024. This release will also focus on security updates and stability.

More information can also be found in our release
notes and in our
help article on installation.
