Release
UCS 5.2
2024
Univention
Summit 2024
There is no UCS 5.1?
Not officially: „UCS 5.1“ is an internal technical release to „skip“ one debian release
More in the announcement: https://www.univention.com/blog-en/2023/06/announcement-ucs-release-5-2/
Debian 10 Debian 11 Debian 12
Focus of UCS 5.2
» Maintenance & updated software version
» Debian and other upstream updates:
Kernel, Samba, OpenLDAP 2.5, Python 3.9, Docker 20.10, PostgreSQL 15, ...
» Move to Keycloak instead of SimpleSAMLphp/Kopano Connect
» No more Python 2 support
» Features are build in Apps, and will be available also for UCS 5.0
» Strategy: Move features into Apps allows other release variants like for Kubernetes – more later
today
New features in Apps, not UCS releases – what does that mean?
» Let me show you some examples….
What has happened in 2023 – Release policy
» Quarterly patch level releases
» Released: 5.0-1 to current 5.0-6
» 5.0-7 to be expected in March 2024
» Longer maintenance periods for patch level releases
» At least 12 weeks after the next release
» Example: 5.0-6 will be maintained 12 weeks after the release of 5.0-7
more details: https://www.univention.com/blog-en/2023/07/ucs-patchlevel-releases-adjustments/
What has happened in 2023 - Documentation
» Reworked entry and documentation navigation
» Integrated extensive search across all documents
» New content:
» UCS architecture manual
» App specific manuals: Keycloak,
OX Connector, Guardian, Intercom Service
» Manual to onboard Debian an Ubuntu
administrators
» Maintenance life cycles of Univention products
What has happened in 2023 - Keycloak
Image source: https://www.keycloak.org/
What has happened in 2023 – Active Directory Connector
» Active Directory Connector synchronizes
directory structures, users and groups between
UCS and Microsoft Active Directory
» Including password hashes
» New in 2023 „AD Forest“ support
» Active Directory Connector synchronizes one
AD Domain of a Forest structure
» References to objects in other Domains of
the Forest are handeled correctly
What has happened in 2023 – OX Connector
» OX Connector was introduced in 2022 to connect Open-
Xchange installations
» Univention App „OX App Suite“ had different
integrations with different features
» Since May 2023, both are based on the OX Connector
» Customers can choose: Deploy OX App Suite on their own or
use the Univention App
» New „reference“ for integrations:
» Integration („Connector“) and Service in two installation
packages („Apps“)
More in
https://www.univention.com/blog-en/2023/05/unification-administration-provisioning-ox/
What has happened in 2023 – Roles & Rights
» Roles & Rights:
» Project to allow easy definition
of rights in the Univention Tools
» Open Authorization Framework which
can be used in other Services
» Announced Summit 2023
» In 2023:
» First implementations in a customer project done
» Released „Guardian“, the new authorization API, to UCS
» Work is ongoing to release a generic user management UI for UCS@school
» More in https://www.univention.com/blog-en/2023/08/role-design-ucs-ucsschool/
Ongoing implementations – block previously used values
» Objective:
» „block“ re-usage of former used usernames or mail addresses
» to avoid account takeover („impersonation“)
» Will introduce a configurable „blocklist“
» stores values once a user (or other objects) are deleted
» will be checked by UDM for conflicts
» attributes and durations will be configurable
» Planned for Q1/24
Back to UCS 5.2 – where are we?
» First Alpha release in 12/2023
» https://www.univention.com/blog-en/2023/11/ucs-alpha-5-2/
» Status:
» All Debian packages imported, all Univention packages build
» Package upgrade UCS 5.0 UCS 5.1 UCS 5.2 in one migration window
→ →
» Basic functionality of UDM, UMC, Portal
» Objective of the Alpha release:
» development environment for Univention & App providers
Back to UCS 5.2 – what happens next?
» Pending tasks:
» Finalize installation procedure with Keycloak as default
» Improve look & feel of the UIs
» Provide further Univention Apps
» Testing, testing, testing, ...
» Beta release(s) to be expected in Q1/Q2 2024
» Stable release in 2024
» No commited date yet – we allow to give features / customer needs priority
» UCS@school for UCS 5.2 will be released immediately or short after
Be prepared for UCS 5.2
» Migration to Keycloak is a prerequisite
» UCS 5.2 has no other IDP, a migration in UCS 5.0 is needed beforehand
» Migration guide is available: https://docs.software-univention.de/keycloak-migration/index.html
» For „old“ UCS installations: migrate OpenLDAP backend from BDB to MDB
» https://help.univention.com/t/migration-of-openldap-database-backend-from-bdb-to-mdb/22322
» Ensure no customization uses Python 2 anymore!
» Univention Apps & Integrations are or will be migrated
» Keep UCS 5.0 up to date
» All instances in a domain need to run on a maintained 5.0-x release before upgrading the UCS Primary
Node to UCS 5.2
» Enjoy the features coming to UCS 5.0 
VIELEN DANK!
