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. The REST API of the Univention Directory Manager is by default activated on all UCS 4.4-2 DC Master and DC Backup instances.

Aside from the significant improvements in Nextcloud 16, this version also delivers two much requested features: a secure LDAP connection and SAML SSO support. Both simply require the sysadmin to enable them, everything is pre-configured! Nextcloud is just the second app in the App Center supporting this easy SSO setup.
On the evening of September 6th, a vulnerability in the App Center repository server became known that allowed Docker images to be manipulated for Docker based apps. The vulnerability was in the Docker registry for the Univention App Center and allowed anonymous push of Docker images. The problem was fixed the following day by locking the anonymous push again.
Anyone who frequently participates in them knows that nothing is more disturbing than distorted scraps of conversation and lagging interlocutors. A flawless transmission, however, enables employees to focus on the essential topic and exchange information about it, even in a digital environment. It adds up to a good feeling keeping control of the data when discussing internal company information or when talking to customers.
PPD files (PostScript Printer Description) describe the technical capabilities of the printers. These files contain information about the printers’ features, i.e. whether it’s a color device, whether duplex printing is possible, which paper trays are available, which resolutions and which printer command languages are supported (e.g. PCL or PostScript). UCS provides a variety of PPD files, so most printers can be accessed and configured without having to install additional drivers. If you have to set up extra PPD files, please have a look at our manual.
We, the company bitpack.io from Birkenwerder, have modernized the IT infrastructure of the association in recent months. The new systems are running since July 2019: Univention Corporate Server is the central component; furthermore Kopano, Nextcloud and OnlyOffice are being used. In this article we would like to briefly introduce you to the project.
