Domain Replication Service (DRS) with Samba for Empowering Distributed Environments

In larger environments with thousands of users, you can often find multiple Domain Controller offering authentication and authorization services. For Windows-based endpoints, UCS utilizes Samba 4 to provide these services. In between the different Samba 4 servers, UCS uses the Domain Replication Service (DRS) to keep the server data synchronized. While Samba 4 does a superb job in replicating the data, there are some tweaks you can utilize to optimize the replication, to provide better performance in distributed environments. Let us have a look!

UCS 4.4-4: Fourth Point Release of UCS 4.4

We’ve just published the 4th point release of UCS 4.4: apart from bug fixes and some patches, we added some cool new features and improved numerous apps. For example, UCS 4.4-4 introduces logging of LDAP authentications, something that was previously only available via Samba 4.

Provide Solutions for Home Office Team Collaboration

In recent days and weeks, many employees retreated to home office to break chains of infection, others plan or would like to do so. But not everyone has the tools to continue working productively and together with colleagues in as many areas as possible. Working remotely and the collaboration of several people from the home office place special demands on the way a team works and on the tools it uses.
As an open hyperintegration platform and with the Univention App Center, Univention Corporate Server (UCS) offers a whole range of different applications which enable effective and collaborative working from the home office. Among the more than 90 applications in the App Center are solutions for file sharing (Nextcloud, ownCloud or Seafile), for project management (OpenProject and the Kanban solution Wekan), video conference (Kopano Meet), real-time communication (Rocket.Chat) or knowledge transfer (MediaWiki Bluespice). All these solutions are also available as virtual appliances with a pre-configured UCS, which you can put into operation with a very manageable effort and make available to your colleagues for the home office.

UCS@school 4.4 v4 brings improved exam mode, computer room control and ID connector

The UCS@school team released the 4th version of the UCS@school app a few weeks ago. It is technically based on UCS 4.4 and brings some new functions as well as various adjustments and improvements.

In this article, I would like to give you a short overview about the most important new features for administrators and users, especially in the exam mode, computer room and laptop class control, single sign-on and printer control. Very interesting is the new ID-Connector, which enables data transfer between federal state directories, school district directories and school directories.

Separation of Users in Office 365 Through Synchronization of Several Azure Active Directories

Identities and roles in a Microsoft Azure AD environment can be provisioned very easily thanks to the Office 365 Connector App for UCS. Users can get an easy single sign-on access to Office 365 resources while maintaining control over the information conveyed about each identity.

Moreover, in a UCS environment, precise permissions are often defined to control the visibility of user properties within an organization. Especially in large environments it is necessary that not every user “sees” every other user. For example, the data protection requirements at schools are implemented by UCS@school: The school authorities can administer user accounts centrally across all schools, but users only “see” each other within their own school. In a single Azure AD, such a separation is generally not provided, but the creation of several Azure AD or tenants is expected.

In this article I am going to explain how you can implement such separate setups with UCS for Azure AD more easily and how the scenarios are structured since the last update of the Office 365 Connector App.

How to integrate with LDAP – Example Redmine

In the blog article series “How to integrate with LDAP”, we introduce a whole range of different options and possibilities for how you can use LDAP provided by UCS to expand or use in cooperation with other services.

In the first section of this article, “Typical Configuration Options”, I will be using an example to demonstrate the sort of information typically required to perform user authentication against the UCS LDAP. I will be taking you through the necessary configuration steps using the project management system Redmine as an example, as this requests all the typical information.

In the second section, “Types of Search Users”, I will detail the possibilities available to you if it is not possible to search through the UCS LDAP anonymously.
