Univention Corporate Server (UCS)

UCS is a reliable, pre-configured Linux server operating system featuring: Active Directory-like domain services compatible with Microsoft Active Directory; a mature and easy-to-use Web-based management system for user, rights, and infrastructure management; a scalable underlying concept suited for single server scenarios as well as to run and manage thousands of clients and servers for thousands of users within one single UCS domain; an app center providing single-click installation and integration of many business applications from 3rd parties and Univention; management capabilities to manage Linux- and UNIX-based clients; and command line, scripting interfaces, and APIs for automatization and extension. Its purpose is to provide Microsoft Server-like services on the cloud or on the premises, to run and operate corporate IT environments with Windows- and Linux-based clients, and to extend those environments with proven enterprise software.

      Release Notes: This release fixed problems with the boot loader and added a new warning message when people want to select "base system" as the first UCS system role to say that no management system will then be available. The first system role has always to be the "domain controller master" which holds the initial copy of the directory service. The system roles were introduced to meet the different requirements of servers in larger environments.
