The impulse for the development of UCS, which began in 2002, was the lack of a standardised Linux server operating system offering companies and organisations an alternative to Microsoft’s domain concept with the proprietary directory service Active Directory. Comparable Linux solutions (e.g., from SUSE and Red Hat) did not offer an integrated, cross-system user and computer management system, with the result that corresponding solutions had to be configured and maintained individually. Important early driving forces for the development of UCS were initially the Oldenburgische Landesbank and the department of the Bremen Senator for Education and Science, until the product was ready for market launch at the end of 2004. Since then, in addition to new versions, a number of software solutions based on the main product UCS have also been launched. UCS is predominantly employed in the German-speaking world by companies and public organisations from a wide range of sectors and fields, among others by the regional government authority of the federal state Brandenburg.
UCS is Open Source software; the proprietary developments of Univention GmbH included in UCS were published under the GNU GPL until Version 2.3. With the launch of Version 2.4, the company switched to GNU AGPL. There are also a range of software appliances based on UCS (e.g., in the groupware, desktop and IT service management fields).
Structure and components
Univention Corporate Server is based on the Linux distribution Debian GNU/Linux. There are numerous Open Source applications integrated in UCS, for example Samba, the authentication service Kerberos, the virtualization software Xen and KVM and Nagios for the monitoring of servers and services. However, the core and important unique selling point of UCS are the central administration tools "Univention Directory Manager" and "Univention Management Console", which allow the cross-system and cross-location management of IT infrastructures. UCS uses the directory service OpenLDAP to save data for identity and system management. The administration tools are operated via the web-based applications and command line interfaces. Thanks to the integrated administration service UCS Virtual Machine Manager (UVMM), the administration tools also allow the central administration of virtualized servers and clients, hard drives, CDROM and DVD images as well as the physical systems on which they are operated. The manufacturer goes to great lengths to guarantee possibilities for the integration of UCS in existing IT environments via the use of open standards and supplied connectors. In this way, the integrated Active Directory Connector allows the bidirectional synchronisation of the Microsoft directory service Active Directory and the directory service used in UCS, OpenLDAP. From UCS 3.1, UCS provides with "Univention App Center" an own graphic management component for the installation and deinstallation of third party appliances under UCS. Univention App Center in UCS 3.1 includes, beside Univention solutions, the Open Source groupware solutions Zarafa and Open-Xchange, the backup solution SEP sesam, the document management system agorum®core, the customer management solution SugarCRM and the dropbox alternative ownCloud.
