- Univention Configuration Registry variable#
- UCR variable#
A Univention Configuration Registry (UCR) variable is a named setting that stores system configuration in a central registry. Instead of editing configuration files directly, you use UCR variables to manage local system configuration. When you change a UCR variable, the system automatically regenerates all configuration files that depend on it.
For more information about UCR variables, see Administration of local system configuration with Univention Configuration Registry in the Univention Configuration Registry section.
- Univention Directory Manager#
- UDM#
Univention Directory Manager (UDM) is the abstraction layer between the domain database and the administrator. It’s responsible for domain management in Nubus for UCS, covering identities, devices, and services across the domain.
UDM provides data aggregation, data consistency, input validation, and process logic on top of the LDAP directory. Administrators can use UDM through the web interface in the Management UI, the command line (univention-directory-manager or udm), or the HTTP REST API.
For more information, see Domain management in Univention Corporate Server 5.2 Architecture [1].
