The latest patch-level release of Univention Corporate Server bundles all new features and improvements from the past three months onto new installation media. UCS 5.2-6 brings highlights from Univention Nubus such as a new metrics endpoint for improved observability and technical details for directory objects in the Management UI and additions to the mail stack with alternative mail addresses for groups. When analyzing configuration issues or end-user incidents, it is often necessary to access technical information used in the backends, such as the Univention Object Identifier. To simplify the process of matching real names with technical identifiers for users, groups, and any other information stored in the directory service, the Management UI now includes a new section with these identifiers. This is helpful in several scenarios: if a warning or error containing a technical identifier is logged in a backend service, administrators can now search for that identifier directly in the Management UI and easily access the full information about the affected object.
