MDM Server Application Properties

This article is intended to serve as a reference point for MDM server configuration. As such, it provides an overview of the available properties and, when applicable, refers users to more comprehensive sources. The properties described here are defined in the mdm-server/etc/application.properties file. For each property, you will find information about the required data type, its default value, and a short description. The Mandatory column specifies whether a property is required for the application to run and function as expected.
