Minimal Configuration 
Depending on the users of your system, you may want to restrict functions as well as access permissions.
By default, the CM repository documents is delivered for storing documents and metadata. For a minimal configuration, you deactivate the repository services that you do not need (for example, the discussion service for creating discussions) in the configuration of this repository manager. If you integrate your own repositories, you should also reduce the number of repository services to a minimum. However, you should not change the configuration of repository managers that are used system-internally.

The KM flexible user interface provides you with interface commands for carrying out operations. For a minimal configuration, you should deactivate interface commands that cause changes, including commands for checking objects in (Upload, Create New Text File. Create New HTML File), commands for editing objects (Edit Locally, Edit Online) and commands for deleting objects.

Permissions dictate whether a command can be carried out. A user without write permission can not use the commands for creating a new file. Deactivation is therefore only necessary for a minimal configuration or for performance reasons.
