In the user profile the user can upload his avatar / portrait image. When the system is attached to an external management system that creates users via REST API and also uploads the user image via REST, it might not make sense to allow users to change their image within OpenOlat.
A new config option in olat.properties is implemented to disable the user upload of the portrait image
In the ProfileFormController the portraitUpload is set to disabled when managed.
