Owncloud 9.1 MS Office Problem

Schritte zum Reproduzieren
1. Benutzer A öffnet z. B. eine Excel oder Word Datei über Webdav
2. Benutzer B öffnet die gleiche Datei, bekommt keine Meldung das diese bereits bearbeitet wird.

Erwartetes Verhalten
Benutzer B sollte einen Hinweis bekommen, das diese Datei bereits bearbeitet wird.

Aktuelles Verhalten
Die Datei kann unter Microsoft mehrfach geöffnet und auch gespeichert werden (es wird keine .tmp-Datei erzeugt).
Unter Libre-Office wird eine ~lock-Datei erzeugt. Beim Zugriff rein über LibreOffice wird die gewünschte Meldung angezeigt.

Hi,

locking einer Datei um zu verhindern dass mehrere Benutzer gleichzeitig an einer einzigen Datei arbeiten wird momentan gar nicht in ownCloud unterstützt. Das ist eine Sache des Clients (MS Office / LibreOffice).

Das hat nicht direkt mit Deinem Problem zu tun, aber verwende bitte immer die aktuellste Version (mometan 9.1.3) bevor Du hier Probleme meldest: https://owncloud.org/changelog/#latest9.1
