External Storage (SMB) with LDAP User on iPad App / File Version Issue

help

#1

Steps to reproduce
1. Connect SMB/CIFS Share from Windows Server 2012 with Session credentials from ldap connection to Active Directory
2. On the iPad App Download a Complete Folder
3. When files are downloaded once and the folder gets gefreshed, the app shows that there is a new file version. But on the server the file hasn't changed.

Server configuration
Operating system: ubuntu 16.04.01 lts
Web server: apache2
Database: maria-db
PHP version: php7
ownCloud version (see ownCloud admin page): 8.2.7 and 9.1.0
Updated from an older ownCloud or fresh install: fresh install

Does anyone got the same problem? It is really annoying. I tried 2 different Versions of owncloud on ubuntu 16.04 and 15.10 und nextcloud on ubuntu 16.04 and everytime the same problem.
