User gets a security pop up every time he opens a file

After mapping a drive from a Windows 10 machine to the webdav share on owncloud, the user keeps getting a security pop up asking for username/password for every file they open.
Even ticking "Remember my details", the user is still getting asked for a password - once they enter the password, they can open that file. Then get another pop up when opening a new file.

Any ideas?

Steps to reproduce
1. Map a drive from within Windows
2. Open a file - the user gets a pop up asking for a username/password
3. This happens for every file the user opens even after ticking "Remember my details"

Expected behaviour
Once a drive is mapped with user credentials, the user should not keep on getting asked for a password

Actual behaviour
The user keeps getting asked for a password every time they open a new file

This is a behaviour on the Windows side, nothing ownCloud can influence. Using network connections instead of drive mapping this actually worked for me. Challenge continues in connection with MS Office ... again a MS issue. Recommend to open a ticket with Microsoft or use an external WebDAV Client. Cyberduck (open Source) or Mountainduck (paid).

Thanks Hodyroff,
Could you please clarify what you mean by "Using network connections instead of drive mapping"?


Its called "network location" in windows 10 it seems ...
(example if for FTP, just use the WebDAV adress from your ownCloud).
