Created attachment 156317 [details] Screenshot of HTTP error SUMMARY I currently access my workplace's Sharepoint drive in Dolphin via webdav. In order to make this work, I first had to authenticate using konqueror so that the necessary token is stored as a cookie. After this, dolphin will happily navigate to Sharepoint's webdav frontend. It mostly works great and I can perform normal file operations (moving, renaming etc.) as well as opening files. The problem comes when I try to open a file using LibreOffice. Dolphin *thinks* that LibreOffice can open http/webdav URLs directly, because it sets the X-KDE-Protocols property in its .desktop files. The problem is that LibreOffice isn't able to access the file because it doesn't have the relevant authentication token, so I get an error. Seemingly for other, non-http-aware programs, dolphin is still able to open files with them via kio-fuse and presumably this would also work with LibreOffice, except for the fact that there doesn't seem to be a way to enforce this behaviour. I see a couple of solutions to this. One would be to allow users to turn on/off this behaviour in some way. This could be done globally (i.e. "never open http links with LibreOffice") or just for the individual remote folder. Alternatively, I suppose dolphin could try to detect when it is unlikely that the file will be available on the public web (e.g. by checking whether or not authentication was required to access it) and change its behaviour accordingly. This option seems harder. See attachment for screenshot of error. STEPS TO REPRODUCE 1. Connect to a password-protected webdav instance through dolphin 2. Attempt to open a LibreOffice document OBSERVED RESULT Error displayed as LibreOffice fails to access URL. EXPECTED RESULT File opens normally (via kio-fuse?).
