KDE Dolphin fails to mount SMB shares with samba version version
4.15.7+git.376.dd43aca9ab2 installed. My target system is a NAS system with NT1
support enabled.

When I try to access it, which worked before update of samba, I now get the
error message from Dolphin if I want to list the shares:
Die Datei oder der Ordner smb://myserver/ existiert nicht.
or when I try to access the share directly:
Die Datei oder der Ordner smb://myserver/myshare existiert nicht.

Please see the identified upstream bug:

https://bugs.kde.org/show_bug.cgi?id=453090

To mitigate the bug, if you set username and password in the URL upfront, the
request then works, as the access denied error is not triggered. E.g.
smb://myself:myverysecurepassword@myserver

A similar problem was reported for Gnome in Bug #1198718.

The issue was also reported to the samba team in ticket.
https://bugzilla.samba.org/show_bug.cgi?id=14983

The samba team will not change something so Gnome and KDE have to adopt their
code. I raised this ticket, so that please the KDE patch will also be made
available to the current Leap version as the Gnome patch will be done.

Thanks
