Description kskot 2024-06-19 13:51:48 UTC

SUMMARY
I have a network directory mounted in Dolphin via SFTP, which is authenticated with my ssh keys. Before the update of neon to Plasma 6.1 and frameworks 6.3, I was able to open and stream video files from Dolphin with VLC without entering credentials. Now I'm asked for a user and password. 

This bug looks similar to https://bugs.kde.org/show_bug.cgi?id=485068, but in my case the files are showing fine in Dolphin, but applications started from dolphin are having trouble accessing the data.

OBSERVED RESULT
Need to input user and password to be a

EXPECTED RESULT
Not needing to supply additional authentication details, when SSh keys are already configured and used.

Please attach a screenshot of the auth dialog you are seeing in vlc.

VLC auth dialog

Comment 4 kskot 2024-06-21 19:16:07 UTC

VLC version: 3.0.16 (native package, not flatpak)

Comment 5 Harald Sitter 2024-06-21 20:12:42 UTC

That's VLCs auth dialog, means the sftp worker from kio isn't even involved. Moving to dolphin for more investigation.

Comment 6 kskot 2024-06-21 23:01:57 UTC

The dolphin version did not change in the neon update, only plasma and frameworks got updated. It worked fine before the update. So I think the issue is likely somewhere in frameworks.

no idea why, but the problem went away when switching from RSA to ED25519 keys.
