Re: "Permission denied" from dired, but not from ido completion in tramp

[Philipp Middendorf]

Hi,

attached is the gzipped tramp log (I hope file attachments work, otherwise tell 
me how to give the log to you - uncompressed it's 70MiB, compressed it's 4MiB) 
of what I did:

- via ido-find-file, navigate to /asap3/petra3/gpfs/p11/2024/data/11019260 
(which then presented me with a list files inside the directory "11019260", 
proving that you can access it with ido)
- I then pressed C-j to open the directory "11019260" in dired. This resulted 
in a permission denied error.

Cheers
Philipp
