I guess this is consistent with my varying success with the bash test.
If it's dependent on timing, the NAS could have been doing different
things during the two tests, one that worked and one that failed.

Tested as before. Yes, this improves things. I now get to the dired
buffer! This dired buffer looks badly formatted in the way described
before, when I managed to connect with another user running bash.
A debug buffer was still created, it is available as
http://www.solarphysics.kva.se/~mats/debug4.txt
An error was echoed. I guess the info is in the debug buffer but here it
is from the *Messages* buffer as well:
----begin----
...
Loading tramp...done
Loading easymenu...done
Loading tramp...done
Loading time-date...done
Tramp: Opening connection for root@10.0.0.3 using scp...

Tramp: Sending command `ssh 10.0.0.3 -l root -q -e none && exit || exit'
Tramp: Waiting for prompts from remote shell
Tramp: Sending password
Tramp: Found remote shell prompt on `10.0.0.3'
File error: `getconf PATH' returns with error
Tramp: `getconf PATH' not successful, using default value "/bin:/usr/bin".
Making completion list...
Quit
Making completion list...
Wrote /home/mats/debug4.txt
byte-code: Beginning of buffer
----end----
Back to the badly formatted dired buffer: In addition to it looking
funny, completion to existing file names does not work. Neither does
clicking on the file names. It fails to open the file and an error is
echoed: "dired-get-file-for-visit: File no longer exists; type `g' to
update dired buffer"
Thanks for spending time on this!
