Whether I tried from a client like RapidSVN or from the command line, this is the error I got:
svn: Can’t create tunnel: The system cannot find the file specified.
It would have been helpful if the message mentioned what file it was looking for, but whatever…
…even more surprisingly, google-ing didn’t turn up a solution either…
Luckily I remembered something about plink.exe …
The second obstacle was finding the right way to specify the path to plink.exe
I added the environmental variable:
Yes, the path is unix style and NOT windows style.
And yes, the path is enclosed in double quotes (because of the space in it).
