[tor-onions] domain socket as HiddenServicePort target -- permissions!?

Ivan, David, thanks a lot! It works now.

I've created more tests and wrote a huge, detailed, now deleted mail,
but in the end it was this hint that brought me to the right track:

I use the tor project's debian package on the dev machine and it has
some AppArmor profiles. After simply adding

/srv/hstest/hstest.socket rw,

to the file /etc/apparmor.d/local/system_tor and reloading AppArmor it
works.

Relieved,
Johannes
