OmniAuth & Facebook: certificate verify failed

Question

I've followed Railscast #235 to try and set up a minimal Facebook authentication.

I've first set up a Twitter authentication, as done by Ryan himself. That worked flawlessly.

I then moved on to adding a Facebook login. However, after authorizing the app the redirect to /auth/facebook/callback fails with:

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

I am working on localhost. I didn't set up any SSL within the app. What am I doing wrong?

Answer 1

This seems to be a 1.9.x issue. Reverting to 1.8.7 fixed the issue.
