I am using Authlogic-Connect for third party logins. After running appropriate migrations, Twitter/Google/yahoo logins seem to work fine but the facebook login throws except
I ran into a similar problem when trying to use the JQuery generator for Rails 3
I solved it like this:
Get the CURL Certificate Authority (CA) bundle. You can do this with:
sudo port install curl-ca-bundle [if you are using MacPorts]wget http://curl.haxx.se/ca/cacert.pemExecute the ruby code that is trying to verify the SSL certification: SSL_CERT_FILE=/opt/local/etc/certs/cacert.pem rails generate jquery:install. In your case, you want to either set this as an environment variable somewhere the server picks it up or add something like ENV['SSL_CERT_FILE'] = /path/to/your/new/cacert.pem in your environment.rb file.
You can also just install the CA files (I haven't tried this) to the OS -- there are lengthy instructions here -- this should work in a similar fashion, but I have not tried this personally.
Basically, the issue you are hitting is that some web service is responding with a certificate signed against a CA that OpenSSL cannot verify.
