On the development machine we have the default certificates that comes with apache, when we trying to authenticate with facebook, HWIOAuthBundle fires an exception:
SSL certificate problem: unable to get local issuer certificate
It's clear that in plain PHP we need to set an option CURLOPT_SSL_VERIFYPEER = false, and pass to curl_setopt_array(...).
How can we define these options for Symfony or for HWIOAuthBundle?
Add following options under "hwi_oauth" and you should be fine.
hwi_oauth:
http_client:
verify_peer: false
