I am using JanRain OpenID Library PHP. I am trying out the consumer example in /example/consumer. Services like Google (or Yahoo) are not working, while other's like myopenid.com, blogger are working. My PHPinfo says that cURL and OpenSSL is enabled. Note that I also tried using LightOpenID Library (gitorious.org/lightopenid) which works with Google. Unfortunately, it doesn't work on server with php safe_mode On, it requires cURL. So I cannot use on all servers. JanRain's Library works on the server but not with Google.
