Google OpenID not working with OpenID plugin in WordPress

Question

The OpenID plugin for WordPress does not seem to accept any of the links from the Google OpenID provider:

http://google.com/profiles/username

or

https://google.com/accounts/o8/id

It returns an error (for both):

Could not discover an OpenID
identity server endpoint 
at the url:
http://google.com/profiles/username

Any idea why? Janrain uses the plugin, but I can not use it because of other problems with this.

Answer 1

The problem is resolved. Because Google, Yahoo, and some other OpenID providers provide https endpoints, curl tries to check the other end when executing a POST request, because curl does not come with a CA certificate package, it does not work on all such endpoints.

, curl, CA Google.

Answer 2

CA . Google .

Answer 5

I was getting the same error and checking apache error logs. I got the following

CURL error (60): SSL certificate problem: unable to get local issuer certificate

This is caused by calls curlfrom the OpenID plugin.

The following worked for me. Source: fooobar.com/questions/91737 / ...

• Use this root certificate certificate kit: https://curl.haxx.se/ca/cacert.pem

• Copy this set of certificates to your disk. And use it onphp.ini

  curl.cainfo = "path_to_cert\cacert.pem"

Be sure to restart the server after making the changes.
