Janrain's PHP-OpenID and Google/Yahoo

Ok, I finally got to fix the library... I explained everything here (you can also download the php-openid library after my changes).

I needed to do what Paul Tarjan suggested but, also, I needed to modify the Auth_OpenID_detectMathLibrary and add the static keyword to a lot of functions. After that It seems to work perfectly although it is not an ideal solution... I think that someone should rewrite the whole library in PHP 5...

I had the same problem on Windows XP. Fixed by activating curl extension. To do this uncomment in php.ini the line

extension=php_curl.dll

by removing the ; in front of it if any. Restart apache.

Also on windows to work properly you need to define Auth_OpenID_RAND_SOURCE as null since in windows you don't have a random source. You can do this by adding the line

define('Auth_OpenID_RAND_SOURCE', null);

in CryptUtil.php before the first code line

if(!defined('Auth_OpenID_RAND_SOURCE')){

Even if the curl is not enabled the API should work by using instead the Auth_Yadis_PlainHTTPFetcher to communicat via HTTP. In the case of Google and Yahoo you need https, so it only works if open_ssl is enabled (Auth_Yadis_PlainHTTPFetcher::supportsSSL must return true).

I had exactly the same problem and it took me nearly 2 hours to track the problem. Jan Rain's OpenId lib requires 'DOM or domxml PHP XML' (https://github.com/openid/php-openid) but it will fail silently when neither is available!

On my CentOS installation simple:

yum install php-xml

fixed the problem (I'm using this repo: http://blog.famillecollet.com/pages/Config-en).
