Has any one got class.openid.php working with google openID?
I am trying to study class.openid.php because it is simpler and smaller than
class.openid.php does not work with google openID https://www.google.com/accounts/o8/id, prints to me such error:
ERROR CODE: OPENID_NOSERVERSFOUND
ERROR DESCRIPTION: Cannot find OpenID Server TAG on Identity page.
is it possible to make class.openid.php (any version) work with google openID and how to do such thing?
class.openid.php can be taken here but it did not worked for me out of the box so I had to find all <? and replace tham with <?php in case someone would like to see code I've got:
html interface page:
<?php
require('class.openid.v3.php');
if ($_POST['openid_action'] == "login"){ // Get identity from user and redirect browser to OpenID Server
$openid = new SimpleOpenID;
$openid->SetIdentity($_POST['openid_url']);
$openid->SetTrustRoot('http://' . $_SERVER["HTTP_HOST"]);
$openid->SetRequiredFields(array('email','fullname'));
$openid->SetOptionalFields(array('dob','gender','postcode','country','language','timezone'));
if ($openid->GetOpenIDServer()){
$openid->SetApprovedURL('http://' . $_SERVER["HTTP_HOST"] . $_SERVER["PATH_INFO"]); // Send Response from OpenID server to this script
$openid->Redirect(); // This will redirect user to OpenID Server
}else{
$error = $openid->GetError();
echo "ERROR CODE: " . $error['code'] . "<br>";
echo "ERROR DESCRIPTION: " . $error['description'] . "<br>";
}
exit;
}
else if($_GET['openid_mode'] == 'id_res'){ // Perform HTTP Request to OpenID server to validate key
$openid = new SimpleOpenID;
$openid->SetIdentity($_GET['openid_identity']);
$openid_validation_result = $openid->ValidateWithServer();
if ($openid_validation_result == true){ // OK HERE KEY IS VALID
echo "VALID";
}else if($openid->IsError() == true){ // ON THE WAY, WE GOT SOME ERROR
$error = $openid->GetError();
echo "ERROR CODE: " . $error['code'] . "<br>";

}else{ // Signature Verification Failed
echo "INVALID AUTHORIZATION";
}

The problem is that Google doesn't just supply an OpenID endpoint.
OpenId endpoints include an identifier for the user.
What we are having here is called a Discovery Url.
This is a static url that you can direct any user to, and the service itself will recognise the user and return a per-user unique identifying url.
This however is NOT implemented correctly by most openid client libraries, including the majority linked on the official openid website.
Even the Zend Framework libraries are incapable of handling that.
However I found a class that I analysed from various perspectives and that I am very satisfied with. At the company I work at we already integrated it successfully in several production environments and have not experienced any problems.
You may also be interested in another post of mine dealing with the issue of making Facebook an openid Provider. The class I am using, that also supports Google, can also be found there:
Best way to implement Single-Sign-On with all major providers?
The class in your question does not support OpenID 2.0 at all. Therefore, it will not work with Google without adding a lot of code.
Are you searching something like : http://wiki.openid.net/w/page/12995176/Libraries ?
There is a PHP section in that.
