No OpenID Server found at https://www.google.com/accounts/o8/id

StackOverflow https://stackoverflow.com/questions/13564011

Question

Interesting enough I am using the same .php scripts on two different servers (a.com, b.com) with different results, I guess those have different configurations. While on a.com I am able to go through SSO process nicely, the b.com throws "No OpenID Server found at https://www.google.com/accounts/o8/id".

my php script looks as following:

$openid = new LightOpenID($_SERVER["HTTP_HOST"]);
$openid->required = array
(
    'contact/email',
    'namePerson/first',
    'namePerson/last'
);
if(!$openid->mode)
{
    $openid->identity = 'https://www.google.com/accounts/o8/id';
    header('Location: ' . $openid->authUrl());
}

in b.com the line $openid->authUrl() throws an error saying: No OpenID Server found at https://www.google.com/accounts/o8/id

What server configuration may cause this isse?

Was it helpful?

Solution

Luckily, server admins were able to quickly discover the config difference in php configuration allow_url_fopen = 1 solved the issue

OTHER TIPS

Google has discontinued OpenID support and as of July 22nd 2015 has removed this endpoint.

The approved solution/answer has become obsolete.

Please migrate to OAuth. If using a client (javascript) login, this tutorial by google comes with a fully functional example.

this code below is another fully functional example (just tested it), but it goesone step further and integrates with a server side PHP script. please substitute your own CLIENT ID (as defined in your google developer console) and YOURDOMAIN.COM (in php).

and this is the php side to the jquery/ajax call (twoStep.php)

<?php

    $idToken = $_POST["idtoken"];
    $url = 'https://www.googleapis.com/oauth2/v3/tokeninfo?id_token='.$idToken;
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    $json = json_decode($response, true);
    curl_close($ch);

    $userEmail = $json["email"];
    $clientId = $json["azp"];
    print_r($json); // returns array console readable

?>

HINT 4 newbies: read console output by rightclicking on any element of the page and choosing "inspect element", then changing to CONSOLE tab.
