Question

Anyone can help with this issue: I have simplesamlphp instaled and tested successfully with my IdP and SP. when I integrated the APP following the doc (step 6) https://simplesamlphp.org/docs/1.5/simplesamlphp-sp I started getting errors I will post bellow. Here is my autoload.php:

require __DIR__.'/../vendor/autoload.php';
require_once('/var/simplesamlphp/lib/_autoload.php');

$as = new SimpleSAML_Auth_Simple ( 'default-sp' );

if ($as->isAuthenticated ()) {
  //die ( 'ok' );
} else {
  $param = array (
    'ReturnTo' => 'http://10.128.240.181/'
  );
  $as->requireAuth ( $param );
}
$attributes = $as->getAttributes();
print_r($attributes);

$session = SimpleSAML_Session::getSessionFromRequest();
$session->cleanup();

Error output:

I think there are two issues. The first one is:

Feb 07 16:52:32 simplesamlphp WARNING [CL0a04f709] The class or interface 'SimpleSAML_Auth_Simple' is now using namespaces, please use 'SimpleSAML\Auth\Simple'.

It seems you are following an old documentation and using a recent version of SimpleSAMLphp. You will have to use $as = new \SimpleSAML\Auth\Simple('default-sp'); instead of $as = new SimpleSAML_Auth_Simple ( 'default-sp' );

If you are using the latest stable version of SimpleSAMLphp, please follow https://simplesamlphp.org/docs/stable/simplesamlphp-sp

The second issue is

****PHP Fatal error: Uncaught SimpleSAML_Error_UnserializableException: Unable to parse base url: http://localhost in /var/simplesamlphp/lib/SimpleSAML/Auth/Source.php:197****

This is more related to the configuration (This is a wild guess). Can you provide more info on your web server (IIS/Apache/nginx)? I think IIS has some known issues: https://github.com/simplesamlphp/simplesamlphp/issues/540
