Php versions – Issue with the implementation of the simplesamlphp library into my web application

I tried to implement the simplesamlphp library into my web application. But when I call the requireAuth() function I get a PHP fatal error message. Uncaught Exception: Loader: Illegal character in filename…..
It seems like he can’t resolve the Class SimpleSAMLModulesamlAuthSourceSP
But I don’t know why.
Does anyone have a idea how to fix this?
I already deleted the whole simplesamlphp installation and reinstalled it.

I use the following code:

require 'var/www/simplesamlphp/lib/_autoload.php';
$lAuthSrc = new SimpleSAMLAuthSimple('default-sp');
if (!$lAuthSrc->isAuthenticated()) {
  $lAuthSrc->requireAuth();
}
$lAttributes = $lAuthSrc -> getAttributes();
foreach($lAttributes as $lAttribute) {
  print_r($lAttribute);
}

Some additional informations:
The configured authentication source test works fine. If I login via the configured authentication source, everything works fine and I don’t get any error messages (the requireAuth() function don’t get called in this case).
I use the latest version of simplesamlphp v.1.18.3

If you need any more information, please let me know.

    Thank you all for your help. I discovered this morning the issue. The issue was the autoloader which I use for my own application. I registered the application autoloader in another file which gets executed before the code you see above. And simplesamlphp uses some conditions like:

    if (!class_exists($className))

    And beacuse I registered my application autoloader before the function class_exists checked if the class exists in my application. In my application I don't use namespaces and this was the issue.

    To fix this issue, I unregistered my application autoloader before using the simplesamlphp code and registered the autoloader again after the simplesamlphp code.

    I hope this will save some of you headaches.

    Honestly it looks like your path is messed up on the require… are you sure you should be using:

    require 'var/www/simplesamlphp/lib/_autoload.php';

    and not

    require '/var/www/simplesamlphp/lib/_autoload.php';

    Do you really have a ‘var/www’ subdirectory relative to the location of the script? That looks wrong to me. If you include that first / before var it makes that path absolute to the typical install location for SSP.
