Best SAML implementation for Laravel

@thewruck for logout functionality you can give logout routes like this

Route::get('/saml-logout', [UserAPIController::class, 'logout']);

Route::get('/saml-logout-acs', [UserAPIController::class, 'acsLogout']);

and in controller you can add code like

use OneLogin\Saml2\Auth as SAMLAUTH;

public function logout(Request $request)

{

    session_start();

    // Initialize the SAML authentication class

    $auth = new SAMLAUTH(config('php-saml'));

    // Send a SAML logout request to the IdP

    $logoutUrl = $auth->logout();

    auth()->logout();
    session()->flush();
    // Redirect to the IdP logout URL (or to a local page)
    return redirect($logoutUrl);
}

public function acsLogout(Request $request)

{ // Initialize the SAML authentication object

    $auth = new SAMLAUTH(config('php-saml')); // Use your SAML configuration

    // Process the logout response

    $url = $auth->processSLO(); // This will handle the response from the IdP
 
    if ($auth->getErrors()) {
        return 'Error processing SAML logout response';
    }
    // If successful, you can redirect the user to a page, like a home page or login page
    $url = $request->origin . '/en/auth/login';

    // Redirect to the IdP logout URL (or to a local page)
    return redirect($url);
}

don't forget to add logout callback url in php-saml config file as

//inside idp aray

'idp' => [

'singleLogoutService' => [

        'url' => 'abc.example.com/trust/saml2/http-redirect/slo/3605901', 

        'binding' => '"urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect',
    ],

]

and inside sp(service provider) array

'sp' => [

          'singleLogoutService' => [

    	  'url' => localhost/folder/public/api/saml-logout-acs',  

         // This should match your ACS route for logout
      

         'binding' => '"urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect',

 ],

]

now hit the route as

://localhost/folder/public/api/saml-logout
