ZendFatal error: Class 'Zend\Ldap\Ldap' no

Question

So, i'm trying to make a Ldap authentication, following the docs in

https://zf2.readthedocs.org/en/latest/user-guide/skeleton-application.html

I just replace the 'Album' module with a 'Auth' module and use the sample code for Ldap autentication

https://zf2.readthedocs.org/en/latest/modules/zend.authentication.adapter.ldap.html

but i'm getting this error where Zend can't find the Ldap class when i submit the form with the login data.

Fatal error: Class 'Zend\Ldap\Ldap' not found in C:\wamp\www\sade\vendor\zendframework\zend-authentication\src\Adapter\Ldap.php on line 139

I'm using composer, for the zend framework and the atuoloader for the modules, i already have errors related a class not found but my own classes, not Zend classes like Ldap.

Thanks.

Here is the structure of the files and folders

/module
     /Auth
         /config
            module.config.php
         /src
             /Auth
                 /Controller
                    AuthController.php
                 /Form
                    AuthForm.php
                 /Model
                 Auth.php
         /view
             /auth
                 /auth
                    index.php
        Module.php

And the main code of the module:

module.config.php

                     'id'     => '[0-9]+',

Auth.php (inside Model folder, for filters that i may implement later)

 class Auth implements InputFilterAwareInterface

 {
     $this->username = (isset($data['username'])) ? $data['username'] : null;
     $this->password  = (isset($data['password']))  ? $data['password']  : null;
 }

 // Add content to these methods:
 public function setInputFilter(InputFilterInterface $inputFilter)
 {
     throw new \Exception("Not used");
 }

 public function getInputFilter()
 {
     if (!$this->inputFilter) {
         $inputFilter = new InputFilter();

         $inputFilter->add(array(
             'name'     => 'username',
             'required' => true,
             'filters'  => array(

                     ),
                 ),
             ),
         ));

         $this->inputFilter = $inputFilter;
     }

     return $this->inputFilter;
 }
}

And Module.php, i don't think that index.phtml needs to be posted here.

 namespace Auth;

 use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
 use Zend\ModuleManager\Feature\ConfigProviderInterface;

 class Module implements AutoloaderProviderInterface, ConfigProviderInterface
 {
 public function getAutoloaderConfig()
 {

 }

 public function getConfig()
 {
     return include __DIR__ . '/config/module.config.php';
 }
 }

Answer 1

Zend\Ldap is not included any more in a default installation. As the ZendFramework-Team has splitted the zendframework into multiple components not all of them are needed any more. And Zend\Ldap is one of the "not needed" ones as it has a hard dependency on ext/ldap as you can't use it without the LDAP-extension of PHP. For details on that have a look at https://github.com/zendframework/zf2/issues/7569

You should therefore run composer require zendframework/zend-ldap from the base-directory of your project and you should be up and running. By now you get that as a suggestions after the installation.

zendframework/zendframework suggests installing zendframework/zend-ldap (zend-ldap component ~2.5.0, if you need LDAP features)

Answer 2

LDAP is a part of core of zf2.

If you have problems with class Name, then you habe some problems with your autoloader config or with incorrect class name paths.
