Symfony - Ldap create don't connect to serveur-CodePudding

With the PHP function ldap_connect it's working:

My controller :

/**
* @Route("/ldap", name="ldap")
*/
public function ldap(Request $request) {
    $ldaprdn  = 'cn=read-only-admin,dc=example,dc=com';    
    $ldappass = 'password';  

    $ldapconn = ldap_connect("ldap://ldap.forumsys.com")
        or die("Impossible de se connecter au serveur LDAP.");

    if ($ldapconn) {

        ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);

        // Connexion au serveur LDAP
        $ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
        var_dump($ldapbind); 

        // Vérification de l'authentification
        if ($ldapbind) {
            echo "Connexion LDAP OK ...";
        } else {
            echo "Connexion LDAP KO ...";
        }
    }
}

Result : bool(true)

But if I use Symfony Ldap it's don't work, did you know why ?

My controller :

use Symfony\Component\Ldap\Ldap;

[...]

/**
* @Route("/ldap", name="ldap")
*/
public function ldap(Request $request) {
    $host = 'ldap.forumsys.com';
    $port = 389;
    $version = 3;
    $dn  = 'cn=read-only-admin,dc=example,dc=com';
    $pwd = 'password';
    
    $ldap = Ldap::create('ext_ldap', [ 
        'host' => $host,
        'port' => $port,
        'version' => $version,
    ]);
    
    $ldap->bind($dn, $pwd);
    var_dump($ldap); 
}

Result :

["connection":"Symfony\Component\Ldap\Adapter\ExtLdap\Connection":private]=> resource(31) of type (ldap link) ["config":protected]=> array(8) { ["host"]=> string(17) "ldap.forumsys.com" ["version"]=> int(3) ["encryption"]=> string(4) "none" ["port"]=> int(389) ["connection_string"]=> string(28) "ldap://ldap.forumsys.com:389" ["debug"]=> bool(false) ["referrals"]=> bool(false) ["options"]=> array(3) { ["network_timeout"]=> string(2) "60" ["protocol_version"]=> int(3) ["referrals"]=> bool(false) } } } ["entryManager":"Symfony\Component\Ldap\Adapter\ExtLdap\Adapter":private]=> NULL } }

I use an online Ldap test server

CodePudding user response：

It actually works, it seems like you don't really know how to use it.

Please, read: The Ldap Component

While ldap_bind returns false when authentication was unsuccessful, Symfony Ldap component's bind method returns nothing on success and throws an exception on error (which you can see from the source code). In your case, you must check if the connection/authentication was successful with a try/catch block:

<?php

use Symfony\Component\Ldap\Exception\ConnectionException;

try {
    $ldap->bind($dn, $pwd);
} catch (ConnectionException $exception) {
    // Error message based on your original code
    echo 'Connexion LDAP KO:' . $exception->getMessage();
}
