I think this has been fixed now in 3.1@dev. Can you confirm?

This should be fixed, indeed.

Also, as a reminder, the LdapClient class should not be used unless you need it for backward compatibility reasons.

Yep, it's fixed in the dev version, I didn't saw it.

LdapClient now calls the normalizeConfig() method, which maps the LdapClient constructor parameters to the AbstractConnection configuration format.

@csarrazi I didn't used LdapClient, it was for the demonstration purpose, in my case it was happening when trying to login with a "form_login_ldap" firewall.

Okay!
Thanks for the confirmation, by the way! :)

@Julien-Marcou : can you share example of services.yml which uses Symfony\Component\Ldap\Ldap
Unfortutnently symfony doc and cookbooks are outdated (i'm using 3.1), and i wasn't able figure it out by myself :(

The docs haven't been updated for 3.1 yet, indeed.

For an example:

ldap:
        class: Symfony\Component\Ldap\Ldap
        factory: [ 'Symfony\Component\Ldap\Ldap', 'create']
        arguments:
            - ext_ldap
            - host: ldap.forumsys.com
              debug: true

In short:

• You should use the Ldap::create() factory to create your service.
• There are two arguments:
  • The string associated to the adapter you wish to use. Only one is supported for now, which is ext_ldap.
  • The options array.

Some options are global (host, port, encryption, version, connection_string). Options specific to the implementation (ext_ldap) are also present in the main array (debug, for example, which is a shorthand for increasing verbosity for error messages), as well as the options sub-array (you may actually pass any option as defined in the ConnectionOptions class, using snake_case.

E.g.

<?php
use Symfony\Component\Ldap\Ldap;

$ldap = Ldap::create('ext_ldap', array(
    'host' => 'my-ldap-host',
    'encryption' => 'ssl',
    'version' => 3,
    'debug' => true,
    'options' => array(
        'timelimit' => 2,
        'sizelimit' => 5,
        'network_timeout' => 10,
        'referrals' => true,
    ),
));

In Symfony 3.1.6 get LDAP instance should like this:

        $config=[
            "connection_string"=>"ldaps://dev-env.com",
            "port"=>555,
            "version"=>3,
            "encryption"=>'ssl',
            "debug"=>true,
        ];
$ldap = Ldap::create("ext_ldap",$config);
$ldap->bind($bindUser, $bindUserPassword);
$data=$ldap->query($ldapBaseDn,$filter);

config "host" key is not working.

You should not use connection_string in combination with either host or port.
I will update the code so that an exception is thrown if it is the case.

You should either change your configuration and use host instead of connection_string (with the value dev-env.com), or remove the port option, and only use a connection string with the port inside (i.e. ldaps://dev-env.com:555).

In short, host + port and connection_string are intended to be mutually exclusive.
