How to set a custom option in env ?

[evifere]

I would like to add an env variable which would be called LDAP_{name}_IDENTIFIER_ATTRIBUTE.

I have a custom LDAPCustomServiceProvider which look like this.

<?php
namespace App\Providers;

use App\Helpers\Env;
use LdapRecord\Lumen\LdapServiceProvider;

class LDAPCustomServiceProvider extends LdapServiceProvider{

    /**
     * Make a connection's configuration from the connection's environment name.
     *
     * @param string $connection
     *
     * @return array
     */
    protected function makeConnectionConfigFromEnv($connection)
    {
        return array_filter([
            'hosts' => explode(',', env($this->makeEnvVariable('LDAP_{name}_HOSTS', $connection))),
            'username' => env($this->makeEnvVariable('LDAP_{name}_USERNAME', $connection)),
            'password' => Env::env_password($this->makeEnvVariable('LDAP_{name}_PASSWORD', $connection)),
            'port' => env($this->makeEnvVariable('LDAP_{name}_PORT', $connection), 389),
            'base_dn' => env($this->makeEnvVariable('LDAP_{name}_BASE_DN', $connection)),
            'timeout' => env($this->makeEnvVariable('LDAP_{name}_TIMEOUT', $connection), 5),
            'use_ssl' => env($this->makeEnvVariable('LDAP_{name}_SSL', $connection), false),
            'use_tls' => env($this->makeEnvVariable('LDAP_{name}_TLS', $connection), false),
            'identifier_attribute' => env($this->makeEnvVariable('LDAP_{name}_IDENTIFIER_ATTRIBUTE', $connection), 'sAMACcountName'),
            'options' => $this->makeCustomOptionsFromEnv($connection),
        ]);
    }
}

Unfortunattely when i try to run it i have the following error

Option identifier_attribute does not exist.

\vendor\\directorytree\\ldaprecord\\src\\Configuration\\DomainConfiguration.php line 134

I see that there is an extend method in DomainConfiguration but i don't understand how to use it.

Thanks in advance for your help.

find a solution by overriding makeConnection

    /**
     * Make a new LDAP connection.
     *
     * @param array $config
     *
     * @return Connection
     */
    protected function makeConnection($config)
    {
        DomainConfiguration::extend('identifier_attribute','sAMAccountName');
        return  app(Connection::class, ['config' => $config]);
    }

Hopes this is the proper way to use the method extend.
