ldap_search com ldap_get_entries returns no value

Question

I’m making authentication via LDAP:

$server = '192.168.0.1';
$domain = '@meudom';
$port   = 389;
$auth_user  = 'usuario1';
$auth_pass  = '123';

$ldap_connection = ldap_connect($server, $port) or die('Erro na conexão');
if (!$ldap_connection) exit('Falha na conexão');

ldap_set_option($ldap_connection, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldap_connection, LDAP_OPT_REFERRALS, 0);

$bind = @ldap_bind($ldap_connection, $auth_user.$domain, $auth_pass);
if (!$bind) exit('Usuário e/ou senha incorreto(s)!');

$filter = "(uid={$auth_user})";
$result = ldap_search($ldap_connection, "(dc=meudom, dc=com)", $filter) or exit("Erro em search");
$entries = ldap_get_entries($ldap_connection, $result);

ldap_close($ldap_connection);

I’ve seen some examples in research, but all almost in a pattern.

Until the part of ldap_bind is authenticating perfectly.

What I would like, is to bring the user data, among other possible information, but in $filter, I have tested several ways:

• "(uid={$auth_user})"
• "(cn=*})"
• "(or=*})"
• etc.

Always the result of print_r($entries) is Array ( [count] => 0 ).

I don’t know if there’s really something wrong with the part about ldap_search or another place.

Answer 1

removes the parentheses in search

ldap_search($ldap_connection, "dc=meudom, dc=com", $filter) –
