Query LDAP server

[nodi]

Hi all 🙂

How can i perform a query for existe username and valid password , I found this example but i don't know what is DC,CN etc ..

<?php
$ldapServer = '127.0.0.1';
$ldapBase = 'DC=anlx,DC=net';

/*
 * try to connect to the server
 */
$ldapConn = ldap_connect($ldapServer);
if (!$ldapConn)
{
  die('Cannot Connect to LDAP server');
}

/*
 * bind anonymously
 */
$ldapBind = ldap_bind($ldapConn);
if (!$ldapBind)
{
  die('Cannot Bind to LDAP server');
}

/*
 * set the ldap options
 */
ldap_set_option($ldapConn, LDAP_OPT_PROTOCOL_VERSION, 3);

/*
 * search the LDAP server
 */
$ldapSearch = ldap_search($ldapConn, $ldapBase, "(cn=*)");
$ldapResults = ldap_get_entries($ldapConn, $ldapSearch);

for ($item = 0; $item < $ldapResults['count']; $item++)
{
  for ($attribute = 0; $attribute < $ldapResults[$item]['count']; $attribute++)
  {
   $data = $ldapResults[$item][$attribute];
   echo $data.":&nbsp;&nbsp;".$ldapResults[$item][$data][0]."<br>";
  }
  echo '<hr />';
}

?>
