Does exist a method more optimized than that?
It works for a few of records but not for a lot of records!!! :( I need to import 4000 records ...

private function importLDIF($file, $idAbook){
$rows = $this->LDIFParser( $file );

foreach($rows as $row){
$contact['addressbook_id'] = $idAbook;

foreach($row as $k=>$v){
switch($k){
case 'givenName': $contact['nome'] = $v; break;
case 'sn': $contact['cognome'] = $v; break
......
}
}

$this->Contact->newRecord($contact);
$this->Contact->save();
}
}
