The various validators shipped in ZF are not "context-aware" -- i.e.,
they operate only on the value passed to them.

I would write a custom validator for this that checks the password field
against the repassword field, and attach it to your password field. It
might look like this:

Custom_Validate_PasswordCheck extends Zend_Validate_Abstract
{
const NO_CONTEXT = "cvpNoContext";
const NO_CONTEXT_KEY = "cvpNoContextKey";
const NOT_IDENTICAL = "cvpNotIdentical";

protected $_contextKey = 'repassword';

protected $_messageTemplates = array(
self::NO_CONTEXT => 'No context was provided to the validator',
self::NO_CONTEXT_KEY => 'No matching field was found in the context against which to validate',
self::NOT_IDENTICAL => 'The password validation does not match',
);

public function __construct($options = null)
{
if (is_string($options)) {
$this->_contextKey = $options;
} elseif (is_array($options) && isset($options['contextKey'])) {
$this->_contextKey = $options['contextKey'];
}
}

public function isValid($value, $context = null)
{
if (!is_array($context)) {
$this->_error(self::NO_CONTEXT);
return false;
}

if (!isset($context[$this->_contextKey])) {
$this->_error(self::NO_CONTEXT_KEY);
return false;
}

$compare = $context[$this->_contextKey];
if ($value != $compare) {
$this->_error(self::NOT_IDENTICAL);
return false;
}

return true;
}
}

Place the above in Custom/Validate/PasswordCheck.php on your
include_path.

Now, define your element as follows:

$element->addPrefixPath('Custom_Validate', 'Custom/Validate/', 'validate')
->set

$this->addElement('password', 'password', array(
'required' => true,
'maxlength' => 15,
'title' => 'Sono ammessi solamente caratteri alfanumerici e @,#,*',
'label' => 'form_User_Register_Label_Password',
'filters' => array('StringTrim'),
'prefixPath' => array(
'validate' => array(
'prefix' => 'Custom_Validate',
'path' => 'Custom/Validate',
),
),
'validators' => array(
array('stringLength',true, array(2, 25)),
array('regex', false, array('#^[^\.<>{};:"£$%\/^&()_\+\-=\]\[]+#'))),
'PasswordCheck',
));

You won't need a validator on the "repassword" element, as if it doesn't
match the password, it's obviously failed the password criteria as well.
