Request New Password - process/flow change?

Hi,

thank you for your reply.

I have updated the function as follows:

function m2f_password_reset_form_alter(&$form, &$form_state) {
  if ($form['#action'] == "/user/password"){
  print("<pre>");
  var_dump($form_state);
  print("</pre>");
  $form_state['redirect'] = "node/20";
  print("<pre>");
  var_dump($form_state);
  print("</pre>");
  }
}

The second var_dump($form_state) output is

array(13) {
  ["build_info"]=>
    array(2) {
      ["args"]=> array(0) { }
      ["files"]=> array(1) {
          ["menu"]=> string(27) "modules/user/user.pages.inc"
        }
    }
  ["rebuild"]=> bool(false)
  ["rebuild_info"]=> array(0) {  }
  ["redirect"]=> string(7) "node/20"
  ["temporary"]=>  array(0) {}
  ["submitted"]=> bool(false)
  ["executed"]=>  bool(false)
  ["programmed"]=>  bool(false)
  ["cache"]=> bool(false)
  ["method"]=>  string(4) "post"
  ["groups"]=>  array(0) { }
  ["buttons"]=>  array(0) { }
  ["input"]=> array(0) { }
}

The only difference between the first and second var_dump() is
first output
["redirect"]=> NULL
second output
["redirect"]=> string(7) "node/20"

I have tried using various permutations of:
$form_state['redirect'] = "node/20";

$form_state['redirect'] = "/node/20";
$form_state['redirect'] = "http://www.domain.com/node/20";
$form_state['redirect'] = "url_alias name";
$form_state['redirect'] = "/url_alias name";
$form_state['redirect'] = "http://www.domain.com/url_alias name";

and so on, but each time I do a new password request, the form processes and end up at
/user

with the green message saying the email has been sent.

I have checked the triggers that prevent redirection on the link sent through drupal_redirect_form()

If $form_state['redirect'] is FALSE, a form builder function or form validation/submit handler does not want a user to be redirected, which means that drupal_goto() is not invoked.
If $form_state['no_redirect'] is TRUE, then the callback that originally built the form explicitly disallows any redirection, regardless of the redirection value in $form_state['redirect'].
If $form_state['programmed'] is TRUE, the form submission was usually invoked via drupal_form_submit(), so any redirection would break the script that invoked drupal_form_submit().
If $form_state['rebuild'] is TRUE, the form needs to be rebuilt without redirection.

And the var_dump() does not look to meet any of these.

Any idea what I have missed?

Thank you for your help
