Redirect Fisrt time login with LDAP
Thanks for your answers, I could do it, no with Rules module. I did it using hook_user_login(), and $_GET['destination'].

    function webform_sub_user_login(&amp;$edit, $account) {
    $currentuser = $edit['uid'];
    $_GET['destination']= "/user/".$currentuser."/edit";
    }


If it can cause problems, let me know. But for now it seems to work well.
