Magento - Can't login to admin in localhost

I am currently working on magento version 1.3.2.4. When i login to admin, it looks like i have entered proper username and password because it doesn't show any error like "Invalid username or password". When i try with fake login I do get error. Even i am not getting any error it stays on the login page.

So, I had to go through code and comment out few lines after which I was able to login and access admin again.
app\code\core\Mage\Core\Model\Session\Abstract\Varien.php line 77: original:

// set session cookie params

session_set_cookie_params(

    $this->getCookie()->getLifetime(),

    $this->getCookie()->getPath(),

    $this->getCookie()->getDomain(),

    $this->getCookie()->isSecure(),

    $this->getCookie()->getHttponly()

);

Commented out three lines:

// set session cookie params

session_set_cookie_params(

    $this->getCookie()->getLifetime(),

    $this->getCookie()->getPath() /*,

    $this->getCookie()->getDomain(),

    $this->getCookie()->isSecure(),

    $this->getCookie()->getHttponly()*/

);

As, I am upgrading magento from old community to enterprise 1.11 version. When i needed to login to admin of enterprise version, i got same issues. But this time code was different, so this is what i needed to do to access magento enterprise admin again.
app\code\core\Mage\Core\Model\Session\Abstract\Varien.php change:

if (isset($cookieParams['domain'])) {

    $cookieParams['domain'] = $cookie->getDomain();

}

To

if (isset($cookieParams['domain']) && !in_array("127.0.0.1", self::getValidatorData())) {

    $cookieParams['domain'] = $cookie->getDomain();

}
