Magento admin login issues

The solution for this modify the core Magento code. Open the page app/code/core/Mage/Core/Model/Session/Abstract/Varien.php. Comment out the lines 80 to 83. The line number may vary according to the Magento version. But these lines are present somewhere near line 80.

You have to comment the comma (,) in line:

$this->getCookie()->getPath()//,

// set session cookie params

session_set_cookie_params(

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

$this->getCookie()->getPath()//,

//$this->getCookie()->getDomain(),

//$this->getCookie()->isSecure(),

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

);

Well, I am out of this problem. Hope, this solution you also help you.
Update (For Magento 1.4.*)
In Magento 1.4, you have to comment code from line 86 to 98 in app/code/core/Mage/Core/Model/Session/Abstract/Varien.php. Like this:-

/* if (!$cookieParams['httponly']) {

unset($cookieParams['httponly']);

if (!$cookieParams['secure']) {

unset($cookieParams['secure']);

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

unset($cookieParams['domain']);

}

}

}

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

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

} */
