Login Problem with Magento admin Login after Installation?

Magento admin can't able to login after installtion,

Please follow the below simple steps,

1 - Go to www or htdocs folder
2 - Go through this directory /app/code/core/Mage/Core/Model/Session/Abstract/Varien.php under Magento Installtion Dir
3 - Open with your editior, go to the 108 line
4 - Comment the followng line and try it
 call_user_func_array('session_set_cookie_params', $cookieParams); -   /*call_user_func_array('session_set_cookie_params', $cookieParams);*/

 Now try with Login, still problem exits.

 Please go to line from 85 to 92 in magento (1.7.2 for my case). Like this

 // session cookie params
/* $cookieParams = array(
'lifetime' => $cookie->getLifetime(),
'path'     => $cookie->getPath(),
'domain'   => $cookie->getConfigDomain(),
'secure'   => $cookie->isSecure(),
'httponly' => $cookie->getHttponly()
);
 */

5 - Hopefully you can login with your Magento. Let me know still if you have any issues.
