Magento can't login in admin with right username and password

Question

I just freshly installed Magento(1.7.0.2) on my localhost(LAMP). Now after installation when I wanted to go for the admin panel it asked me for the username and password. Although I used right username and password still its showing Invalid User Name or Password. I made clear my browser cookie but again it showed me the same problem with login. I searched over google and got something that I can login using http://127.0.0.1 instead of http://localhost. But it still not working for me. I have searched over google whole day and as pe some blogs have told that just make some line comments in varien.php file, I also made comments in varien.php file but still its not working for me(as here I am using 1.7.0.2 and in blogs they have told about 1.6.X ). I have installed magento 4 times today already but still I am facing the same problem again and again. Can someone tell me how to solve this? Any help and suggestions will be really appreciable.

If you are having trouble to get logged in with the correct username and password, here are some ideas. If you have used google chrome to install magento, use firefox to open magento and edit the app/code/core/Mage/Core/Model/Session/Abstract/Varien.php file within your magento directory and comment those below lines

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

And use your credentials to log in. I hope this works for you!!!
