If you are using cm redis session try this: (worked for me)

$sesId = isset($_COOKIE['adminhtml']) ? $_COOKIE['adminhtml'] : false ;
if($sesId){
    $session = Mage::getSingleton('core_mysql4/session')->read($sesId);
}
$loggedIn = false;
if($session)
{
    if(stristr($session,'Mage_Admin_Model_User'))
    {
        $loggedIn = true;
    }
}

var_dump($loggedIn);

because if you are using cm redis its rewrites db session module with its own model.
