 * Processes the request to log in. Authorizes the given credentials and if they match a user,
 * stores the user into the session (keys <code>loggedUserId</code>, <code>loggedUserName</code>,

 * If the session contains a <code>loginRedirectUrl</code> key, redirects the user to that URL.
 * Otherwise, redirects back to the index page of the application.
 * <p/>
 * If the user is already logged in or the authentication fails, a <code>PyramusRuntimeException</code>
 * is thrown with a localized message stating so.
