title: Using OpenID (gmail) to authenticate a user to a drupal site
body: <p>I want to develop a Drupal site, where I want to provide the user with a login screen. The user will be authenticated if they enter a valid gmail username/password, and will be taken to the main page from there. I believe I can use OpenID for this, but I am kind of lost on the specifics of how to use it. Any help will be appreciated.</p>
