[CentOS] Apache Redirects...

I'm trying to require SSL for drupal login and admin pages and it seems
that this should work but it doesn't redirect if added to httpd.conf or
to .htaccess (I've tried both)

  RewriteCond %{REQUEST_URI} ^/(user|admin)
  RewriteRule ^(.*)$ https://%{SERVER_NAME}/$1 [L,R]

Shouldn't this be enough so that the URL...(googling suggests that it
is)

http://cms.tobyhouse.com/user/login
is automatically redirected to
https://cms.tobyhouse.com/user/login

?
