You can achieve Single Sign On with Google Apps using the OpenID Plugin. It's very easy to set up, you basically install the plugin, select "Google Apps SSO (with OpenID)" and enter your domain. Note that users will have to have a google apps account to login after that.
Tip: you might consider using it in combination with the Role Strategy Plugin
