Log in to Zoho Support with Google Apps

Hi there!

I see "sign in with Google Apps" options and Google Marketplace apps for Zoho Support, but I have a feeling I can't clearly answer my simple question:

Is it possible to have users from a Google Apps domain sign in with their google apps credentials to the Zoho Support Customer Portal?

I should mention I'm currently on the Free Plan, but am ready to upgrade if that means simplified sign-in =)

Thanks!
