mappu no, G2 is it's own root, but there are ways to get it to work -- but it's rather impractical for deployed applications to public users, etc. They expect it to "just work". So, as the post mentions... the current only work-around is to get a SHA-1 cert from Godaddy's Class 2 CA server (which sings all SHA-1 certs).

I really think people need to dog on Godaddy more about this. It's not really excusable to be a half-assed CA today...
