Hi,

I’ve discourse hosted at `http://a.com`

I am hosting the same discourse instance at `http://b.com`

would there be some config to make SSO works? Such that when a user clicks login from [b.com](http://b.com), it will be redirected back to [b.com](http://b.com)?

You should not serve the same site on multiple domains. Google doesn’t like that.
