Create two domains for them, SSO is possible when there is dedicated URL (not na1.salesforce.com or ap1.salesforce.com).

One of them hosts community, let's just say https://sf9-dev-ed.my.salesforce.com holds the community. And other org, https://npr-dev-ed.my.salesforce.com, users want to use the community, this is where our SSO plays an important role in providing seamless navigation in between orgs. 3. Enable and create a communities in sf9 org. It is required to have a different domain name. In this example the domain name of the community is "sf9-comm-developer-edition.ap1.force.com". 4. Create a community here, with some meaningful name at the end. 5. Click "Edit", it takes you to community administrator set
