Access G+ Communities from a Person

Question

I want to authenticate users by their membership in a closed community in G+

Is there a way to get:

1. The communities of a user
2. The members within a community

Both ways would be fine.

I am through the whole documentation (which isn't that much) and haven't found a solution for this problem.

Answer 1

No, there is no support for communities as part of the Plus API right now.
