OmniAuth IndieAuth

This is an OmniAuth strategy for using IndieAuth.com as an authentication server.

Basic Usage

use OmniAuth::Builder do
  provider :indieauth, :client_id => 'http://example.com'
end

Using a Custom Auth Server

use OmniAuth::Builder do
  provider :indieauth, :client_id => 'http://example.com', :server => 'https://indieauth.com'
end

Profile Info

After the user signs in, the uid reported by OmniAuth will be their URL they entered. The gem will also attempt to parse their URL for an h-card, and return their real name and profile image if available.
