[keycloak-user] Native App Authorization with multiple Identity Providers

I'm trying to: 1) Use Facebook as an initial Identity Provider for a native app 2) Have the native app pass it's access token back to a service which would then retrieve the fb_exchange_token. Another service would then retrieve additional information back from Facebook via the approved scopes. 3) Have an option to use LinkedIn to provide additional information about the user, so have it as an addtional supplemental identity provider. 4) Have the native app pass the token back to a service. Another service would retrieve additional information from LinkedIn to supplement the users profile. I'd like to know how much of this functionality Keycloak can provide. Should I be using aerogear-ios-oauth2 configured with Facebook and LinkedIn providers, or configuring aerogear-ios-oauth2 with a keycloak provider & configuring Facebook and LinkedIn as provider there? Any assistance appreciated! mW
