ForgeRock OpenIG as OAuth 2.0 Resource Server

First things first, screen-cast that follows this write up is based on the ForgeRock documentation on OpenIG that’s found here. Secondly, if you aren’t familiar with ForgeRock OpenIG or ForgeRock OpenAM, I’d recommend you to do some reading on the products from the official ForgeRock documentation or watch the following screen-casts on it to become familiarized with it:

Cut to present, we have OpenIG acting as a resource server. So in the video log, you’ll see the curl command being used to contact OpenAM to get an Access Token, use the same command to contact OpenIG with the Access Token, which is when OpenIG (acting as a resource server), will contact OpenAM (acting as an authorization server) for validating the token. Once validated, OpenIG will apply additional filters to post the credentials to a HTTP Server and get the user profile in response to it.A one-liner definition for the mouthful of jargon I used above can be found here. The illustration below might make the long story said above slightly shorter.
