The authorization server provides an OAuth token to a client when presented with a set of valid credentials. The generated OAuth token can be used to authorize subsequent requests to the SmartPlant Foundation Server API.
There are currently two implementations commonly used in a SmartPlant Foundation reference architecture:
Intergraph Authorization Server - provided as part of the SmartPlant Foundation installation and uses either SmartPlant Foundation credentials or Windows Authentication to generate a valid OAuth token for subsequent requests.
Smart API Manager (SAM) - provided independently of SmartPlant Foundation and provides more extensive Authorization Server capabilities, as well as integration to other identity providers.
