Ivanti Connect Secure with OAuth / OpenID Deployment Guide
OAuth is an open-standard authorization framework that describes how unrelated servers and services can safely allow authenticated access to their assets, without sharing the initial, related, or single logon credentials. OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. OpenID allows clients to verify the end user identity based on the authentication performed by an Authorization Server. OpenID can obtain basic profile information about the end user in an interoperable and REST-like manner.
