Integrating Cisco ACI with Microsoft Using OAuth2: A Step-by-Step Guide
In this video, we dive into a practical setup of integrating Cisco ACI with Microsoft Azure AD using OAuth2 for secure access management. Instead of focusing on OAuth2 theory, we walk you through each configuration step needed to enable seamless authentication and role-based access control for Cisco ACI. From setting up the necessary parameters to testing our configuration in Postman, you’ll learn how to generate and validate tokens, configure the Certificate Authority, and manage Redirect URIs to ensure secure communication between Cisco ACI and Azure AD. Watch along as we decode the tokens, explore ID tokens for group and role claims, and get a hands-on look at making this integration happen in real time. If you find this content helpful, please give it a thumbs up, subscribe for more network solution videos, and drop any questions in the comments. Enjoy, and let’s secure those networks!
