@Rahul Katariya Thanks for posting your query on Microsoft Q&A.
You can use Azure Active Directory (Azure AD) to authenticate users to your AKS cluster using OpenID Connect (OIDC). I think the flow should look like this - To configure OIDC authentication, you need to create an Azure AD application and configure it to use your external identity provider as an authentication source. Then, configure the AKS cluster to use the Azure AD application for OIDC authentication.
See Azure AD workload identity. This authentication method integrates with the Kubernetes native capabilities to federate with any external identity providers on behalf of the application.
