Identity & Authentication

What problem does it solve?

Identity management and authentication systems are complex, requiring integration across identity providers, policy engines, and secret stores; this skill provides guidance for configuring Keycloak realms and clients, authoring OPA policies, and managing Vault secrets to enable robust RBAC/ABAC and secure access flows.

Core Features & Use Cases

• Keycloak admin CLI (kcadm) usage for realms, clients, users, and roles
• OPA policy basics, evaluation, and testing
• Vault operations including AppRole, secret engines, and dynamic credentials
• OIDC/OAuth2 flows and token validation integration
• Integration patterns such as JWT validation and OPA sidecar deployment

Quick Start

Configure a Keycloak realm with a client, create a simple OPA policy, and set up Vault AppRole in a dev environment to begin securing identities.
