Identity & Authentication

Configure Keycloak realms and clients for OIDC authentication using the Keycloak admin CLI (kcadm) to manage users, roles, and client settings. This approach provides practical commands for establishing secure OAuth2 flows and token validation endpoints.

Author and test OPA policies for RBAC and ABAC by writing Rego rules that evaluate user roles and attributes. OPA policy testing validates authorization logic locally before deploying the policy engine as a sidecar for JWT validation and access control.

Manage Vault secrets and dynamic credentials with AppRole by configuring secret engines and authentication roles. Vault operations automate the secret lifecycle, generating and rotating credentials securely for integrated systems without manual intervention.

Yes, you can integrate Keycloak token validation with an OPA sidecar deployment. This pattern validates JWT tokens issued by Keycloak at the network level, passing identity claims to OPA for real-time RBAC and ABAC policy evaluation.

Setting up identity workflows requires familiarity with Keycloak realm configuration, OPA policy evaluation, and Vault secret management. The skill provides practical examples and commands but assumes foundational knowledge of OIDC, OAuth2, and RBAC concepts.
