Managing RBAC Cross Multiple Kubernetes Clusters

Rancher implements a Kubernetes-native authn/authz layer using CRDs and custom controllers to manage users, groups and permissions across many clusters, with one central auth proxy that performs service-account impersonation to call member clusters. It adds a global role above cluster roles and a project grouping CRD that bundles namespaces so RBAC, PodSecurity and NetworkPolicy inherit automatically; roles and bindings are created/removed by controllers on add/remove events, and demos show cluster import, GitHub/LDAP/AD integration and live propagation working end-to-end.
