GPU clusters support external OIDC authentication for Kubernetes clusters

GPU clusters now support external OpenID Connect (OIDC) authentication, allowing each team member to access the cluster's Kubernetes API using their organization's identity provider: Google, Okta, Auth0, Microsoft Entra ID, and others.

With OIDC enabled, access is managed through standard Kubernetes RBAC: admins bind permissions to individual user identities, and each user authenticates via their browser using SSO. This replaces shared kubeconfig credentials with per-user tokens, per-user audit trails, and clean revocation. Currently this feature is only supported for Kubernetes clusters.

OIDC must be configured at cluster creation time. See Set up OIDC authentication for the full setup guide.
