…nshift#37) Add ValidateComponentPrivileges and privilegeRequirementsFor to the vsphere actuator package. Defines privilege requirement sets for all four CCO-managed components (machine-api, storage, cloud-controller, vsphere-problem-detector) and validates them through a PrivilegeChecker interface, enabling unit testing without a live vCenter. Authentication failures and missing-privilege errors are reported with exact condition-message formats per the story acceptance criteria. Validation is fail-fast across multiple vCenters; missing privileges are sorted for deterministic output. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
…aceful fallback (story openshift#38) Adds resolveVSphereCredentials() routing CredentialsRequest CRs annotated with cloudcredential.openshift.io/vsphere-component to per-component kube-system secrets. Falls back to shared credential with warning when component secret is absent or empty. Validates privileges via Story openshift#37 ValidateComponentPrivileges before provisioning. Supports multi-vCenter clusters with FQDN-keyed secret entries. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

Done — privilege_validation.go deleted in commit a3bcc3f. The entire privilege validation module has been removed along with privilege_validation_test.go. The resolveVSphereCredentials function no longer calls ValidateComponentPrivileges.

Missing hard validation for multi-vCenter credential completeness.
At Line 59, any non-empty component secret is accepted. That allows partial credentials (for example only one vCenter, or missing .password) to pass, which breaks the expected “error on missing vCenter entry” behavior.
Proposed direction
