The Tempo Operator in OpenShift Distributed Tracing creates a ServiceAccount, ClusterRole, and ClusterRoleBinding when a user deploys a TempoStack or TempoMonolithic instance. This design allows any user with full access to their namespace to retrieve the associated ServiceAccount token and utilize it to make privileged API calls to:

Validate bearer tokens using the TokenReview API.

Check user permissions using the SubjectAccessReview API.
