RBAC & Security
Working

system:authenticated
)?
A
Groups are auto-generated from the user's RoleBindings
B
Groups are defined as Group objects in the RBAC API
C
Groups are supplied by the authenticator (e.g., certificate O fields, OIDC claims), not stored as RBAC objects
D
Groups are listed inside each ClusterRole's
subjects
field
