Administrative Access
  For admin access, make sure that when using kubectl or trying to
  access the Veeam Kasten dashboard with
  Token Authentication you
  authenticate with a user that has a ClusterRoleBinding to the predefined
  k10-admin role.
Limited Access
  Non-admin users may be granted limited permissions to Veeam Kasten.
  Read-only access to the dashboard config is granted by creating a
  ClusterRoleBinding between the user and the predefined k10-config-view
  role. In addition, users may be granted operational access to their
  applications by creating a RoleBinding to the k10-basic role in their
  application's namespace.
Additional RBAC Access
Veeam Kasten now supports a more flexible permissions model which allows scoping of user permissions to perform Veeam Kasten actions only within the context of specified applications.
