+# Configuring a service account when the cluster uses the `OwnerReferencesPermissionEnforcement` admission plugin
+
+The [`OwnerReferencesPermissionEnforcement`](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#ownerreferencespermissionenforcement) admission plugin requires a user to have permission to set finalizers on owner objects when creating or updating an object to contain an `ownerReference` with `blockOwnerDeletion: true`.
+
+When operator-controller installs or upgrades a `ClusterExtension`, it sets an `ownerReference` on each object with `blockOwnerDeletion: true`. Therefore serviceaccounts configured in `.spec.serviceAccount.name` must have the following permission in a bound `ClusterRole`:
+
+   ```yaml
+   - apiGroups: ["olm.operatorframework.io"]
+     resources: ["clusterextensions/finalizers"]
+     verbs: ["update"]
+     resourceNames: ["<clusterExtensionName>"]
+   ```
