+
+          When you enable or disable an authenticator via this
+          endpoint, the status of the authenticator is stored
+          in the Conjur database. The enablement status of the authenticator
+          service may be overridden by setting the `CONJUR_AUTHENTICATORS`
+          environment variable on the Conjur server; in the case where this
+          environment variable is set, the database record of whether the
+          authenticator service is enabled will be ignored.

+          authenticators via the API, and is currently available at the Community
+          (or early alpha) level. This endpoint is still subject to breaking
+          changes in the future.**
