Longhorn has no users of its own; nginx guarded it with basic auth using apr1 hashes, which Envoy Gateway does not support. An Envoy Gateway SecurityPolicy now sends visitors through an authentik OIDC application that only admins may use. The client secret lives in Vault at kv/longhorn-oidc and reaches both authentik and Envoy through External Secrets.
ESO 0.16.2 is the one release that serves both v1beta1 and v1. 0.17
stops serving v1beta1, so manifests still on v1beta1 would fail to sync
from the next hop on. For these resources the schemas are name-identical
(conversion strategy None); only the apiVersion changes.
