## Why Jellyfin authenticates users against Authentik over LDAP (app-password binds). The `authentik-ldap` Service, Gateway, and TLSRoute already exist in the authentik base, but nothing backed the Service — no LDAP outpost was ever deployed. This adds the missing Deployment so in-cluster clients (Jellyfin) can bind. Deployed as a separate Deployment inside the existing `authentik` namespace rather than a new app/namespace: the authentik overlay is already wired into the `platform` ApplicationSet and the LDAP Service/Gateway/TLSRoute already live here, so this needs no new AppProject/ApplicationSet wiring and keeps the outpost next to the core it serves. ## How - `ldap-outpost-deployment.yaml`: 2-replica (stateless) Deployment, image `ghcr.io/goauthentik/ldap:2026.5.3` (canonical upstream name; matches the deployed authentik chart version; containerd mirrors route via artifactapi). Pod labels match the existing `authentik-ldap` Service selector. - `AUTHENTIK_HOST=https://identity.k8s.syd1.au.unkin.net`, `AUTHENTIK_INSECURE=false`. - Trusts the internal CA via the established combine-certs initContainer pattern (concatenates the base roots with the reflected `vault-ca-cert`) + `SSL_CERT_FILE`. - `AUTHENTIK_TOKEN` sourced from secret `authentik-ldap-outpost-token`. - Resources set; TCP probes on the LDAP port; reloader annotation for token + CA rotation. - `ldap-outpost-vaultstaticsecret.yaml`: VSS (reuses the namespace `default` VaultAuth) materialising the token from KV `kubernetes/namespace/authentik/default/outpost-token` (key `token`). - `ldap-service.yaml`: adds the plaintext `ldap` port 3389 alongside the existing `ldaps` 6636 (ClusterIP only, no public exposure — external reach is via the pre-existing internal Gateway/TLSRoute). - `ldap-outpost-vmpodscrape.yaml`: VMPodScrape for the outpost metrics endpoint (:9300). - No sync-wave annotations. ## Dependency — token seed (blocking) The outpost pods CrashLoop until the token exists. After merge, the Authentik LDAP outpost token must be seeded into Vault KV at `kv/kubernetes/namespace/authentik/default/outpost-token` with key `token`. This path is provided by the corresponding terraform-authentik PR; the value must match the outpost token authentik issues. ## Validation `kustomize build --enable-helm apps/overlays/au-syd1/authentik` + repo kubeconform: 38 resources, Valid: 38, Invalid: 0, Errors: 0.
