+# Keycloak SSO Rollout (Server)
+
+## Compatible services to cover (assume up-to-date versions)
+- Gitea (OAuth2/OIDC)
+- Nextcloud (Social Login app)
+- Paperless-ngx (OIDC)
+- Mealie (OIDC v1+)
+- Jellyfin (OIDC plugin)
+- Kavita (OIDC-capable builds)
+- Readeck (OIDC-capable builds)
+- Audiobookshelf (OIDC-capable builds)
+- Matrix Synapse – intentionally excluded (see below) but natively OIDC if needed
+
+## Explicit exclusions (no SSO for now)
+- Syncplay
+- Matrix/Synapse
+- Arr stack (sonarr, radarr, lidarr, prowlarr, bazarr)
+- qbittorrent
+- sabnzbd
+- metube
+- multi-scrobbler
+- microbin
+- ryot
+- maloja
+- plex
+- atticd
+
+## Phased rollout plan
+1) Base identity
+   - Add Keycloak deployment/module and realm/client defaults.
+2) Gateway/proxy auth
+   - Add oauth2-proxy (Keycloak provider) + nginx auth_request for non-OIDC apps (e.g., homepage-dashboard, stash).
+3) Native OIDC wiring
+   - Configure native OIDC services (Gitea, Nextcloud, Paperless, Mealie, Jellyfin/Kavita/Readeck/Audiobookshelf) with Keycloak clients.
+4) Per-service rollout
+   - Enable per app in priority order; document client IDs/secrets and callback URLs.
+5) Verification
+   - Smoke-test login flows and cache any needed public keys/metadata.
