# rsauth2-proxy: forward-auth for services that have no OIDC of their own.
# Needs, besides this file:
#   - Secret auth-proxy-creds (AUTH_PROXY_CLIENT_ID, AUTH_PROXY_CLIENT_SECRET,
#     AUTH_PROXY_COOKIE_SECRET); the client secret is the one of the Keycloak
#     client "rsauth2-proxy". Created by hand until Vaultwarden is the source.
#   - ConfigMap auth-proxy-routes, managed by Terraform (terraform/keycloak).
