+- **Plain LDAP (389) now reachable from the host** — `docker-compose.yml` published only LDAPS (636); plain LDAP (389) was deliberately not mapped, so the stack host's own enrollment (`setup.sh` → ldap-client, which configures sssd against `ldap://localhost:389` and `ldaps://localhost:636`) could not reach the directory over loopback. Both 389 and 636 are now published to the host (bind 0.0.0.0; `LDAP_BIND`/`LDAPS_BIND=127.0.0.1` to lock to the host only).

 Optional extra ports (only if you need them):

   SAN. The default shows the public SSO hostname, which implies a public route.
