 ## [Unreleased]
 
+## [1.1.18] - 2026-07-21
+
+### Added
+- N-Way Multi-Master LDAP replication: `LDAP_SERVER_ID` + `LDAP_REPLICATION_HOSTS` configure `syncrepl` peers in the bundled OpenLDAP, and a new `/sites` page (nav: **Sites**) shows each configured peer's LDAP URL and live reachability.
+- A `location` property on users, editable from the profile and user-edit forms.
+
+### Fixed
+- `/sites` (added above) 500'd on every load: `views/sites.ejs` included nonexistent partials `header`/`footer` instead of this app's actual `top`/`bottom`. Fixed to match every other view.
+
+### Changed
+- Refreshed all README screenshots (dashboard, users, groups, OAuth apps) against the current UI, and added a new Sites & Replication screenshot.
+
+## [1.1.17] - 2026-07-18
+
+### Added
+- `conf.ldap.ldapsHost` and `conf.ldap.ldapsPort` config options (also settable via `app_ldap__ldapsHost` / `app_ldap__ldapsPort`). When `ldapsHost` is set, the `/integrations` page advertises that hostname for direct LDAPS binds instead of deriving it from the public OAuth issuer. This lets operators use an internal-only hostname (e.g. `ldap.internal.example.com` or `sso-manager` on the Docker network) and avoid port-forwarding 636 to the internet.
+- A contextual help panel on `/integrations` → LDAP explaining why LDAPS needs a hostname (not an IP), why 636 should not be publicly forwarded, and the recommended internal-DNS / Docker-internal alternatives.
+
+### Changed
+- `routes/index.js` now computes the displayed LDAPS URL from `conf.ldap.ldapsHost`/`ldapsPort` with fallback to the OAuth issuer host for backward compatibility.
+- `secrets.js.example`, `docs/configuration.md`, `docs/ldap.md`, and `DEPLOYMENT.md` document the new `ldapsHost`/`ldapsPort` options and recommended network layouts.
+- Bumped version to `1.1.17` in `nodejs/package.json`.
+
+## [1.1.16] - 2026-07-18
+
+### Security
+- Hardened LDAP filter and DN construction against injection. All user-supplied values interpolated into group filters (`models/group_ldap.js`) and RDN values used when adding users/groups (`models/user_ldap.js`) are now escaped before being sent to the LDAP server.
+- Replaced `Math.random()`-based token generation in `models/token.js`, `models/oauth_code.js`, and `models/oauth_client.js` with `crypto.randomUUID()` for session tokens, OAuth codes, access/refresh tokens, and client IDs.
+- Replaced `Math.random()`-based OTP generation in `OtpToken.issue()` with `crypto.randomInt()`.
+- `routes/oauth.js` now refuses to start if `oauth.jwtSecret` is missing or still set to the placeholder value, instead of falling back to a hardcoded public string.
+- Rendered docs and Terms-of-Service HTML in `routes/docs.js` and `routes/index.js` are now sanitized with `xss` to prevent stored XSS from malicious markdown.
+- Removed a `console.log` that wrote new-user data (including password hashes) to the log in `models/user_ldap.js`; reduced login-path error logging to `error.name`/`error.message` only.
+
+### Changed
+- Public-release packaging: removed `"private": true` from `nodejs/package.json` and bumped version to `1.1.16`.
+- CI workflow (`.github/workflows/pr-tests.yml`) now sets `app_oauth__jwtSecret` so the test suite can run against the new startup-time JWT validation.
+
+### Fixed
+- `models/email.js`: fixed a template bug where the rendered `from` address used `template.message` instead of `template.from`.
+
+## [1.1.15] - 2026-07-18
+
+### Changed
+- Rewrote `install.sh` as an idempotent git-clone installer, replacing the old flag-driven, copy-based one — `wget -O - .../install.sh | sudo bash` now works the same way it does for theta42/proxy. Installs to `/opt/theta42/sso-manager` (was `/opt/sso-manager`). First run only: bootstraps OpenLDAP with a generated admin password + JWT secret and seeds `/etc/sso-manager/secrets.js` (was `/opt/sso-manager/conf/secrets.js`, hand-filled from CLI flags); later runs never touch LDAP or the secrets file again. `ops/systemd/sso-manager.service` sets `CONF_SECRETS=/etc/sso-manager/secrets.js` to match.
+- `install.sh` now prints the version it's updating from/to (or "Already up to date") on every run.
+
+### Fixed
+- `install.sh` could hang indefinitely on a fresh host if a base package pulled in `tzdata` as a new dependency (no TTY for the interactive timezone prompt), or if the debconf `slapd/domain` value was malformed (a raw DN fragment instead of a dotted domain) — slapd's postinst hangs rather than failing cleanly on a bad domain. Both fixed.
+- `ops/ldap-setup.sh`'s ppolicy-overlay checks used an LDAP substring filter against an attribute that doesn't support substring matching, so they always reported the overlay as unconfigured even when it was correctly set up (stored as `{0}ppolicy`) — the final verification step always failed as a result. Fixed to filter on `(objectClass=olcOverlayConfig)` instead, matching every other check in that script.
+
+## [1.1.14] - 2026-07-17
+
+### Changed
+- Bumped `@simpleworkjs/conf` to 1.2.0 and `jq-repeat` to 2.2.0. The Docker entrypoint now sets the new `CONF_SECRETS` env var to point directly at a mounted `sso-secrets.js` instead of symlinking it into `/app/conf/secrets.js` — the app no longer needs write access to its own `conf/` directory to pick up mounted secrets.
+
+## [1.1.13] - 2026-07-17
+
+### Fixed
+- The new concept docs' cross-links (`concepts-accounts.html` etc.) are the correct, working URL on the Jekyll/GitHub Pages build (where the page's URL is its filename stem) but didn't resolve in the in-app docs viewer, which serves docs at a separate short slug (`/docs/accounts`). The in-app renderer now also resolves a doc's real filename as a fallback, so one link written in a doc works on both targets.
+
+## [1.1.12] - 2026-07-17
+
+### Added
+- Three new plain-language docs aimed at less technical readers, replacing the schema-level LDAP/OAuth/API docs as the target of most card help links: **Accounts, Groups & Managers**, **Connecting Apps (SSO)**, and **API Tokens**. Each links onward to the deeper technical reference for readers who want it; the technical docs link back the other way too. The personal-access-token card (previously missed) now links to its own doc.
+
+### Fixed
+- The in-app docs viewer rendered every `docs/*.md` page with a garbled heading and a stray horizontal rule at the top — Jekyll front matter (meant only for the GitHub Pages build) was never stripped before being handed to the markdown renderer. Also fixed: cross-doc links (`ldap.html`, `index.html`, etc.) never resolved in-app, since this viewer serves docs at `/docs/<slug>` with no `.html` suffix — they're now rewritten to the correct in-app URL, the same way image paths already were.
+
+## [1.1.11] - 2026-07-17
+
+### Changed
+- Moved the help (❓) link out of the global header and onto each relevant card individually (Invite User, Add new user, User List, Service Accounts, group cards, OAuth/LDAP integration cards, My groups, Members of `<uid>`'s group, New API Token) — each now deep-links straight to the doc that actually covers it, instead of one generic header icon.
+
+## [1.1.10] - 2026-07-17
+
+### Added
+- A help icon (❓) in the top-right header now deep-links to the doc most relevant to the current page (falls back to the docs index elsewhere).
+- The in-app docs viewer (`/docs`) is now searchable — a simple line-substring search over the same local doc set, no new dependency, still works with no internet access.
+
+## [1.1.9] - 2026-07-17
+
+### Added
+- Every account's personal Unix group (its primary GID holder) can now have supplementary members managed from the account's profile page ("Members of `<uid>`'s group", admin-only) — e.g. to share write access to files owned by that group. Uses the standard `memberUid` attribute (RFC 2307 `posixGroup`).

+
+# Accounts, Groups & Managers
+
+This page explains the concepts behind the Users and Groups pages in plain
+language. If you want the technical schema/attribute-level detail instead,
+see the [LDAP reference](ldap.html).
+
+## What's an account?
+
+Every person (or app) that can sign in through this SSO Manager has an
+**account** — a username, a display name, maybe an email address, and a
+password (or, for service accounts, no password at all — see below).
+Accounts live in the directory this app manages, and any other app you've
+connected (Gitea, Home Assistant, your Wi-Fi, whatever) checks against these
+same accounts instead of keeping its own separate list of users and
+passwords.
+
+## Two kinds of account: people and service accounts
+
+Most accounts belong to an actual person — check **Users → People** to see
+them. But sometimes you need an account for something that *isn't* a
+person: a media server, a backup script, a bind account another app uses to
+look people up. These are **service accounts**, listed separately under
+**Users → Service Accounts**, and they're different from a person's account
+in two ways that matter:
+
+- **No email required.** A service account doesn't need a mailbox, so the
+  form doesn't ask for one.
+- **A password is optional.** If you leave it blank, nobody can log in as
+  that account — which is exactly what you want for something that only
+  ever gets used programmatically (a script authenticating with an API
+  token, or another app binding with a fixed, separately-configured
+  password you set yourself). Only give it a password if the account
+  genuinely needs to log in or bind somewhere as itself.
+
+Aside from those two differences, a service account is a completely normal
+account under the hood — it can belong to groups, have a manager, and so
+on, just like anyone else's.
+
+## Groups: who can do what
+
+A **group** is just a named list of accounts, used to control access. This
+app has a handful of built-in groups that grant admin powers (e.g. only
+people in the `app_sso_admin` group can see the Users/Groups/Integrations
+pages at all), but you can also make your own groups for any app you
+connect — say, a group listing everyone who should be allowed into your
+photo server. Once a group exists, add or remove members from the
+**Groups** page, and point the other app's "who's allowed in" setting at
+that group's name.
+
+## Every account's personal group
+
+Separately from the groups above, every single account — person or
+service account — automatically gets its own small, personal group when
+it's created, named after the account itself. Most of the time you'll
+never think about this; it exists so that, on a Linux system connected to
+this directory, each account "owns" its own files by default the same way
+a normal Unix user account would.
+
+Occasionally you'll want to share that ownership with someone else — for
+example, letting a second account also have write access to files a
+service account owns. That's what the **"Members of `<uid>`'s group"**
+section on a profile page is for: add another account there, and the
+underlying Linux permissions treat them as if they belong to that same
+personal group too.
+
+## What's a "manager"?
+
+Every account has one or more **managers** — the people allowed to edit
+that account's profile (phone number, SSH key, home directory, and so on)
+without needing full admin rights. By default, whoever created an account
+(the admin who added it, or whoever sent the invite) becomes its first
+manager, but you can add or remove managers later from the account's Edit
+form.
+
+This is useful for service accounts especially: if a service account
+belongs to a particular project or person, make them its manager so they
+can maintain it — rotate its SSH key, adjust its description — without
+needing to be a full SSO administrator.
+
+## Inviting someone vs. adding them yourself
+
+From the Users page you can either fill in someone's details yourself
+("Add new user"), or send them an **invite** — an email (or a link you copy
+and send however you like) that lets them pick their own username and
+password. Either way, the resulting account is identical; invites are just
+a convenience so you don't have to know someone's preferred username or
+handle their password directly.
+
+## Want more detail?
+
+This page deliberately leaves out LDAP schema names, attribute types, and
+protocol-level detail. If you're connecting a third-party app directly to
+the LDAP directory, or you just want to know exactly what's stored where,
+see the [LDAP reference](ldap.html).

+
+# API Tokens
+
+This page explains what an API token is and when you'd want one. For the
+full list of API endpoints a token can call, see the
+[API reference](api.html).
+
+## What's an API token, in plain terms?
+
+Normally, you interact with this app by logging in through a web browser.
+An **API token** (also called a personal access token, or PAT) is an
+alternative way in — a long, random string that a script, a scheduled job,
+or another program can use instead of a username and password, to act on
+your behalf without a human typing a login in each time.
+
+If you've ever set up a script to talk to GitHub, GitLab, or a similar
+service using a "token" instead of your real password, this is the same
+idea.
+
+## When would you actually need one?
+
+Most people never need to create one of these — you'll only want a token
+if you're automating something, for example:
+
+- A script that syncs users or groups from somewhere else into this SSO
+  Manager on a schedule.
+- A backup or monitoring job that checks this app's health via its API.
+- A CI/CD pipeline that needs to register or update an OAuth client
+  automatically.
+
+If you're not doing any of that, you don't need an API token — just log in
+normally through the web UI.
+
+## How it works
+
+Create a token from your Profile page, give it a name so you remember what
+it's for later, and optionally an expiry. You'll be shown the token's
+value **exactly once** — copy it somewhere safe immediately, because it
+can't be viewed again afterward (only revoked or rotated). Whatever script
+or tool you're using it with sends it along with each request, the same
+way a browser sends your login session.
+
+A token acts **as you**, with **your** permissions — if you're not an
+admin, a token you create can't do admin-only things either. If you ever
+suspect a token has leaked (ended up somewhere it shouldn't have, like a
+public script or log file), revoke it immediately from your Profile page;
+it stops working right away.
+

+response examples — for that, see the full [API reference](api.html).

+title: Connecting Apps (Single Sign-On)
+description: A plain-language guide to OAuth/OIDC clients and single sign-on in SSO Manager.
+---
+
+# Connecting Apps (Single Sign-On)
+
+This page explains, in plain language, what happens when you "connect" an
+app to your SSO Manager so people can log into it with their existing
+account. For the technical endpoint/token detail, see the
+[OAuth reference](oauth.html).
+
+## What does "single sign-on" actually mean?
+
+Instead of every app you run having its own separate list of usernames and
+passwords, they all check with this SSO Manager instead. You log in once,
+here, and any connected app trusts that login — no separate password to
+remember or manage for each one. If you ever need to lock someone out
+everywhere at once, you do it in one place (deactivate their account here)
+instead of hunting down every app individually.
+
+The technology behind this is called **OAuth 2.0** and **OpenID Connect
+(OIDC)** — you'll see both names used, often together, referring to the
+same thing. You don't need to understand the protocol to use this page;
+what matters practically is the handful of concepts below.
+
+## What's a "client"?
+
+Every app you connect is registered here as a **client** — a single entry
+on the Integrations page representing that one app. Registering a client
+gives you a **Client ID** and **Client Secret**: think of these like a
+username and password, but for the *app itself* rather than for a person.
+You paste them into the other app's own "Single Sign-On" or "OIDC" setup
+screen, along with the discovery URL shown at the top of this page, and
+that app is now able to ask this SSO Manager to authenticate people on its
+behalf.
+
+**Treat the Client Secret like a password** — anyone who has it can
+impersonate that app when talking to your SSO Manager. If you ever suspect
+it's leaked, rotate it from the client's card.
+
+## What are "scopes"?
+
+**Scopes** control what information a connected app is allowed to ask for
+about the person logging in — their username, email, group memberships,
+and so on. Most apps tell you exactly which scopes they need in their own
+setup instructions; when in doubt, the default set (`openid`, `profile`,
+`email`, `groups`) covers what nearly every app expects.
+
+## "Restrict to Groups"
+
+By default, *any* account with an SSO Manager login can sign into a
+connected app. If that's not what you want — say, a home automation
+dashboard that only certain family members should reach — set **Restrict
+to Groups** on that client to one of your [groups](concepts-accounts.html).
+Only members of that group will be allowed to log into that particular
+app; everyone else gets turned away at the login step, even though their
+SSO Manager account still works everywhere else.
+
+## Redirect URIs
+
+A **Redirect URI** is the exact web address the connected app wants people
+sent back to once they've logged in here — it's a security measure so an
+attacker can't trick the login flow into redirecting somewhere else. The
+app's own setup instructions will tell you this value; copy it in exactly
+as given. If the app is reachable via more than one hostname (for example,
+because it sits behind [theta42/proxy](https://theta42.github.io/proxy/)),
+this field supports wildcard patterns — see the inline help under the
+field itself for the exact syntax.
+
+## Want more detail?
+
+This page intentionally skips the protocol-level detail (exact endpoint
+URLs, token formats, claim names). If you're troubleshooting a connection
+or building something against the API directly, see the
+[OAuth reference](oauth.html).

+## Choosing the LDAPS hostname
+
+The `/integrations` page advertises an **LDAPS URL** for direct LDAP binds. By
+default it derives that URL from the public OAuth issuer (e.g.
+`https://sso.example.com` → `ldaps://sso.example.com:636`). That is convenient,
+but it implies LDAP clients reach your directory through the same public
+hostname — which usually means port-forwarding 636 through your router.
+
+**Do not port-forward LDAPS (636) to the public internet.** LDAP simple binds
+have no rate limiting and are a brute-force target. Instead, use one of these
+internal-only patterns and set `conf.ldap.ldapsHost` (or
+`app_ldap__ldapsHost`) so the `/integrations` page shows the right URL.
+
+### 1. Same Docker / local network host (best for apps on this machine)
+
+If the LDAP client runs on the same Docker network as the SSO Manager (for
+example, the bundled `theta-env` stack), use the internal service name:
+
+```
+ldaps://sso-manager:636
+```
+
+In `conf/secrets.js`:
+
+```javascript
+ldap: {
+  ldapsHost: 'sso-manager',
+  ldapsPort: 636,
+}
+```
+
+The proxy in theta-env already uses this internally. The bundled slapd cert
+includes `sso-manager` in its SAN when `LDAP_CERT_CN` is left at its default,
+so hostname verification works without extra setup.
+
+### 2. LAN host behind your router (best for separate home-lan machines)
+
+Create an internal-only DNS record — e.g. `ldap.internal.example.com` →
+`192.168.1.10` — using your router, Pi-hole, or a local `hosts` file. Then get
+or generate a cert whose SAN/CN matches that internal name:
+
+- **Let's Encrypt wildcard** (`*.internal.example.com`) works if you own the
+  public domain and can complete DNS-01 challenge; the record itself can stay
+  private/routable only inside your LAN.
+- **Internal CA** is fine for a pure LAN: run a small CA, issue a cert for
+  `ldap.internal.example.com`, and distribute the CA cert to clients.
+- **Self-signed** with `LDAP_CERT_CN=ldap.internal.example.com` also works; copy
+  the generated `ldap.crt` to each client and trust it.
+
+In `conf/secrets.js`:
+
+```javascript
+ldap: {
+  ldapsHost: 'ldap.internal.example.com',
+  ldapsPort: 636,
+}
+```
+
+The URL on `/integrations` becomes `ldaps://ldap.internal.example.com:636`.
+
+### 3. Public hostname (acceptable only behind a VPN/firewall)
+
+If a remote host must bind LDAP, put it behind a VPN (Tailscale, WireGuard,
+etc.) or a tightly locked-down firewall rule. In that case the public hostname
+may be appropriate, but the LDAPS port should still not be reachable from the
+open internet.
+
+### Why not just use the LDAP server's IP address?
+
+TLS clients verify the server name against the certificate. Connecting to
+`ldaps://192.168.1.10:636` with a cert issued for `*.internal.example.com`
+will fail hostname verification unless you disable cert checks — which removes
+most of the security benefit of LDAPS. Always use a hostname that matches the
+cert.

+# Geo-Location Scaling (Replication)
+
+SSO Manager is built to be a self-contained identity provider, but if you have multiple physical sites, you may want a local copy of the directory at each site to ensure low latency and high availability.
+
+## Why and when to use this?
+- **High Availability (HA)**: If your primary site goes completely offline, your other sites can still authenticate users locally without depending on a WAN link.
+- **Low Latency**: Applications at a remote site can bind directly to their local LDAP server (`localhost` or LAN IP) instead of traversing the internet to query the primary site, making logins blazing fast.
+- **Independent Failure Domains**: By replicating only the LDAP directory (the source of truth) and keeping session state (Redis) independent, you prevent complex "split-brain" scenarios in the web UI. A failure at Site A won't bring down Site B.
+
+By default, the `sso-manager` Docker container runs a single, independent OpenLDAP instance. However, you can enable **N-Way Multi-Master Replication** via environment variables.
+
+## How it works
+
+In an N-Way Multi-Master setup, every site runs a fully active OpenLDAP server (`slapd`).
+- **Reads and Writes anywhere**: A user can change their password or update their profile at Site A, Site B, or Site C.
+- **Conflict Resolution**: OpenLDAP's `syncrepl` engine uses Context Sequence Numbers (CSN) to track changes. If Site A goes offline and a user changes their password at Site B, Site A will automatically pull the newest changes the moment it rejoins the cluster.
+- **Independent Redis**: Session data, API Tokens, and OAuth Clients are stored in Redis. By design, Redis is NOT replicated in this geographic setup. This ensures that a failure at Site A never causes Site B's Redis to become read-only, which would break the web UI at Site B. OAuth clients must be configured per-site.
+
+## Configuration
+
+To enable replication, you must pass two environment variables to the `sso-manager` container:
+
+1. `LDAP_SERVER_ID`: A unique integer for this node (e.g., `1`, `2`, `3`). This MUST be unique across the cluster.
+2. `LDAP_REPLICATION_HOSTS`: A space-separated list of the LDAP URLs of all **other** nodes in the cluster.
+
+### Example using `theta-env` / Docker Compose
+
+**Site 1 (`setup.env` or `docker-compose.yml`)**
+```env
+LDAP_SERVER_ID=1
+LDAP_REPLICATION_HOSTS="ldaps://sso.site2.com:636 ldaps://sso.site3.com:636"
+```
+
+**Site 2 (`setup.env` or `docker-compose.yml`)**
+```env
+LDAP_SERVER_ID=2
+LDAP_REPLICATION_HOSTS="ldaps://sso.site1.com:636 ldaps://sso.site3.com:636"
+```
+
+**Site 3 (`setup.env` or `docker-compose.yml`)**
+```env
+LDAP_SERVER_ID=3
+LDAP_REPLICATION_HOSTS="ldaps://sso.site1.com:636 ldaps://sso.site2.com:636"
+```
+
+Once configured, the container's entrypoint will automatically load the `syncprov` module, enable `mirrormode`, and generate the necessary `syncrepl` blocks in `/etc/openldap/slapd.conf`.
+
+## User Locations
+
+When creating or editing a user, you can specify their **Location (Site)**. This maps directly to the standard LDAP `l` (localityName) attribute, allowing you to track which physical site a user belongs to natively within the directory.
