# Directory Management

The SSO Manager ships with a built-in **Directory & Inventory Management** feature. Instead of just managing bare LDAP groups for your homelab, the Directory allows you to map out your infrastructure graph and assign rich metadata to your services.

## Architecture

The Directory models your homelab infrastructure using a parent-child graph (e.g. `Site -> Host -> Service`).

There are three primary **Kinds** of resources you can define:
- **Site**: A physical location, datacenter, or root node (e.g., `us-east`). Sites do not require parents.
- **Host**: A physical machine, Proxmox node, virtual machine, or LXC container. A Host **must** have a parent Site or another Host.
- **Service (App)**: An application, web service. A Service **must** have a parent Host or another Service.
- **OAuth Integration**: An OAuth 2.0 / OpenID Connect client application. An OAuth integration **must** have a parent Service.

By defining this hierarchy, the SSO Manager builds a queryable graph of your infrastructure.

## Automatic LDAP Group Creation

When you create a new **Host** or **Service** in the Directory via the web UI (or API), the SSO Manager will automatically provision two LDAP groups in your directory to govern access to that resource:

1. `<slug>_access` (Member level access)
2. `<slug>_admin` (Owner level access)

For example, if you create a Service named "Emby" with the slug `app_emby`, the system will create the LDAP groups `app_emby_access` and `app_emby_admin`. You can then assign users to these groups, and they will immediately see the service populate on their "My Services" dashboard.

## Resource Metadata

Resources carry a flexible `metadata` JSON object that can store essential context for your applications. The UI natively supports the following metadata fields:

### Common Metadata
- **Sub Type**: Free-form text to categorize the resource (e.g., `proxmox_node`, `linux`, `lxc`, `web`).
- **IP Address**: The internal IP address of the resource.
- **MAC Address**: The hardware address of the primary interface.
- **Host / URI Address**: The FQDN or URL of the resource (e.g., `https://emby.home.arpa`).
- **Production Environment**: A boolean toggle indicating if the resource is in production.

### Host Metadata
- **VMID**: The hypervisor VM or Container ID (e.g. `101`).
- **OS**: The operating system name (e.g. `Ubuntu 22.04.3 LTS`).
- **Kernel**: The kernel version string (e.g. `5.15.0-100-generic`).

### Service Metadata
- **Internal Port**: The local port the service binds to (e.g. `8080`).
- **External Port**: The reverse-proxy or external port (defaults to Internal Port if left blank).
- **Public (No Auth)**: Indicates if the service is exposed publicly without authentication.
- **External Reachable**: Indicates if the service is accessible outside the VPN/local network.
- **Git Repo**: The source code repository for the service (e.g. `https://github.com/...`).
- **Install Path**: The filesystem path where the service is installed (e.g. `/opt/app`).
- **Systemd Service**: The systemd unit name for the service (e.g. `app.service`).

## Navigating the UI

The Directory Management interface provides a **Tree View** toggle that visually nests your resources, making it easy to comprehend your network topography at a glance. You can also filter, search, and sort your entire infrastructure inventory. From the tree view, you can click the green `+` icon next to any resource to instantly add a child resource beneath it.

## Slug conventions

Slugs are the stable identifiers automation keys off, so the tooling around the SSO Manager follows a shared convention:

- **Sites**: `site_<name>` — e.g. `site_local`, `site_us-east`
- **Hosts**: `host_<hostname>` — e.g. `host_pve1`, `host_web01`
- **Services/apps**: a plain slug or `app_<name>` — e.g. `sso-manager`, `app_emby`

The auto-created LDAP groups derive from the slug (`<slug>_access` / `<slug>_admin`), so keep slugs stable once access groups are in use.

## Automatic registration

You don't have to build the graph by hand — the theta42 tooling registers itself:

### The stack itself (theta-env)

[theta-env](https://github.com/theta42/theta-env)'s `./setup.sh` seeds the directory on every run with the stack it deploys:

- a **site** (name from `CFG_SITE_NAME` in `setup.env`, default `local` → slug `site_local`) marked as the current site
- the **host** the stack runs on (`host_<hostname>`), with IP, MAC address, OS, and kernel collected from the machine
- the **services** it composes — SSO Manager, Proxy (management UI), OpenLDAP Directory (the LDAPS endpoint Linux hosts and LDAP-native apps bind to), and OpenResty Edge (the 80/443 data plane) — each with its address, internal port, and git repo
- the proxy's auto-registered **OAuth client**, linked under its service

The seed is idempotent and non-destructive: a resource whose slug already exists is considered operator-owned — the seed only fills in metadata fields you haven't set, and never overwrites your values.

### Linux hosts (ldap-client)

The `ldap-client` join script enrolls a Debian/Ubuntu machine for LDAP login (SSSD/PAM), LDAP-backed `sudo`, and SSH keys from the directory — and, when given an SSO API token, registers the machine as a `host_<hostname>` resource with its IP, MAC, OS, and kernel, parented to the site named by its configured location.

## Consumers of the directory

The inventory graph isn't just documentation — other components read it to make decisions:

- **[Jump Host](https://theta42.github.io/jump-host/)** — an SSH jump host that resolves which downstream machines a user may reach from their LDAP groups × the directory's `host` resources (`GET /api/discovery/resources?group=<cn>`), then bridges them in. The `host_<hostname>` slugs and `host_<slug>_access` groups this directory creates are exactly what it keys off; a host's `metadata.ip` / `metadata.sshPort` tell it where to connect. So a machine registered here (by theta-env or ldap-client) becomes reachable through the jump host the moment a user is in its access group.

Planned consumers (end-user catalog, firewall/DNS generation) and the model/API gaps they need are tracked in [`directory_spec.md`](https://github.com/theta42/sso-manager-node/blob/master/directory_spec.md) §9.

## API

All of the above uses the same admin API the UI does (group `app_sso_directory_admin` or `app_sso_admin`):

- `GET/POST /api/directory-admin/resources`, `PUT/DELETE /api/directory-admin/resources/:id`
- `GET/POST/DELETE /api/directory-admin/edges` — parent/child links (`hosts`, `oauth` relations)
- `GET/POST/DELETE /api/directory-admin/groups` — resource ↔ LDAP group links
- Read-only graph views (any authenticated user): `GET /api/discovery/resources`, `/api/discovery/resources/:slug`, `/api/discovery/graph`, `/api/discovery/me`
