Update authelia stack: 4 auth cases, full Caddyfile, improved docs

Browse Source 
Keeps this as a standalone authelia+fail2ban stack (no Frigate services).

Changes:
- docker-compose.yml: fail2ban depends_on authelia with service_healthy
  condition so authelia.log exists before fail2ban tries to bind-mount it;
  add inline note about pre-creating the log file
- authelia/configuration.yml: expand access_control comment block to cover
  all 4 cases (added Case 3: app keeps own auth + Authelia as 2FA gate,
  and Case 4: app handles auth alone); clearer per-case commented rules
- caddy/Caddyfile (replaces snippet.example.caddyfile): complete Caddyfile
  with all 4 auth-case examples; (accesslog) imported in every block so
  fail2ban caddy-4xx jail covers all subdomains, not just gated ones;
  full inline docs for enabling Frigate proxy auth
- README.md: expand "Which sites" from 3 to 4 cases; add proxy-auth service
  compatibility table (Frigate, Grafana, Gitea, Nextcloud, HA, Portainer
  etc.); clarify fail2ban covers all sites via single caddy-4xx jail;
  add touch authelia/authelia.log to first-run; add troubleshooting entries
  for authelia.log bind-mount directory bug and fail2ban chain verification

## Which sites go behind Authelia?
There are four ways a site can relate to Authelia. Pick one per site.
| Case | App has built-in auth? | Supports proxy auth? | What to do |
|------|------------------------|----------------------|------------|
| **1** | No | n/a | `import authelia` in Caddy + rule in Authelia. Authelia is the only login. |
| **2** | Yes | Yes | `import authelia` in Caddy + rule in Authelia + disable app's own login form. Single login. |
| **3** | Yes | No | `import authelia` in Caddy + rule in Authelia. App auth is unchanged. User logs into Authelia then the app. Two logins. |
| **4** | Yes | — | Plain `reverse_proxy`. No `import authelia`, no rule. App handles auth. |
Concretely:
- **`doorbell.example.com`** (Pi PTT page) -- **case 1**. No app auth at all.
Authelia is the only gate. Use `two_factor` -- this URL controls a speaker.
- **`cam.example.com`** (Frigate UI) -- **case 2**. Frigate 0.14+ supports
proxy auth. Disable Frigate's login form and let Authelia drive both the
access gate and the role mapping (admin vs. viewer) via headers.
- **Router admin / NAS UI** -- **case 3** if you want a 2FA gate in front,
**case 4** if you just leave it to the app.
Default policy in `configuration.yml` is `deny`, so a domain with no rule
AND no `import authelia` in Caddy never reaches Authelia at all.
### How to tell if an app supports proxy auth (case 2)
Look for any of these in the app's docs:
- "Remote-User header", "trusted upstream", "trusted proxies"
- "Header-based authentication", "SSO via reverse proxy"
- Support for `X-Forwarded-User`, `X-Remote-User`, or `Remote-User`
| App | Proxy auth? | Notes |
|-----|-------------|-------|
| Frigate 0.14+ | Yes | `auth.enabled: False` + `proxy:` block in config.yml |
| Grafana | Yes | `[auth.proxy]` section in grafana.ini |
| Gitea / Forgejo | Yes | `REVERSE_PROXY_AUTHENTICATION_USER` in app.ini |
| Nextcloud | Yes | `TRUSTED_PROXIES` env + `overwriteprotocol = https` |
| Home Assistant | Yes | `trusted_networks` auth provider + `use_x_forwarded_for` |
| Jellyfin | Partial | Community plugin required |
| Portainer | No | Use Authelia OIDC integration instead |
| Vaultwarden | No | Use Authelia OIDC integration instead |
| Router/NAS admin | Rarely | Use case 3 (2FA gate) or case 4 |

## Which sites go behind Authelia?
Authelia is opt-in per site. The goal is one login (Authelia, with 2FA)
across everything that *can* use it -- and zero double-prompts for things
that already authenticate themselves and can't be retrofitted.
| Case | App has built-in auth? | Switchable to proxy auth? | What to do |
|------|-----------------------|---------------------------|------------|
| 1 | No | n/a | Gate with Authelia. Use `two_factor` for anything that controls hardware. |
| 2 | Yes | Yes (Authelia, Authentik, oauth2_proxy headers) | Disable the app's login form, point it at Authelia headers, gate with Authelia. Single login. |
| 3 | Yes | No | Don't involve Authelia. Plain `reverse_proxy` in Caddy. The app handles its own login. |
Concretely, in this household:
- **`doorbell.example.com`** (Pi PTT page) -- case 1. No app auth. Authelia
is the only gate. `two_factor`.
- **`cam.example.com`** (Frigate UI) -- case 2. Frigate 0.14+ supports
proxy auth, so disable Frigate's login form and let Authelia drive both
the auth and the role mapping. Single login covers Frigate too.
- **router admin / NAS UI / odd one-offs** -- case 3 territory. Plain
`reverse_proxy`, no `import authelia`, no Authelia rule.
Default policy in `configuration.yml` is `deny`, so a domain with no rule
*and* no `import authelia` in Caddy never reaches Authelia at all -- the
deny doesn't apply.

caddy reload --config /etc/caddy/Caddyfile subdomains automatically. Scanners spray everything, not just gated sites.
### Caddy access log path
fail2ban mounts `/var/log/caddy` from the host as read-only. Your Caddy
service must write to the same path. In your Caddy compose:
```yaml
services:
caddy:
volumes:
- /var/log/caddy:/var/log/caddy
``` ```
For each case-1 or case-2 domain, also add a rule under `access_control.rules` Create the directory before starting:

Confirm the Frigate UI now jumps straight to Authelia and back without both services:
a Frigate login screen.
If you want Authelia groups to drive Frigate roles (admin vs. viewer),
add a `role_map:` under `proxy:` (see Frigate docs).
### Caddy access log path
fail2ban mounts `/var/log/caddy` from the host as read-only. Your Caddy
compose needs to mount the same host path read-write so Caddy can write to
it. In your Caddy compose:
```yaml
services:
caddy:
volumes:
- /var/log/caddy:/var/log/caddy
```
Make sure the host directory exists and is writable by Caddy's UID:
```bash ```bash
sudo mkdir -p /var/log/caddy docker compose restart authelia
sudo chown -R 1000:1000 /var/log/caddy # adjust UID to match your Caddy docker compose restart frigate # in your Frigate stack
``` ```
Verify: `https://cam.example.com` in a private window goes to Authelia and
back without a Frigate login screen.

## fail2ban ## fail2ban
### Verify it's running and watching the right files fail2ban does **not** need its own separate stack or compose file. It lives
alongside Authelia in this same `docker-compose.yml`. It uses host networking
(no docker network needed) and watches two log sources:
| Jail | Log | Trigger | Ban |
|------|-----|---------|-----|
| `authelia` | `./authelia/authelia.log` | 3 failed logins in 10 min | 1 hour |
| `caddy-4xx` | `/var/log/caddy/access.log` | 30 HTTP 4xx in 2 min | 30 min |
The **caddy-4xx jail covers every site** on your Caddyfile as long as each
block has `import accesslog`. You don't need per-site jails.
Defense in depth: Authelia's `regulation` block locks the *user account*
after 3 bad passwords. fail2ban bans the *source IP* independently.

## Troubleshooting
### Redirect loop between site and `auth.<domain>`
Cookie domain mismatch. The `domain` under `session.cookies[]` must be the
*root* domain (e.g. `example.com`), and every protected site must be a
subdomain of that root, served over HTTPS. Mixed `http://` and `https://`
won't work; the cookie is `Secure`.
### "Configuration: session: option 'domain' and option 'cookies' can't be specified at the same time"
Old-style `session.domain: ...` left over from pre-4.38 config. Remove it;
this repo's `configuration.yml` already uses the new `session.cookies[]`
form.
### "access denied" with no login prompt
Default policy is `deny`. Add a rule under `access_control.rules` for the
domain you're hitting and restart Authelia.
### Authelia container restarts forever
```bash
docker compose logs authelia | head -50
```
Most often: missing/empty secret files, bad YAML in `configuration.yml`,
or a `users_database.yml` with an invalid hash.
### Caddy can't resolve `authelia`
Caddy isn't on `caddy_net`. Add `networks: [caddy_net]` to your Caddy
service and `caddy_net: external: true` at the bottom of its compose,
then `docker compose up -d caddy`.
### fail2ban bans don't actually block
Almost always: fail2ban isn't writing to the right iptables chain. With
dockerized Caddy, you need `chain = DOCKER-USER` (already set in the
shipped jail files). Verify:
```bash
sudo iptables -L DOCKER-USER -n
```
You should see jump rules pointing at f2b-* chains.
### Authelia logs show nothing
`log.file_path` is `/config/authelia.log` (i.e. `./authelia/authelia.log`
on the host). If the file isn't appearing, Authelia probably isn't
writing logs because it failed to start -- check `docker compose logs
authelia`.

## What's next ## Troubleshooting
Once this is steady-state: ### Redirect loop between a site and `auth.example.com`
- Add OIDC clients in Authelia for apps that speak OIDC natively (Grafana, Cookie domain mismatch. The `domain:` under `session.cookies[]` must be the
Gitea, etc.) -- they'll do real SSO without forward-auth headers. bare root domain (`example.com`), and every protected site must be a subdomain
- Switch the filesystem notifier to SMTP (see above). of it served over HTTPS. Mixed HTTP/HTTPS won't work; the session cookie is
- Consider a backup job for `authelia/db.sqlite3` and `authelia/secrets/` `Secure`.
-- losing either is a recovery mess.
### "access denied" with no login prompt
`default_policy: deny` and no `access_control` rule for this domain. Add a
rule in `authelia/configuration.yml` and restart Authelia.
### Authelia container restarts forever
```bash
docker compose logs authelia | head -50
```
Most often: missing/empty secret files in `authelia/secrets/`, bad YAML in
`configuration.yml`, or an invalid argon2 hash in `users_database.yml`.
### Caddy can't resolve `authelia`
Caddy isn't on `caddy_net`. Add `networks: [caddy_net]` to your Caddy
service and `caddy_net: external: true` at the bottom of its compose, then:
```bash
docker compose up -d caddy
```
### fail2ban bans don't block traffic
fail2ban is writing to the wrong iptables chain. With dockerized Caddy you
need `chain = DOCKER-USER` (already set in the shipped jail files). Verify:
```bash
sudo iptables -L DOCKER-USER -n
# Should show f2b-* jump rules.
```
### fail2ban: authelia jail missing / "No such file" on authelia.log
Docker created a directory at `./authelia/authelia.log` instead of a file
because the file didn't exist when the container started:
```bash
docker compose down fail2ban
rm -rf authelia/authelia.log # remove the directory Docker created
touch authelia/authelia.log # create as an empty file
docker compose up -d fail2ban
```
### Frigate still shows its own login after switching to proxy auth
1. Confirm `auth.enabled: False` in `frigate_config/config.yml`.
2. Confirm `trusted_proxies` subnet matches your `caddy_net` subnet:
```bash
docker network inspect caddy_net | grep -A2 '"Config"'
```
3. Restart Frigate: `docker compose restart frigate` (in your Frigate stack).
