@ -57,7 +57,7 @@ Items in the `dynamodb` table must have three attributes:
- `id` (string): The id is the primary key.
- `name`(string): The name is used as the name of the frontend or backend.
- `frontend` or `backend` (map): This attribute's structure matches exactly the structure of a Frontend or Backend type in traefik.
See `types/types.go` for details.
- `frontend` or `backend` (map): This attribute's structure matches exactly the structure of a Frontend or Backend type in traefik.
See `types/types.go` for details.
The presence or absence of this attribute determines its type.
So an item should never have both a `frontend` and a `backend` attribute.

### Authentication
- Basic Authentication
Passwords can be encoded in MD5, SHA1 and BCrypt: you can use `htpasswd` to generate those ones.
Users can be specified directly in the toml file, or indirectly by referencing an external file;
if both are provided, the two are merged, with external file contents having precedence.
```toml
# To enable basic auth on the webui with 2 user/pass: test:test and test2:test2
[web.auth.basic]

usersFile = "/path/to/.htpasswd"
```
- Digest Authentication
You can use `htdigest` to generate those ones.
Users can be specified directly in the toml file, or indirectly by referencing an external file;
if both are provided, the two are merged, with external file contents having precedence
```toml
# To enable digest auth on the webui with 2 user/realm/pass: test:traefik:test and test2:traefik:test2
[web.auth.digest]
users = ["test:traefik:a2688e031edb4be6a3797f3882655c05 ", "test2:traefik:518845800f9e2bfb1f1f740ec24f074e"]

## Metrics
You can enable Traefik to export internal metrics to different monitoring systems.

# Buckets=[0.1,0.3,1.2,5.0]
