# RADIUS Auth Method (API)

This is the API documentation for the Vault RADIUS auth method. For
general information about the usage and operation of the RADIUS method, please
see the [Vault RADIUS method documentation](/docs/auth/radius.html).

This documentation assumes the RADIUS method is mounted at the `/auth/radius`
path in Vault. Since it is possible to enable auth methods at any location,
please update your API calls accordingly.

## Configure RADIUS

Configures the connection parameters and shared secret used to communicate with
RADIUS.

| Method   | Path                         | Produces               |
| :------- | :--------------------------- | :--------------------- |
| `POST`   | `/auth/radius/config`        | `204 (empty body)`     |

### Parameters

- `host` `(string: <required>)` - The RADIUS server to connect to. Examples:
  `radius.myorg.com`, `127.0.0.1`
- `port` `(integer: 1812)` - The UDP port where the RADIUS server is listening
   on. Defaults is 1812.
- `secret` `(string: <required>)` - The RADIUS shared secret.
- `unregistered_user_policies` `(string: "")` - A comma-separated list of
  policies to be granted to unregistered users.
