# 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.

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                  |
| ------ | --------------------- |
| `POST` | `/auth/radius/config` |

#### 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.
