@ -246,6 +246,17 @@ Each time a user needs to be authenticated, the specified URL will be requested
If the URL returns a status code that begins with `20` (i.e. `200`), authentication is successful, otherwise it fails.
Please be aware that it's perfectly normal for the authentication server to receive requests with empty users and passwords, i.e.:
```json
{
"user": "",
"password": "",
}
```
This happens because a RTSP client doesn't provide credentials until it is asked to. In order to receive the credentials, the authentication server must reply with status code `401` - the client will then send credentials.
