Does not work with hapi-auth-jwt2
If I add to my working code the npm module hapi-auth-jwt2, then all calls to /connect/provider returns 401.
How I added it:
as plugin in hapi _require('hapi-auth-jwt2')_
with a configuration 

```
    server.auth.strategy('jwt', 'jwt', {
      key: config.JWT.SERIAL,
      validateFunc: jwt.validate,
      verifyOptions: {
        algorithms: [ config.JWT.ALGORITHM ],
        ignoreExpiration: true
      },
      headerKey: config.JWT.HEADER
    });

    server.auth.default('jwt');
```

Then the routes for grant have the configuration for disable jwt:

```
    config: {
      auth: false
    }
```

It returns the body
`{"statusCode":401,"error":"Unauthorized","message":"Missing authentication"}`
and the headers

```
HTTP/1.1 401 Unauthorized
WWW-Authenticate: Token
content-type: application/json; charset=utf-8
cache-control: no-cache
vary: accept-encoding
content-encoding: gzip
Date: Wed, 26 Oct 2016 08:30:58 GMT
Connection: keep-alive
Transfer-Encoding: chunked
```

Do you have an idea why this is happening and could it be resolved by me or you?
