If you set an empty lookup bind password, the lookup bind will use the unauthenticated authentication mechanism, as described in [RFC 4513 Section 5.1.2](https://tools.ietf.org/html/rfc4513#section-5.1.2).

### User lookup

	for _, kv := range kvs {
		if kv.Key == key {
			return kv, true

	}

// Lookup - lookup a key in a list of KVS
func (kvs KVS) Lookup(key string) (string, bool) {

		}
	}
	return "", false
}

// Config - MinIO server config structure.

- CoreDNS (for DNS management based on populated bucket DNS service records, optional)
