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

When a user provides their LDAP credentials, MinIO runs a lookup query to find the user's Distinguished Name (DN). The search filter and base DN used in this lookup query are configured via the following variables:

     */
    NetbiosAddress[] getNodeStatus(NetbiosAddress nbtAddress) throws UnknownHostException;

    /**
     * Lookup addresses for the given <code>hostname</code>.
     *
     * @param hostname the hostname to resolve
     * @param possibleNTDomainOrWorkgroup if true, perform additional master browser lookup
     * @return found addresses
     * @throws UnknownHostException if the hostname cannot be resolved
     */

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