```

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:
