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:

	ctx = withUnexpiredValuesPreserved(ctx)

	// Lookup before expiry.
	if g, w := ctx.Value(key), value; g != w {
		t.Errorf("Lookup before expiry: Got %v Want %v", g, w)
	}

	// Cancel the context.
	cancel()

	// Lookup after expiry should return nil
	if g := ctx.Value(key); g != nil {
		t.Errorf("Lookup after expiry: Got %v want nil", g)
	}
}

		if got := obj.IsAlias(); got != want {
			t.Errorf("%v: got IsAlias = %v; want %v", obj, got, want)
		}
	}

	// predeclared types
	check(Unsafe.Scope().Lookup("Pointer").(*TypeName), false)
	for _, name := range Universe.Names() {
		if obj, _ := Universe.Lookup(name).(*TypeName); obj != nil {
			check(obj, name == "any" || name == "byte" || name == "rune")
		}
	}

	// various other types
	pkg := NewPackage("p", "p")

		if got := obj.IsAlias(); got != want {
			t.Errorf("%v: got IsAlias = %v; want %v", obj, got, want)
		}
	}

	check(Unsafe.Scope().Lookup("Pointer").(*TypeName), false)
	for _, name := range Universe.Names() {
