To ensure that changes in the LDAP directory are reflected in object storage access changes, MinIO performs an **Automatic LDAP sync**. MinIO periodically queries the LDAP service to:

// error while parsing and validating.

	// Copy request.
	req := *r

	// Save authorization header.
	v4Auth := req.Header.Get(xhttp.Authorization)

	// Parse signature version '4' header.

)

// validateAdminReq will validate request against and return whether it is allowed.
// If any of the supplied actions are allowed it will be successful.
// If nil ObjectLayer is returned, the operation is not permitted.
// When nil ObjectLayer has been returned an error has always been sent to w.
func validateAdminReq(ctx context.Context, w http.ResponseWriter, r *http.Request, actions ...policy.AdminAction) (ObjectLayer, auth.Credentials) {

Handles GZip responses for any request that includes `"gzip"` in the `Accept-Encoding` header.

The middleware will handle both standard and streaming responses.
