>
> Currently {{SimpleDBProviderBackend}} doesn't retry the authorization properly. Problems are:
> # It retry count is hard coded. Always retries once
> # No wait time between before retries
> # The method calls itself recursively, which could causes stack overflow if retries too many times
> # If an exception happens in {{SentryPolicyServiceClient.listPrivilegesForProvider}}, then {{policyServiceClient}} won't be closed, which could cause resource leak.
