asp.net custom role provider not working in sandbox

Question

Hi all.

We've build a custom role provider and it was working fine locally, running Cassini. However, once we put our code in our sandbox environment, it stopped working. We've put debug statement in the custom role provider's code and it seems like that the custom code is not even getting execute. All the web.config is still the same as the one in local.

Any hints?

Thanks.
