Re: Send bucket policy to OPA server

Hi Seena,

I think it would probably help if you could describe your use case here, and what role you want OPA to play in the interpretation of these bucket policies. In other words, what is it that your OPA policy is doing with these bucket policy documents that shouldn't be done within radosgw?

    I think we should not be introducing new special case behavior, nor
    sending policy documents to OPA, which from what we have heard and
    read, intends to make no use of them.
