FastCGI Authorizers with nginx

[iT0m]

According to the specification FastCGI supports responders, filters and
authorizers. Nginx surely supports responders. I'm not sure, if it
supports filters, but it definitely doesn't support authorizers. Is
there a architectural reason behind it, was it simply forgotten, or
wasn't it requested?
We are interested in this feature! Unfortunately we don't have any C
knowledge. FastCGI authorizers are necessary if you want to use nginx
together with shibboleth.
