FWIW, mod_authnz_fcgi in trunk provides AAA over FastCGI.

In case it looks useful to you:

* You can build mod_authnz_fcgi from trunk with 2.4.7.
* This package includes the necessary bits to build with 2.4.6 or other
recent httpd 2.4.x:

Oh! Thank you for that info. I have been using the 2.4.6 tarball source 
only, I will go and look at trunk now.
