SP ReverseProxy no attributes

[Nathan Hughes]

Since we have an abnormal situation, I've setup a shibboleth SP on a Windows box with Apache.  I had to do this since our hosting server is an IBM iSeries with Apache.  The root problem is that I receive no POST data passed on to my resource.  Here are the steps in my test environment:

Step 1: User visits protected resource
Step 2: Using a reverse proxy, user is proxied to my Windows machine's apache server.
Step 3: The protected resource attempt is intercepted and sent to testshib IdP
Step 4: The user authenticates, and the IdP responds with a SAML assertion POST to my SP
Step 5: Using reverse proxy again, the SP then proxies the user to the protected resource with a 'getpostdata' method waiting for the POST data, but there is nothing sent to the resource.

I've read a bit about the relayState, and trying to store the data in 'ss:mem' and 'cookie', but neither forward the data.
Also, I may be wrong, but Apache's ProxyPass and ProxyPassReverse should forward that data without having to use mod_headers.

What am I missing?
Thanks,

Nathan Hughes
