The somewhat adjusted 500 error message came from an intermediary proxy.
pca-proxy.cgi responded with "HTTP/1.1 500 SOA missing" which the proxy
translated into "HTTP/1.0 500 Internal Server Error". Once i skipped the
proxy everything went smoothly. Seems as if our internal proxy doesn't
care that much about the informational message provided by the target
host ... o.O ... interesting.

Thanks for integrating this very useful proxy authentication feature!
