I am writing an app in Ruby on Rails that I want to use for
authenticating Google Apps users.
I am having difficulty decoding the SAMLRequest. My code looks like
this:
string = CGI::unescape(params[:SAMLRequest])
doc = Base64.decode64(string)
zstream = Zlib::Inflate.new
buf = zstream.inflate(string)
The data from the SAMLRequest looks like this:

I get this error: "Zlib::DataError: incorrect header check"
I have tried every combination of unescape, decode and inflate that I
can think of, but no joy.
I will really appreciate any help.
Thanks in anticipation,
Keith
