I know that I can use iChain to pass user credentials in to the User App to
automate a user authentication but can I use another reverse proxy
solution? I have a customer that wants to use IBM's TAM solution instead
of iChain but still wants to use eDir, IDM and the User App to manage
everything else.

What type of header is the User App willing to accept, or will I need form
fill, if it accepts headers what does it need to look like so I can
replicate this on TAM?

Thanks for any help...
