Other than doing a form fill on the User Application Portal 3.5 from a third
party reverse proxy (IBM WSebSEAL) is there a way that I can pass header
data to the User App to authenticate?

I am trying to do a form fill right now but it is not working and is messy,
I know that iChain does not pass form fill data to the portal, what header
data is it using to negotiate authentication?

Thanks for the information,
