I've done a similar thing to you: authenticating users from a legacy ASP application to an ASP.NET site. What would help, is if you could provide a little more detail (sample code, perhaps) of the process you've setup to do this with users coming from the legacy app to the ASPX app.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
