I don't even know if this is possible but it was mentioned
that if possible the client would like to have this functionality.
All users have CAC (Common Access Cards) to log into their
computer, connect to the intranet, etc. The idea is that instead of
forcing the users to create yet another account with yet another
email address to validate using the CAC card. Their email address
is associated with the card when it is created... but is there code
or something out there where I can pull that information and
compare it to say a list in a database of authorized individuals?
I believe a CAC card is a smart card with certificates on the
card chip. It is used by the DOD as an ID card. I know that there
is a Java spec for a package to interact with smart cards, but it
is in draft and not a released version of Java yet (well, this was
a while ago and it may be released now).
My best guess is that you would have to write a Java program
to be run in CF.
