[plt-scheme] Password validation in the web-server on Windows

Hi all,

Given a Windows username and a password, is there a simple
way for a servlet (or another program) to determine whether
the password is correct?

My plan is to run the PLT web-server on a machine, which
is member of a Windows domain. I hope it is possible
to avoid maintaining passwords on the web-server.
