Hi pberna:
Impersonation is more difficult in forms authentication. If you use
the username and password attributes of the <identity> tag then yes,
you are passing the username and password for a windows account. Every
local resource ASP.NET touches will be done with the credentials
specified in the <identity> tag, for example, file access, service
control, connecting to a database with a trusted connection.
Is the web application soley for the purpose of controlling the
service? Is it exposed to the Internet?
