Passing credentials through to exec command

How can I pass user credentials (using integrated Windows authentication with IIS) through to a command which is being executed via exec()?  I am trying to write a simple web-based script which will sync files from our development server to production using robocopy.  The problem is that when I execute robocopy through exec(), it runs under the IIS user who doesn't have permissions to the production share.

I want the robocopy command to be executed under the credentials of whoever is logged in.  I have tried using runas and CPAU but neither worked (runas doesn't allow passwords to be passed in, and CPAU opens the command in another window so no output back to the php script).  Also, I do not want to modify permissions, or create any new users to accomplish.  The users who are logging in having the necessary permissions.

I appreciate any help.

I don't think that's possible with how IIS does things.  You'll probably need to find another solution.  Does this absolutely have to work inside of PHP?

I would like it to work in PHP, but any other language would be acceptible as long as it stays web-based.

Web-based would be the problem.  The way that IIS is structured doesn't really allow for that kind of access.  Apache allows for a highler level of control over this sort of thing, but also falls a bit short.  The big reason behind this, of course, being security issues and concerns.  There might be some special way of doing it, but not that I'm aware of.  I would create a domain user for your IIS account and grant that user the necessary privileges to access the resources you need.
