The OpenEdge Hive

I am looking for code which can set ntfs file-security on a file.

The application will work as follows,
- user requests a file
- an appserver which is running under a admin-account copies the file from a secure-folder to a shared folder.
- the appserver grants the user rights to the file, so he can access/delete it.

So how to grant the permission to the copied file?
