If the web server and the DB server are the same machine or the web server
machine runs an identd service that you can trust, then you can do what you
want using ident authentication. The ident map file doesn't have an "all"
keyword, so you will need to update it as you add users.

VMS' set priv feature wasn't well designed (at least in early versions of VMS).
You didn't need to reauthenticate to elevate your privileges, so you still
had to be VERY careful when running other people's programs as they would
have access to your elevated privileges.
