I'm running Apache, and the user if *effectively* nobody. I've tried to
chmod 4555 the cgi program, with no success (same result).

I've tried a new code (copied from passwd for popper), that I run both as
cgi and as interactive program:

        setuid (0);
        create a channel on a pty device,
        fork,
        child  --> exec (adduser....)
        master --> printf (messages from child)

result: perl adduser procedure hangs after the first line (copyright of the
writer) with or without the chmod 4555 on the program.

An interactive program doing system (adduser...) instead works correctly.

It looks like adduser hangs if is not working on a terminal.
Any suggestion? I may send my development environment (as attachment .tar)
to who is interested at the question.
