Non-root user executing pon

[R. D. Loga]

When a non-root user types pon at the prompt they get "Connect script
failed".  Pon works fine for the root user.  I changed several file
permissions to get this far.  Do I have to change permissions on all the
scripts in /etc/ppp/ip-up.d directory too?  Is there an easy way to allow
non-root users to use pon?
