you mean, have apache use sudo to change a user's email (sasl)
password? the purpose of this gizmo is to have the web server
set up to allow users to change their own passwords via a web
interface.
but it's not working -- not from apache, and not from the
command line. the "setuid" function is being ignored for some
reason. any ideas?

Wondering if you could change the bindings of CTRL+ALT+DEL, so
that it did a shutdown instead of a reboot? Sure! As root,
edit /etc/inittab. The line to edit looks like this:
ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
Just change "-r" to "-h".
