Thank you both for your help.  I don't know why I didn't think of that
before.  I had the expect mindset, and was determined to get it working
that way.

I added an entry for sudo for the script and it works without a hitch.
I'm still curious to know what was going on to disallow the
authentication in pexpect.  I had added 'www' to user 'admin', and
could su to root from the command line, so I don't think that was it.
Maybe it was a timing error, ie pexpect fired off the password too soon
or too late, or something in the apache environment that just
disallowed becoming root for security reasons.

Problem solved.
