Sudo 1.6.3p5 and expect 5.32.1

Wed Nov 1 08:53:00 EST 2000

Hi all,

I am having trouble getting the included expect script to work on various
dec-unix machines versions 4.0f and 5.0a. It simply remains dead once
started. Also included is the trace output using alpha-trace (www.tru64.org)
I'm using Sudo version 1.6.3p5 and expect version 5.32.1.

Any help is much appreciated.
