Description Disco Vince Giffin 2009-09-24 15:59:40 MDT

An issue was reported where the following started failing once we upgraded sudo (to 1.7.0):
echo -n password | sudo -S id

The fix here is pretty easy (don't use the "-n" with echo).  Finding the root cause was a little bit trickier.  It would be nice if the manpage mentioned that a newline is required when using the stdin (-S) option.

I have added a sentence to that effect to the manual page.
