John,

Do you consider this a total fix?  I tested this out and it does work as
long as excas is run on the same node that you do the ca_test from.  I
set up to test this and if I run both of these on the same machine I get
good results.  If I run ca_test (or some other ca utility) on another
machine, I get a message that fred was not found.  This seems similar to
the problem that I had when looking over this with Jeff Hill.  I even
think that this may have been the same variable that we set to get it to
work through localhost.

John
