Jim,
I really liked your 'presence of mind' in putting dilear1 with just hostname
for authentication and the dialer2 with a specific name in
your example - Great.
This combo is a good example to understand the auth... I took a long
time in getting - where to put which username?? etc.,
Thanks,
Ramesh.
