SNMPv3 informs

[Buchan, Mike]

Last week I sent a message about having problems getting the engine ID
discovery to happen when trying to do informs and got a quick response which
sounded promising.  As it turned out we were using the
NotificationOriginator method to send the inform and were still having
problems.  I looked for an example to see where else we might be making a
mistake.  The only example that I could find related to
informs/notifications was the atm_mib example.  It sends an SNMPv1 trap.  I
tested that against SilverCreek and it worked just fine.  I also changed it
to send an SNMPv2c trap which also worked just fine.  In both of these
cases, authentication was not used (as expected and verified by using bogus
data in SilverCreek for expected authentication request from the agent).  

Is there an example somewhere where an SNMPv3 inform works so I can compare
the setup and see what I'm missing or doing wrong?  I don't see it.  I think
I'm setting up all of the appropriate table and using the correct method
from NotificationOriginator.

Thank you in advance for your help.
