SNMPv3 informs

[Buchan, Mike]

Thank you for your quick response.  I thought you had pointed out my error
in my first read through.  We were not using one of the
UsmUserTable::addNewRow forms which included the engine ID.  
For a test case, I altered the atm_mib example to do an SNMPv3 inform
following the steps you outlined in your reply.  I tried both forms of
UsmUserTable::addNewRow which include the engine ID as a parameter.  I am
still failing.  
As stated in a previous message I am using the SilverCreek tool to test the
interfaces.  In this case, I'm using there Notification Manager and looking
at the log entries.  The inform never makes it to the Notification Manger.
When in detailed mode, the log shows a set of 68 octets received and
indicates that it returns an UnknownEngineID report.  I am having no luck
deciphering the octets received in relation to what I think should be sent.
Just for information, the octets dump follows:

  30 82 00 40 02 01 03 30 82 00 0f 02 03 31 00 00 02 02 10 00
  04 01 04 02 01 03 04 12 30 82 00 0e 04 00 02 01 00 02 01 00
  04 00 04 00 04 00 30 82 00 12 04 00 04 00 a6 0c 02 02 11 36
  02 01 00 02 01 00 30 00

The following is a sniplet of the altered atm_mib.cpp.  I have only included
the parts pertinent to the v3 inform.  I don't understand what I'm missing.
I would appreciate if you could take a minute to scan through it and tell me
what I'm missing.  I'm certain It's going to be something simple and I'm
going to feel like an idiot but I'm stuck.

Thanks,
Mike Buchan

PS I think it was another Mike working on this project that you may have
talked to last year.  I had never worked with SNMP before November 2002.
