You definitely need to have the right engineID in use.  Make sure that
/var/net-snmp/APPNAME.conf is writable by your application so it can
save the engine ID.

But because the snmpd.conf file may have a different engineID (and
should) you can't copy the usmUser line from it to the abc-demo.conf
file and have it work unless you make the engineID the same (which you
shouldn't do).

Instead, stop the abc-demo, add this to your abc-demo.conf file, and
then start it again:

  createUser myuser MD5 abcd1234

Which will create the user with the abc-demo's engine ID.  You shouldn't
need to specify the engineID on the snmpwalk command line either,
because it'll auto-detect it and synchronize with it.

[I'm refraining on discussing the security implementations of engineID
discovery here]
