[AGENT++] snmp++ get v3 problem

[Don Radick]

Apologies in advance for what is surely a user error.
Environment:  Ubuntu 9.04, snmp++ v3.2.23

Finally testing Snmp V3 for my application.
Using the example router configurations and command line (net-snmp) from
Cisco Cookbook Ian Brown, Kevin Dooley "O-Reilly" 
pages 656 - 660
using consoleExamples snmpGet to test

First example for V3 and noAuthNoPriv works correctly with snmp++

Second example with authNoPriv works fine with net-snmp command line:
snmpget -v3 -u cking -l authNoPriv -a MD5 -A daytona19y 10.10.1.8
sysName.0

snmp++ command line:
./snmpGet 10.10.1.8 -v3  -sl2 -sncking -uadaytona19y -authPROTMD5

fails with this (partial) error:
SNMP++ Get to 10.10.1.8 SNMPV3 Retries=1 Timeout=1000ms
securityName= cking, securityLevel= 2, securityModel= 3

Sorry for bother - do I have an error with the parameters?
