snmptrapd can't log V3 traps

  Thanks to Joan's help, I was able to configure a V3 trap destination
on my v5.4.1 agent.

  v5.5 snmptrapd successfully logs V2C traps from this agent, but I
can't get it to log V3 traps from the same agent.

  To simplify the issue, at present I am not trying to use V3
authentication or encryption (noAuthNoPriv).

  Here is most of my snmpd.conf:

[start snmpd.conf]

trapcommunity public
createUser _internal MD5 <neveryoumind>
rouser _internal
iquerySecName _internal
notificationEvent linkUpTrap linkUp ifIndex ifAdminStatus ifOperStatus
notificationEvent linkDownTrap linkDown ifIndex ifAdminStatus
ifOperStatus
monitor -r 5 -e linkUpTrap "Generate linkUp" ifOperStatus != 2
monitor -r 5 -e linkDownTrap "Generate linkDown" ifOperStatus == 2
authtrapenable 1
rocommunity "public"
rwcommunity "NewRWCommunity"

createUser trapuser1
trapsess -l noauth -u trapuser1 192.168.1.129

[end snmpd.conf]

  And here is my corresponding snmptrapd.conf on host 192.168.1.129:

[start snmptrapd.conf]

format1 "%02.2H:%02.2J:%02.2K TRAP%w.%q from %b Enterprise %n Security
%P Varbinds %v\n"
format2 "%02.2H:%02.2J:%02.2K TRAP%w.%q from %b Enterprise %n Security
%P Varbinds %v\n"

donotfork  yes

logOption f C:/Tools/net-snmp/usr/log/snmptrapd.log

disableAuthorization no

createUser trapuser1
authUser log trapuser1 noauth

[end snmptrapd.conf]

  This results in... nothing showing up in the log file except for the
startup banner.

  I have confirmed that the agent sends something to snmptrapd, because
when I comment out the createUser & authUser lines in snmptrapd.conf,
delete the persistent version of snmptrapd.conf, and restart snmptrapd,
every time the agent sends a trap this shows up in the log:

No access configuration - dropping trap.

  Can anybody detect what I'm doing wrong?  Version problem between 5.5
listener and 5.4.1 agent?  OpenSSL issue even with no authorization?

  Thanks,

  Ron
