Configuring snmpv3 informs

Hi everyone!

I am trying to configure snmpv3 informs and I am a little bit confuse about
the overall process.

My snmptrapd daemon is configured using options: -Lf /var/log/snmptrapd.log
at command line and doNotLogTraps false in the snmptrapd.conf file. I
created the user in the /var/lib/net-snmp/snmptrapd.conf file specifying the
authPassword, privPassword and both associated protocols. I didn't specify
an engineID. Stopped, started, stopped, started and checked the user has
been created.

On the client, I configured in the snmpd.conf the following (I have other
definitions, but these are relevant to my problem):

agentSecName myUser
trapsess -v3 -Ci mySnmpTrapdserver
authtrapenable 1
linkUpDownNotifications yes
defaultMonitors yes

I have also the following in the snmp.conf

defVersion 3
defSecurityName myUser
defSecurityLevel authPriv
defAuthType MD5
defPrivType DES


Where myUser is the user created on the server in the
/var/lib/net-snmp/snmptrapd.conf file.

Now, I am able to send informs using the command snmpinform with all the
flags, however, when I am starting the snmpd on the client, I am having the
following messages in its log:

snmpd: send_trap: No securityName specified (Sub-id not found: iso ->
snmperrErrorFlag)
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
failed to run mteTrigger querysnmpd: send_trap: No securityName specified
NET-SNMP version 5.3.0.1

And if I am inducing a authenticationFailure, I am getting the following in
the log of the client:

Authentication failed for myUser
snmpd: send_trap: No securityName specified (plaintext scopedPDU header type
00: s/b 30)

and nothing in the server's log. I even added -u myUser in the trapsess
line, the No securityName message disappeared, however, no message has been
sent to the server.

What am I missing?
