help needed on net-snmp's snmptrapd issue

Hi all,
currently I am setting up a snmp trap server to do some testing on the snmp trap sending from our devices..

Snmp trap message can be received with Cd option , but it seems snmptrapd didn’t process this message. And I got such errors with CD. is there anything wrong or missed ? thanks a lot

dumph_recv:         ScopedPDU
trace: _snmp_parse(): snmp_api.c, 4159:
snmp_parse: Parsed SNMPv3 message (secName:pasitaes_inform, secLevel:authPriv): USM unknown security name (no such user exists)
trace: _sess_process_packet(): snmp_api.c, 5244:
sess_process_packet: received message id#1972796632 reqid#0 len 945
trace: _sess_process_packet(): snmp_api.c, 5247:
sess_process_packet: parse fail


Here are the configuation files below
