      Description

      A customer has reported a problem on Trapd when receiving SNMPv3 Informs. Upon restarting OpenNMS, Trap stops processing Informs, and the following error appears on the log:

      2020-01-10 07:49:26,171 DEBUG [DefaultUDPTransportMapping_0.0.0.0/162] o.s.m.MPv3: RFC 3412 ยง7.2.13.a - Security engine ID ***** does not match local engine ID ***** 

      On the source code, a random Engine ID is associated with each USM User defined in trapd-configuration.xml, which is the behavior when an explicit ID is not passed when creating the UsmUser object, and I believe this is the source of the problem.
