[erlang-patches] SNMP bugfix to usmUserTable

Dear all,

usmUserTable suffers from the problem that it doesn't support creating
new users (by cloning them) and changing their passwords in the same

This is allowed by the MIB definition, and some SNMP test suites do
exactly that numerous times when they check the correctness of SNMPv3
support. SNMP managers might also make use of that feature.

The patch attached to this e-mail solves the issue and allows SNMPv3
user creation to succeed if all required information is passed to the
agent in a single SNMP set request.

Kind regards,

Dr. Stefan Zegenhagen
