"""
Custom SecurityName
+++++++++++++++++++
Send SNMP GET request using the following options:
* with SNMPv3, user 'usr-md5-none', securityName 'myuser'
MD5 authentication, no privacy
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* for an OID in text form
The securityName parameter can be thought as an alias to userName and
allows you to address a USM Table row just as userName does. However
securityName can be made human-readable, also it is not an index in
usmUserTable, thus duplicate securityName parameters are possible.
