are you writing about the class UsmUserTable of agent++? The enties of
this table are localized users. Localization uses the engine id of the
agent and this id is built by default from the hostname.

No, SNMPv3 depends on the fact that each SNMP entity (any agent and any
manager,...) has its own _unique_ engine id.

If you added the users through the USM class using passwords, you can
save the users with passwords to a file through USM::save_users() and
load them using USM::load_users(). You can also use
USM::peek_first/next_user() to save the users yourself. If engine id
discovery is enabled, new localized users are created if needed.
