Networker Virtual Edition discovery into CMDB

Hi,

When using Networker VE, 9.2 or 18.x, with a CMDB that wants to use authenticated discovery, what is the best way to do that? I see that we can configure SMTP based notification, but that is not helpful when the CMDB wants to discover the appliance itself. Options given me by the CMDB team are we can use SSH with a dedicated user (Can I safely add a user to an appliance?) or SNMP, but I have not seen any guidance in the docs to enable and configure either. I am asking generically as this may be generic for many, but if it matters, we are talking about Service-Now MID. Thanks.
