Scenario
Cedar Ridge Outfitters runs a small HQ in Denver and a warehouse in Boise.
Both sites now have their own remote-access server, and each one keeps a separate local
account list — so a field technician's password has to be reset in two places, and there is
no single record of who logged in where. You're the network engineer. Stand up
AUTH-HUB-01 as a central RADIUS server so both remote-access servers authenticate
field techs against one directory and report accounting to one place.
On each remote-access server, point authentication and accounting at AUTH-HUB-01, using the same shared secret you set in section 2.
