Freeradius had good docs and examples. The Raritan KVMs did the basics well: IP address, shared secret via the web gui. Then create a Group with the perms for your users. The secret ingredient was adding the users group to radius. I did it in sites-available/default adding: update reply {&Filter-Id = "Raritan:G{Techs}"} in the post-auth section. Your needs/usage will vary. #freeradius #raritan
