We have a security appliance we host which provides secure connection to remote servers and workstations. We would like to implement 2 factor authentication as one of our clients requires it. I contacted the security appliance support and they indicated that using a Radius server with 2 factory authentication enabled would meet this requirement.
Can I use a windows server for the radius server?
Does this need to be on one of our domain controllers?
Will this effect our internal user authentications?
Are there guides available for this setup?
