I currently have a Citrix NetScaler VPX 200 and I would like to enable 2 factor authentication. I'm new to setting up 2FA and any advice would greatly be appreciated.
The goal is to have the user sign into the Netscaler web portal and authenticate with their domain (LDAP) credentials. Upon successful login, the user is required to enter a passcode/one time password that they would receive from an SMS message or ideally a code using an authenticator app (Microsoft or Google authentication app for example.) Once the user enters the one time password, the user can access the VPN or ICA portal.
When researching what is evolved to enable this, it looks like a RADIUS server is required. I do have a Windows Server 2016 RADIUS server, but it doesn't seem to support what I'm looking for, unless Microsoft's terminology is different. I've opened a case with Citrix, but the only thing provide is links to setup RADIUS on the gateway, which I already found before opening the case.
Has anyone been able to accomplish this? Thank you for your time.
