MFA for Aruba ClearPass

Aruba ClearPass is the NAC and policy engine behind a lot of enterprise wireless and wired access. It does rich authorization, but layering phishing-resistant MFA across its services is extra work. Authnull integrates as an external authentication/RADIUS source ClearPass can call, so you add a factor without re-architecting policy. You register Authnull as an authentication source, reference it in the relevant service, and a factor is enforced on the access methods you select.
