We have been tasked with adding MFA to our Citrix ADC/Gateway logins using Azure AD MFA. We are currently on Citrix ADC 13.0 with Standard Edition License which doesn’t allow us to utilize Citrix’s built in nFactor feature.
Azure MFA Server has been deprecated so that is no longer an option. We’ve looked at https://docs.citrix.com/en-us/advanced-concepts/implementation-guides/citrix-gateway-microsoft-azure.html, but the solution it proposes seems much more complicated than what we’re looking to implement.
From everything I've read, my understanding is that it would involve Azure AD Conditional Access, but not sure how to tie that to the Citrix ADC.
Anyone have experience with implementing MFA on Citrix ADC using Azure AD?
