The block is at the end of this article Setting up Load Balancing for the NPS Servers The code block allows for group based decisions to selectively control MFA requirements at the ADC level. Update 24.04.22 - Additional Logic and Code by Wee Sern Soo. This configuration is based on a NetScaler Enterprise Licence, if you do not have Enterprise you will need to configure traditional Authentication Policies. I include the NSIP of each NetScaler, and the SNIP Because I am load balancing the NPS servers via NetScaler, the NPS Servers need to include the relevant NetScaler SNIP as a RADIUS Client.My configuration includes multiple NPS Servers for redundancy.I suggest starting with his article as the only point of change here, is once we get to the NetScaler configurations with a few exceptions noted below: I am not going to reinvent the wheel his work is always exceptional so that’s the starting point for NPS. Setting up Azure MFA, NPS roles and extensionsįirstly, Christiaan Brinkhoff has a fantastic article here which I base my initial configurations on. 1 x Access Gateway vServer (Unified Gateway).2 x NetScaler VPX Appliances with Enterprise Licencing.2 x NPS Servers with the Azure MFA Extensions.My setup for this guide consists of the following components: In this post, I am going to configure NetScaler nFactor Authentication to simplify the on-boarding of Azure MFA Authentication via the NPS Extensions with load balanced RADIUS Servers. The addition of the Azure NPS extensions into the product set simplifies the implementation and discussions yet again, as we can now leverage existing servers to provide the RADIUS endpoints for services such as NetScaler to authenticate against. It also occurs with all browsers.Azure MFA (Multi Factor Authentication) is fast becoming a topic being discussed with pretty much all my customers, even those that have an existing MFA solution in place, but are realising they may already be entitled to the offering from Microsoft as part of their +Security bundles within the Office 365 space.

I have compared the exports of cat bug on a successful and an unsuccessful login: The exports are identical! The problem only occurs with browsers - logins with the Workspace app always work. It is the login web page of the gateway - not the one of the storefront. Often after successful login, the login page is displayed again.
We only use one gateway with nFactor authentication. The configuration is clean and not complicated. I have also imported a second, new appliance. The problem occurs since the update from 12.1_55.18.
