SAML Authentication between Citrix & Microsoft with Azure MFA

Update to the latest cloud navigation.

As a result of increasing projects, here is a little how-to with the summary of my previous articles. The main points are:

  • Azure AD Seamless Single Sign-On (PTA / PHS)
  • SAML Authentication (Azure AD as IdP & Citrix Gateway as SP)
  • Citrix Federated Authentication Service (FAS)
  • Microsoft Azure Multi-Factor-Authentication with Conditional Access

Requirements

  • Fully working Citrix Virtual Apps and Desktop Environment (StoreFront & DDC Minimum Version 7.9)
  • NetScaler with successful base configuration & activated Enterprise or Platinum license (Minimum Version 12.1 Build 50+ for native workspace app, for browser Minimum Version 11.1)
  • Configured Unified Gateway vServer
  • Internal and external DNS entries for Unified Gateway vServer (e.g. citrix.deyda.net)
  • Certificates for DNS entries (wildcard certificates are the easiest)
  • Existing Azure Tenant with Azure-AD base configuration (Domain, AAD Sync) & activated Azure AD Premium license
  • AD Connect version installed and configured (Minimum Version 1.1.644.0)
  • Firewall release for *.msappproxy.net on port 443
  • Domain administrator credentials for the domains that connected to Azure AD via AD Connect
  • Installed Authenticator App on Test User Mobile Phone

Microsoft Azure MFA Cloud Service in Citrix ADC

To complete my previous article, I also directly implemented and tested Microsoft Azure MFA Cloud Service in my test lab. In this post I go straight to the ToDo’s for implementation. For more information on MFA and the differences between Local and Cloud, please read my previous post.

It is important that all my information has the status of March 2019 and since it is the cloud, it will soon be obsolete again.

Microsoft Azure MFA Server in Citrix ADC

Update:

As of July 1, 2019, Microsoft will no longer offer MFA Server for new deployments. New customers who would like to require multi-factor authentication from their users should use cloud-based Azure Multi-Factor Authentication. Existing customers who have activated MFA Server prior to July 1 will be able to download the latest version, future updates and generate activation credentials as usual.

During one of my current projects, I launched a PoC for two-factor authentication based on Microsoft Azure MFA. Azure multi-factor authentication requires users to verify and confirm their signups using a mobile app, phone call, or text message. You can use it with Azure AD or the local AD.

It is important that all my information has the status of March 2019 and because it is the cloud, quite quickly become obsolete again.

Multi-Factor Authentication

The safety of the two-stage check is at level approach. The multiple authentication factors poses a major challenge for attackers. Even if an attacker can find out the user’s password, this is useless unless he or she is also proficient in the additional authentication method. This works by requesting at least two of the following authentication methods:

  • Something you know (usually a password)
  • Something you have (a familiar device that can not be easily duplicated, like a phone)
  • Something that you are (biometrically)
