  • 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)
