AnyConnect Azure Active Directory SAML Configuration
This document highlights how to setup authentication with Azure AD using SAML for AnyConnect VPN on the MX Appliance. SAML is an XML-based framework for exchanging authentication and authorization data between security domains. It creates a circle of trust between the user, a Service Provider (SP), and an Identity Provider (IdP) which allows the user to sign in a single time for multiple services.
SAML authentication requires MX firmware version 16.13+ or 17.5+
For additional information, refer to the AnyConnect configuration guide.
