Description

 

This article contains the lists of resources related to SAML authentication method applied to various features in FortiGate.

 

It has been organized into four sections that cover SAML usage in:

 

  • General Settings.
  • FortiGate administration.
  • Outbound firewall policies and proxy policies.
  • SSL VPN access.

 

Scope

 

FortiGate.

 

Solution

 

A high-level description of SAML is the acronym for Security Assertion Markup Language.

It is an XML-based open-standard for transferring the identity of data between two parties: an identity provider (IdP) and a service provider (SP).

 

Identity Provider: 

Performs authentication and passes the user's identity and authorization level to the service provider.

 

Service Provider: 

Trusts the identity provider and authorizes the user to access the requested resource.

 

SAML Flow when FGT is iDPSAML Flow when FGT is iDP

 

Note.

SAML library used in FortiOS does not support certificates with ECDSA (Elliptic Curve Digital Signature Algorithm) keys.

That applies to any feature using SAML as the authentication method.

 

See the list of resources below for help configuring and troubleshooting SAML Authentication in FortiGate.
