How to fix admin login page being redirected to SSO instead of default

This article describes how the login page is being redirected to SSO even though it is not set up.

Scope

FortiGate.

Solution

The first thing necessary to check is the SAML settings on the FortiGate:

config system saml
set status enable

set default-login-page sso <--
set default-profile "super_admin"
set idp-entity-id "https://custom1.fortigate.com/saml2/saml2/JumpCloudlab"
set idp-single-sign-on-url "https://custom1.fortigate.com/saml2/saml2"
set idp-single-logout-url "https://custom1.fortigate.com/userconsole"
set idp-cert "REMOTE_Cert_4"
set server-address "1.1.1.1"
end

In the above settings, it is possible to see that the default-login-page is set to SSO, which redirects to SSO instead of the default page. It is necessary to change the settings below:

set default-login-page normal

Once the changes are made try to log in again and it will not redirect to the SAML login.
