Redirect after login using Symfony 3 config

[MuamarAli]

Hello, good day everyone.

Is it normal that I can't redirect after Logged in Saml Login using the Symfony configuration?

`light_saml_sp:

            provider: database_users
            user_creator: user_creator
            login_path: /saml/login
            check_path: /saml/login_check
            default_target_path: saml_checking
            always_use_default_target_path: true
            require_previous_session: true

`

As you can see, I set route for the default_target_path But doesnt redirect to the route.
Is it normal? or no?
Or i have to need to update my IDP for the redirection after login?

Thank you.
