What will be the authentication type is IIS if SAML is enabled?

SAML for ASP.NET
1

I need to switch between Windows authentication and SAML Authentication, in my application.
Based on the Value in config file, I need to redirect to SAML Authentication page or I need to take Windows UserName.

For now, I have Hosted my website in IIS and it is prompting for Windows authentication and then it is checking for value in Config and redirecting to SAML.

If SAML is enabled , Windows authentication popup should not get displayed.

You shouldn’t have to configure the authentication type in IIS.
It’s the same as if you were performing forms authentication in your application rather than using SAML SSO.
