I have a ASP.Net Web Forms application (.NET Framework 4.7.2) written off-the-shelf, configured with WS-Fed. SSO works fine.
I want to be able to turn on or off the SSO functionality. Say for example our ADFS is down. I want to be able to change a setting in my web app, and disable SSO, and work without SSO. This would be, get the user's credentials and authenticate against AD. This is the way other web form applications which have not been added SSO capability currently work.
How can I turn off/on SSO in my Web Forms web application? how?
