The discovery URL is your AD FS host name followed by /adfs/.well-known/openid-configuration, for example https://fs.acme.example.test/adfs/.well-known/openid-configuration.
- Open the address in a browser to check that AD FS answers with its configuration.
- Paste the address as the discovery URL on Mediaflow's SSO setup page.
Mediaflow's servers call your AD FS server to finish each sign-in, so AD FS must be reachable from the internet with a certificate from a public certificate authority.
