currently we have ADFS SSO setup in our org and I would like prevent our users to login to Salesforce using the general login.salesforce.com link but we do not want to check the "Prevent login from https://login.salesforce.com" because if our ADFS goes down even us (Admin) unable to login. So we just want our users to use the mydomain url to login as SSO but not Admin and I found it can be done by setting up delegated authentication.
So will this still work with ADFS SSO? What will be the sequence? If i have this delegated authentication setup, the user tried to login through https://login.salesforce.com and our webservice will simply return false? So they will need to use mydomain url? If they use mydomain url to login then it will bypass delegated authentication?
