We are using home realm discovery to redirect users to the appropriate IdP, depending on their email domain. This approach works for many of our connections. However, for one domain, it does not redirect and instead goes directly to a username/password page.
- The cause of this issue was the use of the same Identity Provider domain for two different connections that were enabled for the same application. In this scenario, the user expected to be redirected to a Google login page, but instead, they were being redirected to an ADFS connection login page, which appeared unfamiliar to those users.
To address this problem while maintaining the same email domain, we recommend disabling the connection you do not intend to use for each of your applications.
