I have multiple connections setup in my Auth0 tenant, one DB and few enterprise. Each enterprise connection has “Display connection as a button” unchecked. Each enterprise connection has at least one email domain specified. Authentication Profile is configured as “Identifier First”. Whit the above setup, when logging in without “organization” option (and without “connection” option), the enterprise buttons do not show which is expected and desired, and then realm discovery picks up correct connection. The erroneous behavior occurs when I do specify specify “organization” for login, then the login screen (the new one) shows ALL the enterprise connections for that organization, which is not intended.
With the above configuration, I was expecting the connection buttons to not show up ever, regardless if organization is specified or not.
