Organization with only external provider login redirecting to type in password

Hello, I created a organization and i want them only to log in via external provider like microsoft activedirectory. the thing is that when i create a new user he gets redirected to the organization auth page and has to type in a password even if i have disabled password entry. only if i press the back button i get redirected to the external identity. this looks uncommon for me. shouldnt the user be directly redirected?
