Hi Karlis
If I understand your question correctly, you don’t want the login-landingpage, you want to get immediately re-directed to you login at the Microsoft Azure AD. I’m not a big fan of that approach, but in the end: that’s your call :)
You can implement an ‘Anonymous’-profile-logic that redirects to a home-page that makes use of the URL redirector widget: https://marketplace.mendix.com/link/component/115219
Hope this helps!
Kind regards,
