Looking at implement DUO for M365 with the new method for SSO. I am just trying to understand if it has an impact on Azure Seamless Sign On and any Conditional Access Policies on the federated domain. As far as i am aware CA Policies apply after authentication so i guess they will still be enforced?
Unfortunately, when using any third-party federated authentication provide, Azure Seamless Single Sign-on will not work as it requires users to see the Azure username/password page.
Most other Conditional Access policies will continue to work as expected! We’ve worked with Microsoft to ensure that we built our application in a way that that is complementary for our joint customers!
Please let me know if you have any other questions.
