I'm trying to follow this guide to try out Access Manager using username+password authentication.
https://documentation.meraki.com/Access_Manager/Access_Manager_Configuration_Guides/Access_Manager_U...
The issue is on the Entra ID side.
I configured an exclusion in every conditional access policy for the app (yucky, but ok). So 100%, there is no policy requiring MFA.

Our authentication methods policy has been fully migrated to use modern policies.

Despite having every conditional access disabled through exclusion, Entra ID is saying the authentication failed because MFA is required. Everyone has to do the above migration - there is no choice.

So does this mean the entire section on using username/password authentication against Entra ID in the new Access Manager is a non-starter? Anyone who has it working at the moment will have it fail when their tennancy is forced migrated?
