I don't have Apple Business Manager but I've been told, login to MacOS with Entra credentials should be possible. I start up fresh MacOS, register new local account, install Company Portal, register the entra user account with CP, perform device registration, but still I need to use that local account to access macos. See my config below:

    I partly solved. First thing is, that you should not use User-based MFA in Entra for users who are attempting to log in to macos.

    Second discovery is, that the m365 user who enrolls macos in Company Portal, later cannot login in his own desktop. So, for that, the workaround is to enroll macos with using User A account, but real use will be then performed with User B account. That being said, a user who enrolls macos with CP, cannot login to desktop, other m365 users can.
