Martijn_van_Loenen - It looks like the feature of being able to sign in at the Mac login screen using your Azure AD Credentials is still not available in the Preview. I assume that means its going to be released in the fall but it would be nice to test it in the Preview stage before its actual general release. Right now it looks like you can only use Kerberos for syncing to a local account which is not what they are speaking about in this article. Being able to actually sign in to the MacOS with your live company Azure AD credentials and then having Intune driving all of your SSO experience would help tremendously in managing Mac computers with an Azure infrastructure. I hope they provide an update to this article when the feature is released.
