Hello @Majd Nakhleh ,
Are you attempting to Azure import data into Ardog? or attempting to activate Azure AD Single Sign-On? I appreciate it if you could provide detailed information which would assist me know and understand your issue better.
I was reading this blog and discovered that you must select Resource group & region as the default, however there are many additional resources that you may import such as Virtual machines, Disks, Load balancers, App Service Plans, Resource groups, and so on but there seems to be no supported way to use Azure AD user group instead resource resource during import.
Hope this was helpful.
