Unlike early rhev3 beta releases, the authentication server configuration ( Active Directory or IPA) has been moved to seperate utility called ‘rhevm-manage-domains’.
Installing rhev3 is that easy now.. It is as simple as that, firing ‘rhevm-setup’ command in a linux system..
Refer:
rhevm-setup
Once you ran above command, you have to configure authentication setup ( Active Directory or IPA ) by running ‘rhevm-manage-domains’ command..
