SAP Afaria SP5, HF5 - Restricting the number of devices per user ID

Dear All,

I have installed SAP Afaria 7.0 SP5 on premise version which is integrated with Windows Active Directory. Can we control the enrollment with  number of devices per user ID? Is there any way to restrict this?

Can we extend the specific user group from AD to SAP Afaria, using user group creation from the admin console.?

Thanks in Advance.
