Do you have to buy Premium P2 for every licensed user to use Privileged Identity Management

[Nathan Dees]

Do you have to buy Active Directory Premium P2 for every licensed user in your tenant to use Privileged Identity Management or can you just purchase it for the admin accounts you want to manage? $8 a month for every user is steep if you just want to control admin access but not too bad if we just had it on our admin users.

I think you only need as many licenses as you need for users who would be potentially elevated to an admin using the PIM feature of P2. This page seems to indicate that you assign it on a user basis, not for the whole org: https://azure.microsoft.com/en-us/documentation/articles/active-directory-privileged-identity-manage...
