Description
A separate smart card for Enterprise Admin and Domain Admin accounts eliminates the automatic exposure of the private keys for the EA/DA accounts to less secure user platforms when the other accounts are used. Having different certificates on one card does not provide the necessary separation. The same smart card may be used by an administrator for both EA and DA accounts.
