AAA server is nowadays an essential product on nowadays enterprises to control network equipments, and provides Authentication, Authorisation, and Accounting over all network devices. AAA is part of the management policy.
In parallel, the same server can be used for VPN users.
so do you think each company must ship two ACS servers to the company or we can uses the same server for both services? (but this way the administrators of the ACS server will be the same people so they can grant themselve access to any network equipments)
can i have a clear analysis about this critical issue?
