How can a user see his/her usage report on ACS 3.0? Is there a web-based utility which users can login and see his/her report? And a second question: how can i add a user time quota without regarding to his/her used quota? Thank you.
ACS does not have any utility to calculate the usage quota for users and you will not be able to see this info. You can add some usage time quota by using group setup in ACS.
