"Network Access Restriction" Question?

[kendo.igor]

We are using PIX 515E and Cisco ACS 3.0.2.

What is NAR. I've read almost every Cisco document on the topic, but I was hoping that someone could explain it to me in plain english and perhaps by siting an example of how it may be applied.

Also, does it work with RADIUS and TACACS+?

Thanks.
