i was going through the Trust & identity management solution and i stopped when i read the IBNS is important for the 802.1x.
i really didn't understand the function of the IBNS coz i know that Cisco ACS works fine with 802.1x and can take care of the AAA, so what's the real function of the IBNS ???
i appreciate if you can send me a document that explains in technical deaitls the inter-functionality between ACS, IBNS and NAC, and how can i design a Trust and identity management solution.
