User authorization via 802.1x

[arroyob]

I am checking the 802.1x features with Windows 2000, catalyst 3550 and ACS3.0. The 802.1x authentication works fine but I am trying that User IP address to be assigned by ACS but it is not working (first, is this possible?).

I see on Catalyst debug that RADIUS is sending configured attributes (6,7,9,10 and 22) (but the authorization step is not being reported on debug) for this user but my Windows 2000 is not getting the IP address..

Any idea about this?

Take in mind it is my first contact with ACS software.

I don't think what you are trying to do is possible. Sure, you can push addresses to users after authenticating them but you need access servers for that.
