DHCP problem using Leap and TKIP with Cisco ACS

[mbluemel]

I have set up a lab environment using a Cisco 1231 access point authenticating with Cisco ACS 3.2. The security settings are for LEAP authentication with TKIP and WPA. I can connect with it and see that authentication is passed on the ACS. I do not receive an ip address. I am obviously doing something stupid but cannot find it. Any ideas would be great.

Have you tried configuring LEAP with a Local Radius server on the AP to see what happens?

Although I havent tried it using the local radius server on the access point I actually had this working a fortnight ago on the same access point. The only difference is the ACS is on a different server now.
