Hi,
Strange one here, I have setup a WLAN with PEAP user authentication through ACS to the Windows database. My clients cannot connect to the WLAN.
From the logs, I can see no activity on the Radius server stats (as seen from the controller) and no failed login attempts on the ACS itself. The ACS/Radius is setup correctly on the controller and the controller can ping the ACS, but they just don't seem to be talking???
I have used this setup before, but the only difference is that the controller is a 5508 (done this with 4400's in the past) and the ACS is running on VMWare (Never done this before).
If I change the security to WPA2 PSK it works fine.
I want to use PEAP for user authentication. NOT Machine auth. I have a certificate installed on the ACS and it is in the trust list of the client PC.
Any help appreciated!

hi,
Can you make sure that the shared key used between cisco wlc and acs are same
and one more thing, check you are using correct port number, the default port number for radius server on wlc(1812) is different
from the acs server portnumber which uses(1645).
so make sure on wlc you have 1645 port configured when configuring cisco radius server.

Hi,
Thanks, I've checked all that previously and it was OK. Great advice though, especially about the port numbers so 5 stars for you my friend!
However, the customer rang me this morning to say that it 'mysteriously' started working! I don't look after the customers network or ACS (Only the new WLAN), so I can't say that there was a glitch, but if there was it seems to be resolved now.

Hi dselfridge
I'm currently having problems finding resources on how to setup ACS/IAS on my WLC 5508. Do you have any reccommended sites or resources that would help?
Thanks!
