The eap settings need to be changed on the cisco wlc's also. For some reason
the default is only 1 second. We set ours to 30 seconds.  This change
improved the logon process for many platforms.

Just a little note on Macs and 802.1x.  Last year, I noticed that some
MAC laptops needed a small delay between the EAP-success and the
beginning of the key exchange.

You can test this theory by implementing a small delay in the Aruba
controller.  I haven't seen resent issues however and this may be a
thing of the past.

We at UC Hastings are using PEAP-MSChapv2 as our EAP type.
I noticed that by default the Mac client will setup an 802.1x profile
for our wireless network with PEAP, EAP-TLS, and TTLS.
With this setup the Mac client would authenticate every time but only
get an IP address half the time. By un-selecting EAP-TLS and TTLS and
only having PEAP selected in the 802.1x profile has fixed this problem.

Hi

We have a mixed network with a mixture of Cisco fat AP's and Aruba thin
AP's and we have found that some Apple Macs are having problems
connecting to the Aruba setup. It seems that the authentication
periodically fails and I see error messages like these from RADIUS :-

Auth fail logs from FreeRADIUS :-

Thu Jan 22 16:59:44 2009 : Error: TLS Alert write:fatal:bad record mac
Thu Jan 22 16:59:44 2009 : Error: rlm_eap: SSL error error:1408F119:SSL
routines:SSL3_GET_RECORD:decryption failed or bad record mac Thu Jan 22
16:59:44 2009 : Error: SSL: SSL_read failed in a system call (-1), TLS
session fails.


Auth fail reason from IAS :-

Reason-Code = 260
Reason = The message or signature supplied for verification has been
altered 


Has anyone else seen anything similar to this?

Thanks
