We're having a problem with web-authentication on our 4404/WisM controllers since we moved to software rev 5.x (currently running 18.104.22.168).
With software rev 4.x our web-auth SSIDs would send the authentication requests to a Cisco ACS4.0 which would then authenticate the users against MS Active directory.
Now (with rev 5.x) the same SSIDs cannot authenticate users against AD, the error in the ACS is:
Auth type not supported by External DB
Found the following Cisco Doc regarding the problem: Cisco Secure ACS and Windows AD EAP/802.1x port authentication fails with the Auth type not supported by External DB error message - Case Number K24308566. Done a packet capture on ACS to see authentications coming in and the ones that fail with above error are using CHAP - from the Cisco documentation, MS AD doesn't support CHAP.
Any ideas on how I can get the web-auth working again with software rev 5.x ?
