I am trying to get WDS configured and working, but for some reason it is not correctly authenticating to the IAS radius server. I followed the cisco document exactly (except configured IAS instead of ACS).
I get the following when debugging radius authentication
*Mar 15 17:49:24.119: RADIUS: no sg in radius-timers: ctx 0xD4F44C sg 0x0000
*Mar 15 17:49:24.119: RADIUS: No response from (10.186.1.20:1812,1813) for id 1645/142
*Mar 15 17:49:24.119: RADIUS/DECODE: parse response no app start; FAIL
WDS authentication uses LEAP protocol only (Cisco's proprietary). I didn't find any information saying that IAS supports LEAP. So, if you don't have an ACS, an option would be using the Local Radius Server on AP to authenticate WDS only. Also, if you have WLSE Express (only this) you can use this one for WDS authentication once it has AAA Server function.
