We have an infrastructure with a Cisco 4402-50 controller. We've just installed another controller, a 5508, and WCS as an "umbrella" to control the systems.
I have trouble joining some AP's to the 5508 controller. Note that all AP's connect fine to the older 4402 controller. It seems that our older AP's join fine, but the newer 1142 models just won't join. As far as as I can tell both controllers have exactly the same configuration (except for IP-adresses and such of course), I've even used configuration templates in WCS to ensure this.
If I go to Monitoring-->Statistics-->AP join on the 5508 controller, it says that the reason is "RADIUS authentication is pending for the AP". I don't understand this, because I've not set up any RADIUS authentication for AP's (only clients). I use MIC's and a local MAC database on the controller to authenticate the AP's.
Btw, the software controller version is 18.104.22.168.
