WLC 5508 Web Authentication issue with RADIUS WIN2012 NPS


We have a WLC 5508 with 2 WLAN. One with 802.x WPA2 authentication and Second one with Web splash page authentication.

We have a Radius server 2012 NPS. WAP2 802.x authentication work with Radius server.


Second wlan  Web splash page authentication not working with Radius server. Web Authentication works only with local user (Internal user created in WLC) NOT with Radius server. 

We would like the second WLAN (Web Authentication)  authenticated by both local user and AD credentials through Radius Server.

Open a case with Cisco and they are saying all the config in Cisco WLC are fine I need to contact Microsoft regarding this. 

This is the SNMP trap message

What are you seeing on the NPS side? Are you seeing the authentications as successful from that side?

Here is a link of how to configure the WLC to use an external RADIUS server in this case ACS for authentication captive portal.

Re: WLC 5508 Web Authentication issue with RADIUS WIN2012 NPS

How AD users authenticated by controller for web authentication ? Radius Server or LDAP server? 

In that document Radius ACS has an intenal user database that used to login. But is it possible Radius NPS server use to authenticate AD credentials? If yes then I need a screen shot for NPS network policy property for web authentication

I have an existing network policy for WPA2 clients and is working fine.
