External Captive Portal errors and roaming between 2 APs.

Good day,


We are trying to integrate the external captive portal feature of the IAP with out IIS farm to deliver custom made portals (without clearpass). The IAP VC creates a VPN tunnel to a 3600 controller which integrates with our IIS farm and SQL Database as well as Radius.


We are using External Captive Portal + RADIUS Authentication.


We have the preliminary portal working fine, authentication and de-authentication works using 1 single IAP using classic ASP.

Using .Net we are having issues with the DEAUTH.


1st issue:

We are trying to get this to work with a 2+ IAP solution. The issue we run into is as follows:

1. User connects to IAP-1, receives portal, authenticates

2. User roams to IAP-2, receives portal again (basically a welcome back page).

            User should go straight out to the internet as they have a valid session.


I'm trying to identify why this is happening. Have any of you run into this before?


2nd issue is the following:

After rebooting the VC, we sometimes see the following error message delivered it seems by the IAP as it mentions 'tinyproxy'

"Unable to connect to external captive portal"



Any ideas on this topic is greatly appreciated. This is a tough one..
