IAP 135 - Radius authentication problem / server down message

HI there.

 

I have two IAP 135, running version 6.3.1.4

The IAPs have been configured with the following static ip address:

  - IAP 1: 192.168.10.4

  - IAP 2: 192.168.10.5

  - Virtual Controller IP: 192.168.10.3

 

Every thing works great, except for the radius authentication.

Our radius servers are two windows 2008r2 running NPS. It also works very fine and it has been used for lot a authentications on other devices.

 

The problem is: The IAPs GUI keeps alerting that the radius servers are down ( messages attached ): "Authentication Server Radius1-ServerSync is down", but they are not, they are up and responding very well.

Because of that, a lot of authentications fail without even hit the radius servers.

To make it work, I have to wait ( for the radius dead time ), and try again a lot of times.

When the authentication request hits the radius servers, it works. But the a lot of those auth requests doesnt even reach the NPS server. And again, the radius servers are up and working great.

 

The IAPs logs shows the message: ( attached )

 

Hope you guys can help me again.

 

Thanks a lot
