Radius server is not available

I am seeing the following fault on my WLSE express: Radius server is not available

The following is what I see in the AAA-server-trace.log:

08/27/2007 20:15:23: P15467: Packet received from

08/27/2007 20:15:23: P15467: Checking Message-Authenticator

08/27/2007 20:15:23: Log: Request from Message-Authenticator validation failed

What is causing this Fault?

Re: Radius server is not available

Hi. It's likely that the "shared secret" or some other attribute isn't matching in your WLSE/ACS. In the troubleshooting guide, it mentions some of the things to look for:

of course, all of the settings for AAA authentication are found in the User Guide here:

But definitely the Message-Authenticator

check will fail if the shared secret is wrong, so that's probably where you want to look first.


Re: Radius server is not available

Make sure shared secret key is correct. Please type is again and do not copy paste.

Re: Radius server is not available

I should have mentioned that I can authenticate with leap using my wirless client.

I also double checked the shared secret and it is correct.
