Error messages in System log of IAS server during VPN authentication

Authentication on our 3015 concentrator is handled by Microsoft Radius (IAS). Under the server's Events/System Logs we have the following error appearing:

"A request was received with an authenticator that is not valid from client Cisco VPN 3000."

We seem to get 3-4 errors after every successful authentication. I'm beginning to suspect it's client related (v3.6.3) since the errors don't appear when I "test" the authentication from the VPN admin webpage. Everything seems to work fine, I just don't know if this is an issue or not.

It sounds like a client issue. I don't think that that error message is hindering anything.

Actually the problem was, the accounting server defined for that particular group, did not have the secret password defined which would explain why the error only appeared when using the client.
