ACS Appliance rejects users from Cisco 4400 WCS

Has anyone seen this error code in your ACS logs? If so, what does it mean? This problem is only occurring with the Wireless Controllers and LEAP users. Below is the message:

"Radius extension DLL rejected user"

Thanks.

Re: ACS Appliance rejects users from Cisco 4400 WCS

Normally I think that means the external database failed the authentication. In the case I just had they were using the NT database and had duplicate accounts with different passwords (one on the domain, and a local NT user). Try different usernames, or try creating a new user just for testing. Make sure the passwords are correct, etc. Also, try using tactest or radtest instead of the Aironet to see if it works for that.
