Microsoft IAS with RRAS

Hi,

I am having a problem using IAS to authenticate users on my RRAS server. Both are Windows 2003. I'm in native mode and have 2 other 3rd party devices successfully authenticating against this IAS server. When I use just Windows authentication on the RRAS, it works fine but I would like to centralize all requests on the IAS.

My clients get error 930. I have done MSKB299684 and enabled the IAS server to read user accounts in Active Directory.

Do I need to add a Policy on the IAS? If so what attributes should I check for?

Thanks
