It pains me to send this to the list as I know I’m going to get shot down for missing something obvious, but I simply can’t think of where else I need to set this up.
I’m moving my web proxy servers from ISA to TMG and need to declare the TMG servers in my freeradius servers so that they accept NATed requests from my MS IAS servers. I have added the new servers to /etc/raddb/clients.conf in the same way as the ISA servers were, and entered a shared secret (simple to try and help debug this). I have then added the same servers to my clients list in MS IAS with the same shared secret.
The problem is that the FR server is reporting a shared secret mismatch when requests come from the new servers:
rad_recv: Access-Request packet from host 4.4.4.4 port 62463, id=1, length=211
Received packet from 4.4.4.4 with invalid Message-Authenticator! (Shared secret is incorrect.) Dropping packet without response.
Going to the next request
I have typed and retyped the shared secret several times on both FR and IAS sides of the conversation. Is there anywhere else in FR I need to declare the new servers that I have missed, or do I need to concentrate the efforts to the IAS servers?
