FS trying to authenticate accounting data

["Jim L." <jdl@imaginenet.net>]

Hello group.

I am running FreeRADIUS 2.0.4 and I am attempting to setup a configuration 
based on the "robust-proxy-accounting" site example. In short, I could not 
get it to work. To attempt to debug the problem, I pared down the 
configuration so the only part that was active was the part that it supposed 
to send the accounting data to a detail file. However, even that small piece 
does not work. The errors I am getting in the debug logs are

auth: No authenticate method (Auth-Type) configuration found for the 
request: Rejecting the user
auth: Failed to validate the user.

However, the configuration to log the data the detail file is only setup for 
accounting, not authentication. This leaves me confused as to why FS is 
attempting to do authentication. The relevant parts of the configuration 
that are active during the test and the debug log is listed below. Any 
assistance would be appreciated.

Thank you,

Jim Lohiser
