Relaying of accounting requests between Freeradius servers

[Patric]

Greetings list,

I have finally been able to upgrade my secondary freeradius server to 
2.1.3 and I must commend everyone on their hard work, the changes are 
great :)

I am having some trouble but would like to clarify my understanding 
before posting all my problem details in case I have misunderstood 
something.
My question is independent of server or platform version and addresses 
the fundamental mechanics of the relaying process.

I am using a virtual server setup to proxy accounting requests between 2 
servers for mirroring purposes.

As I understand the process server 1 receives an accounting request, 
which it will process according to its accounting section (in my case 
inserted into a table via the sql module).
If successful, it will then proxy the request to server 2, which will 
also process it according to its own accounting section.
Server 2 will then attempt to proxy the request to server 1 as per its 
proxy configuration, but will fail on a duplicate record, which will 
stop duplication from occuring.

Is my understanding in this correct, that server 1 will send the request 
to server 2, and server 2 will try to send it to server 1 again but will 
fail with a duplication error?


Many thanks
Patric
