Accounting methods

The following accounting logging methods are supported by the server

Local 'detail' files
Local 'wtmp' and 'utmp' files
Proxy to another RADIUS server
Replicate to one or more RADIUS servers
SQL (Oracle, MySQL, PostgreSQL, Sybase, IODBC, etc)

from http://freeradius.org/features.html

Hi All,
Is it possible to have a freeradius box, that use a local copy of mysql for everything except accounting.
The accouting records would be written via a proxy to another MySQL box?

If so where do i configure it?

Thanks,

-Eric
