Authentication registers on MySQL

[Felipe Neuwald]

Hi Folks,

I'm building a new freeradius server here, and I wanna make some 
implementations:

1. Log every authentication (sucessfull or not) to MySQL database;
2. but, log *only* the last 10 registers of authentication in database.

The database connection is already working ok, and I'm retrieving the 
user information from radcheck table.

Does anybody knows how to implement this?

Thanks,

Felipe Neuwald.
