Logging question

[Curt LeCaptain]

Currently I'm using the mysql logging functions of FreeRADIUS and I'm
logging two different things:

Dial-up customers that log in with just their username (username)
DSL Customers that log in with user at domain (username at domain.com)

I'm wondering, how would I get it so that both log the same way, that
is, just username, not the suffix @itol.com.  Any advice would be great!

Thanks,
