Two authorize instance

[Guillaume Chartrand]

Hi everybody,

I use freeradius 2.0.0 on red hat enterprise 3 AS and I set the authorize section to check the user credential with an sql database. This configuration works.
But I want to know and how to do that if it's possible, if the user isn't the sql database, can freeradius check another database, like an ldap database. So when the user is in the sql database he gain access, if not he look in a ldap database and if he are present with valid credential, he gain access.
Here my current authorize and authentification section :
authorize {
	preprocess
	chap
	mschap
	unix
	suffix
	sql
	eap
	expiration
	logintime
	pap
}
authenticate {

        ntlm_auth
        Auth-Type PAP {
                pap
        }
        Auth-Type CHAP {
                chap
        }	
Auth-Type MS-CHAP {
                mschap
        }
        unix
        eap
}
