SQL for return attributes only?

ObDisclaimer: I have googled my best google, and read all the docs I can find, so please be gentle if this is a dumb question. Is it possible with freeradius to use SQL to retrieve certain return attributes (in this case rate limiting values for PPPOE sessions), whilst still handling authentication through PAM? In other words, I don't want to authenticate using SQL, I simply want to grab an attribute or two from a MySQL database, indexed by username, if the PAM authentication succeeds. I'm using the Winbind PAM module to authenticate against a Windows AD (a "legacy" requirement), so storing passwords in MySQL is a non-starter. -- hugh -- Hugh Messenger hugh@alaweb.com
