Bridging RADIUS Servers

Dear All- Excuse my ignorance. Our company uses RADIUS today for network (802.1x) authentication. We're merging with another company who also uses RADIUS for the same purpose. Is there a config document which shows how I can configure Free Radius to proxy 2 completely different, existing RADIUS servers to authenticate users. The idea is that if one existing RADIUS server doesn't contain user information, a second RADIUS server can be queried for user info. Failing both lookups, the user will be declined. I'd appreciate any helpful tips. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
