Hi folks, I have a bit of a conundrum trying to implement FreeRadius for a system where users from multiple ISP names must all authenticate in the same place, and I'm hoping a more experienced user can shed some light. In a nutshell, I need to do the following: -Check the 'called-station-id' of an incoming RADIUS request -If the id is A, B, or C, set a hint/realm flag to "alpha" -If the id is D, E, or F, set a hint/realm flag to "beta" -If the id is anything else, set a hint/realm flag to "gamma" -Based on the value of the hint/realm flag, rewrite the username before attempting authentication (by adding '@ispname1', '@ispname2', etc.) -Conversely, if the username already looks like 'user@ispname', leave it alone For completeness' sake, I'm performing the authentication against a Postgres database. In its current state, the system is able to happily authenticate users as long as the username is provided in the format "username@ispname"; otherwise they are rejected. Our old RADIUS system (using Radiator) appears to call a perl script to perform this username rewriting, but that just seems like a nasty hack that I'd prefer to avoid. Any advice on this would be immeasurably appreciated. Thanks, J. Fox
