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 '[EMAIL PROTECTED]', 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
"[EMAIL PROTECTED]"; 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
