The Cisco AAA Radius authentication is broken and I need to modify radiusd to solve the problem.
I am trying to implement a negative or reverse authentication,
a sort of black list: if the user (actually, dialing phone number) is present
in the Radius database, the authentication should be Access-Reject and
is the user is missing the authentication should be Access-Accept.
The whole thing is very simple, there are not even password. Only the presence or absense of a user is relevant.
I was looking at the file 'auth.c' but I would rather get some advise from some knowledgeable Radius programmer.
Where is the easiesto or most straightforward part to make the modification? I tried:
return -result;
but it didn;t work. :-\
TIA,
