Authenticating more than username/password

[David Young]

Hi, I was wondering if there's a way to make freeradius authenticate a client based on more than username and password?  for example, I want to limit a user to dial in only from a certain designated number (ANI) to prevent fraud.  My user lookup is done through postgresql.  Is there a way to do additional checks before replying to the NAS with an Accept or Reject response?  Maybe something that will do:   if (username and password and ANI) all match then     Accept else     reject     Thanks a lot, David
