auth flow according to attribute value

[Giuseppe Tricarico]

Hi all

I'm new to freeradius, I would like to know if there is a module that 
basing on some attribute of the radius request execute a module, i.e. I 
want to alter the execution flow of the authorize section ... This give 
me the possibiltity to manage some "business logic" through the 
configuration of radius server...

For example I could analize the "nas-port-type" attribute in the request 
and autheticate users on different database, basing on such parameter..

Best regards
