[RADIATOR] Need to tightly integrate user and group using vendor specific attribute

[Ruchi Shah]

Hi,
     I want to tightly integrate users and groups.
     can i do it using vendor specific attributes?
     which parameters are required in request for that and which i can 
get in response back?
     can you  give me some hint for that?

     Thanks in advance.
