same user on different service

Hello! I have a question about same 'username' from different services. Task: 1) Troublefree login users with same username, from different places(therefore different attribute) at the same time: - cisco console login(radius for cisco); - ppp(radius for dialup). 2) In some way delineate radius log for cisco from ppp radius log. aaa must be done on single freeradius server(...we have a one aaa server). May be use a different group or realm? Please, I'd like to listen our recommendation or link that this explained. [freeradius version 1.1.3, latest I can't,only this!!!] Thanks!
