same user on different service

["Николай Г. Петров"]

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!
