proxying without relam

[Tevfik Ceydeliler]

Hi,
I am really newbie about free radius.
I try to use sqlip pool to assign IP address to my authenticated user.
But I have two type OTP server to check password :mOTP and Secovid (one 
time password dungle)
How can I send my authenticate requests  those two OTP server depend of 
user ?
But, I cant use username at realm  type usernames. My users use only username.
Any idea?
