Freeradius Checkrad Redback

[ahissi jean-françois]

Hello,

I need help!

I have a freeradius server 1.1.3 with mysql 4.1.11 backend
and we manage ip address pools with the NAS (Redback SMS), it works fine.

Now we need to have subscribers groups with particular ip address  
pools  for
each group.

I don't how to configure it with the NAS so i want to manage this with 
freeradius
but i don't exactly know how to configure it with users file because i 
think that i can't use
at the same time mysql database and users file.

thanks for your help!
