Alvarion Accounting with free radius

I am writing to see if anyone on the list is using Alvarion breezeAcess radios with free radius for accounting? If can you give me a helping hand, I am trying to get freeradius to understand what the radios is sending and have it mapped the attributes to the right sql fields. I can send some debug data if needed . We are in Russia working on a project for schools kids and the orphanges and we need ot account trafice with our network of Alvarion radios !!!! -- Robert Dukes
