I am planning a solution for a small ISP who needs a cheaper and straight forward billing system. Our solution contains FreeRadius running on Linux configured with UnixOdbc having a DSN of FreeTDS driver talking to SQL Server Express running on Windows. Front end app will be ASP.NET v2; our guess is that this solution’s TCO for the client and for us (developers) will be much less comparing to other platforms. It might sounds weird but we think its much cleaner than using third party patches or custom enhancement of FreeRadius code!
Has anyone used UnixOdbc in low to medium load? As this is the only thing we haven’t used in the past and are unaware how it will behave when we reach field testing!
