Hi!
If acc module was compile with SQL/Radius support, it is not possible to deactivate it. IMO this is not a good design, as switching from radius to sql accouting requires re-compilation of the acc module.
It would be nice to deactivate the sql support for example by setting db_url to "" if the module was compiled with sql support.
btw: is there a bugtracker to track such feature request or bug reports? is the bugtracker on sourceforge used?
