I configured freeradius it was working well.Now I wanted to make it work with my sql.My distro is redhat9 and I am using the version mysql-3.23.54a-11.rpm.Free radius was working and authenticating user.But after configuring the files to make it work with sql it is not working well.It gave me the following errors.I did exactly that was defined in the resources.Like in the forum section of chillispot.org .Tutorial was posted by barteki. And other sites as well. root@chillispot rlm_sql_mysql]# radiusd -x Starting - reading configuration files ... Using deprecated naslist file. Support for this will go away soon.
