Hi Alan, Thanks for helping me in configuring my freeradius with mysql. I've uncommented the "sql" in the file /usr/local/etc/raddb/sites-enabled/default . And now I've seen message trying to commucinate with mysql. But still there is a problem of not getting the mysql driver. I am using MySql 4.1.2. Please suggest to work out. Here is the piece of output emphasizing the errors. rlm_sql (sql): Could not link driver rlm_sql_mysql: rlm_sql_mysql.so: cannot open shared object file: No such file or directory rlm_sql (sql): Make sure it (and all its dependent libraries!) are in the search path of your system's ld. /usr/local/etc/raddb/sql.conf[22]: Instantiation failed for module "sql" /usr/local/etc/raddb/sites-enabled/default[123]: Failed to find module "sql". /usr/local/etc/raddb/sites-enabled/default[33]: Errors parsing authorize section.
