Hi, I have the following platform: FreeRadius Version: freeradius-server-2.1.11 OS: Ubuntu 11.04 I did all the instructions in "http://wiki.freeradius.org/SQL-HOWTO" to activate mysql in free radius, but I get the following error: Could not link driver rlm_sql_mysql: rlm_sql_mysql.so: cannot open shared object file: No such file or directory 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[166]: Failed to load module "sql". /usr/local/etc/raddb/sites-enabled/default[69]: Errors parsing authorize section. I just have a file named "rlm_sql_mysql.so" in the following address: "./src/modules/rlm_sql/drivers/rlm_sql_mysql" what do you think is the problem? Cheers
