freeradius and mysqld.sock location problem

Hi, I am having problems with freeradius connecting to a mysql database. Freeradius reports the error: rlm_sql_mysql: Mysql error 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) The mysqld.sock file is acutally located at /home/system/var/run/mysqld/mysqld.sock, so I created a symlink to that file in /var/run/mysqld, and now freeradius reports the same error, but with a (13) at the end instead of a (2). Is there anyway to configure freeradius to look in the correct location, or is there another work around? Thanks in advance, Ben
