FreeRadius 0.15.7_8 and you are using a SQL database ?

[Gertjan]

What I found in the logs during FreeRadius upgrade to version 0.15.7_8 :

........	pfsense	Jan 17 16:10:15 logportalauth[2538]: Zone: cpzone1 - RADIUS ACCOUNTING FAILED : No valid RADIUS responses received

Stopping the FreeRadius in the GUI, and starting it on the command line "raduisd -X" reveals :

which means the scripts expects new colons in (some) tables.

Checkout the new schema here /usr/local/etc/raddb/mods-config/sql/main/mysql/schema.sql

Backup 'radius' or whatever you called your database, wipe all tables and 'execute' the schema.sql file to re create the tables.
