How to setup daloradius with pfsense + Freeradius2 ?

[jek]

Hi,

I have added daloradius-0.9-9 in pfsense's www folder. and changed daloradius.conf.php as per my need.
After that I can see the daloradius GUI , but after inserting User Name and Password bellow error is coming.

Warning: main(DB.php): failed to open stream: No such file or directory in /usr/local/www/daloradius/library/opendb.php on line 29 Warning: main(): Failed opening 'DB.php' for inclusion (include_path='.:/etc/inc:/usr/local/www:/usr/local/captiveportal:/usr/local/pkg') in /usr/local/www/daloradius/library/opendb.php on line 29 Fatal error: Undefined class name 'db' in /usr/local/www/daloradius/library/opendb.php on line 32

Can you please correct me  or suggest me exact way to setup daloradius with pfsense?

Thanks in advance!
